17.1 Role of emotions in goal setting
Where the chapter begins
Note that the workbook does not start with markets at all. It starts with stress, and with the observation that financial behaviour is one of several outlets people use for it. Over-eating, over-exercising, oversleeping and over-spending are treated as the same class of response — which is why the remedy that follows is a behavioural remedy, not an investment one.
The three-stage life of a stress behaviour
| Stage | What happens |
|---|---|
| 1 | Provides a good feeling, relief from stress, escape from immediate pressure |
| 2 | In moderation it is GOOD — it takes the sting out of emotional stress |
| 3 | It rarely stays moderate, and invariably leads to MORE stress in the future as the economic impact kicks in |
Stage 2 is the one most people misread. The workbook does not say the behaviour is wrong. It says that in moderation such behaviour is GOOD. An adviser who tries to abolish it entirely will fail, and will also lose the client. The problem is not the behaviour; it is that it does not stay moderate.
And stage 3 names the vicious circle precisely. The spending relieves stress today and creates financial stress tomorrow, which then requires more relief. The loop feeds itself.
The adviser's role, stated in one sentence
Learn the phrase SELF-LIMITING. It is the design principle for everything in this chapter. The adviser does not police the client, does not lecture, and does not rely on the client's willpower. The adviser builds an arrangement that runs out on its own — a fixed budget, a separate account, an upper limit, a ground rule. The brake is built into the structure, not supplied by the client's self-control in the moment.
Behaviour 1 — Retail therapy: stress buster or escape mechanism?
The two steps
| Step | Action |
|---|---|
| First | Make the client CONSCIOUS that the behaviour is induced by stress |
| Second | Have a SPECIFIC BUDGET for indulging in it |
Note the order and the logic. Awareness comes first because a client who believes they are simply shopping will not accept a budget for it. Once they recognise the trigger, the budget stops feeling like a punishment and starts feeling like a tool.
The extreme case
The phrase to hold is SELF-IMPOSED BRAKE... FROM AN IN-BUILT EXPENSE LIMIT. The separate account works because when the money in it is finished, the shopping stops by itself. No decision is required at the moment of temptation — and the moment of temptation is exactly when decisions cannot be relied upon.
The workbook's verdict on credit cards
This is a strong statement and it is examinable as written. The reasoning follows directly from the paragraph before it: a credit card is the exact opposite of an in-built expense limit. It removes the brake, defers the consequence to a statement that arrives weeks later, and therefore induces impulsive spending.
Note the qualification though — "for MOST people." The workbook is not making a blanket prohibition. It is saying that for a person prone to stress-driven spending, the instrument itself works against the remedy.
Behaviour 2 — Too many and too frequent transactions
Samuelson's quotation
Learn the attribution: PAUL SAMUELSON, Economics Nobel Laureate. And note the sting at the end of the quotation — he lists the local Merrill Lynch office alongside the casino and the racecourse, which is to say a brokerage can be a gambling venue too, depending entirely on how it is used.
Action bias
ACTION BIAS — the need to DO something — is a new term introduced in this chapter, and it sits directly against what investing actually requires: long term consistency and long years of patience.
The consequence is stated exactly: TURNING AN INVESTMENT ACTIVITY INTO A TRADING ACTIVITY. The portfolio may hold the same kind of assets, but the activity has changed character — and with it the cost, the tax treatment and the probability of success.
The remedy
Note the words ONLY WAY and IN ADVANCE. The priming must happen before the market moves, because once the client is emotionally charged it is too late to teach patience. This is the same design principle as the separate account — the brake is installed while the client is calm.
Behaviour 3 — Chasing past performance
REVERSAL TO THE MEAN is the technical reason the behaviour fails, and it is worth stating plainly: an asset class that has run far ahead of its long-run average tends to come back towards it, so buying last year's winner is frequently buying at the point of maximum disadvantage.
The rear-view mirror image is examinable and worth quoting exactly.
The remedy — two limits
| Level | Control |
|---|---|
| Across asset classes | Pre-decided asset allocation policy with UPPER LIMITS for each asset class |
| Within an asset class | MAXIMUM EXPOSURE LIMIT for a specific security |
Two limits at two levels — both examinable, and both are again SELF-LIMITING devices. When gold has run up and the client wants more gold, the answer is not an argument about gold. It is: "the policy you signed caps gold at 10 per cent, and you are already at 14." The limit does the refusing, not the adviser.
Behaviour 4 — Home country bias
Three sources of familiarity are named: the MARKETS, the COMPANIES, and the REGULATORY ENVIRONMENT. And the cost is stated precisely — the lost benefit is diversification into asset classes which do not move in tandem with the local securities. Correlation, not geography, is the point.
The five other reasons
| # | Reason |
|---|---|
| a | LACK OF KNOWLEDGE ON OPPORTUNITIES OUTSIDE THEIR HOME COUNTRY |
| b | HOME COUNTRY LAWS MAY PREVENT DOMESTIC INVESTORS FROM INVESTING OUTSIDE INDIA |
| c | LACK OF ACCESS AND HIGH COST OF ACCESS WHERE AVAILABLE |
| d | COMPLIANCES WITH THE TAX AND OTHER LAWS OF THE OTHER COUNTRY, WHICH AT TIMES MAY BE IN CONFLICT WITH THE LOCAL LAWS |
| e | LACK OF EXPERT ADVICE ON SUCH ASSET CLASSES AS THE ADVISERS THEMSELVES ARE NOT WELL VERSED WITH SUCH ASSET CLASSES |
Five reasons — and note that reason (e) blames the ADVISER, not the client. That is unusual candour in a workbook, and it sets up the remedy given below.
What has changed in India
LRS limit: USD 250,000 (two hundred and fifty thousand US dollars) per resident. Learn the figure.
Two routes, then: the LRS route (remit and invest directly, up to USD 250,000) and the domestic mutual fund route (invest in rupees in an Indian scheme that invests overseas). The second requires no remittance at all, which removes reasons (c) and (d) for most retail clients — and the workbook names S&P 500 and Nasdaq 100 as examples available as Indian schemes.
The antidote
Two steps, in that order — the ADVISER gets educated FIRST, then educates the client. This follows straight from reason (e). An adviser who is not well versed in these asset classes cannot remove the client's bias, because the adviser shares it.
Think of it like this
The self-limiting brake — the sweets jar with a lid you can only open once a week
A mother who wants her son to eat fewer sweets has two choices. She can stand beside him at every meal and say no — which works while she is standing there and fails the moment she leaves. Or she can buy a smaller packet once a week and put nothing else in the house.
The second approach is what the workbook means by making behaviours SELF-LIMITING, and it is the design principle behind everything in this chapter: an adviser's role lies in understanding these impulses and PROVIDING WAYS TO MAKE SURE THAT SUCH BEHAVIOURS ARE SELF-LIMITING.
For retail therapy the device is a separate account where the budgeted amount is kept, spent only through a debit card or by withdrawing cash. The workbook states the principle exactly: the important thing is to have a SELF-IMPOSED BRAKE on the behaviour which comes from an IN-BUILT EXPENSE LIMIT.
Why this works and lectures do not: willpower is weakest at the exact moment it is needed. A person under stress at 11 p.m. on a shopping app is not going to recall a conversation about budgeting. But if the account has Rs 400 left in it, the transaction simply fails — and no willpower was required at all.
The same logic explains the workbook's hostility to credit cards: credit cards INDUCE IMPULSIVE SPENDING precisely because they are the opposite of an in-built limit. They remove the brake and post the bill to a future self who is not in the room.
Action bias — the passenger who keeps pressing the lift button
Watch anyone waiting for a lift. Within twenty seconds someone will press the already-lit button again. It changes nothing. The lift is coming at its own speed. But pressing it feels better than standing still.
That is ACTION BIAS — the NEED TO DO SOMETHING — and the workbook sets it directly against what investing actually requires: LONG TERM CONSISTENCY AND LONG YEARS OF PATIENCE.
In a portfolio the lift button is the trading screen. A client watching a falling market feels an almost physical need to do something, and the only somethings available are buying and selling. So they buy and sell. The workbook names the result exactly: too frequent and too many transactions, WHICH HAS THE IMPACT OF TURNING AN INVESTMENT ACTIVITY INTO A TRADING ACTIVITY.
Paul Samuelson, the Economics Nobel laureate, put the cure in a sentence worth memorising: "INVESTING SHOULD BE DULL. IT SHOULDN'T BE EXCITING. INVESTING SHOULD BE MORE LIKE WATCHING PAINT DRY OR GRASS GROW. IF YOU WANT EXCITEMENT, TAKE USD 800 AND GO TO LAS VEGAS."
And note how the workbook says the cure must be applied: the ONLY way to induce the client to curb such a tendency is to PRIME THEM IN ADVANCE with the benefits of patience and long term investing. In advance — because a client in the middle of a 15 per cent fall cannot be taught patience; they can only be reminded of it.
Chasing past performance — driving by the rear-view mirror
The workbook supplies its own image and it cannot be improved on: INVESTING BASED ON PAST PERFORMANCE IS LIKE DRIVING A CAR BY LOOKING IN THE REAR VIEW MIRROR. IT IS BOUND TO CRASH AT SOME POINT OR THE OTHER.
Think about what the mirror actually shows. It is perfectly accurate — that is the trap. Every twist of the road you have already travelled is displayed in sharp detail. The information is real, it is verifiable, and it is completely useless for the corner ahead.
So it is with a one-year return table. The numbers are audited and correct. Gold was up 30 per cent last year. That is a fact. And it tells you almost nothing about gold this year, because most asset classes have a CYCLE OF GROWTH AND DECLINE and there is an INEVITABLE REVERSAL TO THE MEAN.
The workbook's example is the client who invests in Gold when Gold goes up and shifts to Equities when equity markets rise — always arriving after the move, always leaving before the recovery.
The remedy is structural, not persuasive: a pre-decided asset allocation policy that has UPPER LIMITS FOR EACH ASSET CLASS, plus a MAXIMUM EXPOSURE LIMIT WITHIN a given asset class for a specific security. The limit argues with the client so the adviser does not have to — and, better still, the limit was agreed by the client when they were calm.
Home country bias — the family that only eats at restaurants on its own street
A family in Pune eats out twice a week and has done so for fifteen years, always within four streets of home. They know the owners, they know the kitchens, they know which place is clean. They are not being foolish — familiarity really does reduce a certain kind of risk.
But if a water shortage closes every kitchen on those four streets on the same evening, they have nowhere to go. Their comfort and their exposure came from the same source.
That is HOME COUNTRY BIAS: investors prefer home securities due to FAMILIARITY with the markets, the companies involved as well as the REGULATORY ENVIRONMENT, and thereby lose the benefits of diversification which come from investing into asset classes WHICH DO NOT MOVE IN TANDEM with the local securities.
Read that last phrase carefully, because it is the whole justification. The point of global investing is not that foreign markets return more. It is that they do not move in tandem — so when the local market has a bad year, the portfolio is not entirely at its mercy.
The workbook lists five further reasons beyond comfort: lack of knowledge; home country laws; lack of access and high cost; compliance with foreign tax and other laws that may conflict with local laws; and lack of expert advice because THE ADVISERS THEMSELVES ARE NOT WELL VERSED.
And in India two doors have opened: the Liberalised Remittance Scheme, under which a resident may remit up to USD 250 thousand, and Indian mutual fund schemes that invest overseas — including S&P 500 and Nasdaq 100 funds available in rupees, which need no remittance at all.
Insurance bought for tax — the umbrella chosen for its colour
A man goes to buy an umbrella in May. The shopkeeper shows him two. One is large, plain and strong. The other is small, pretty and matches his bag. He buys the pretty one because it matches.
In June it rains, and he gets wet.
He did not buy a bad umbrella by accident. He bought it on the wrong criterion — and the criterion he used had nothing to do with rain.
The workbook is blunt about the Indian version: AT LEAST 3 GENERATIONS OF INDIANS HAVE GROWN UP ON A DIET OF BUYING INSURANCE FOR TAX SAVING ALONE. AS A RESULT, THEY END UP BUYING THE WRONG KIND OF INSURANCE AND/OR COMPLETELY INADEQUATE INSURANCE.
Both failures, and they are different. Wrong kind — an endowment policy where term cover was needed. Inadequate — a Rs 5 lakh sum assured protecting a family that needs Rs 1 crore. A person choosing by Section 80C limit will stop at Rs 1,50,000 of premium, because that is where the tax benefit stops. The family's actual need does not stop there.
The workbook restores the correct order: appropriate and adequate insurance is the FIRST STEP of any good financial plan. TAX SAVING THROUGH THE INSURANCE PREMIUM JUST REDUCES THE COST of a good insurance plan.
And it states the comparison plainly: the ultimate return from investing the same sum of money into buying a TERM POLICY PLUS INVESTING IN PUBLIC PROVIDENT FUND will INVARIABLY BEAT the ultimate return from buying an ENDOWMENT life insurance product for the same amount of investment.
Twelve funds that are one fund — the thali ordered four times
A man worried about a limited diet orders four thalis from four different restaurants. He now has four plates of dal, rice, two vegetables and roti. He has four times the quantity and exactly the same variety.
The workbook describes the portfolio version exactly: if the investor buys 2 LARGE CAP FUNDS, 4 MID-CAP FUNDS AND 6 SMALL CAP FUNDS for diversifying his risk, HE CAN ACHIEVE SIMILAR DIVERSIFICATION BY SIMPLY BUYING A TOP 500 SHARES INDEX FUND.
Twelve funds. Hundreds of underlying stocks, mostly the same stocks. Twelve sets of statements, twelve sets of capital gains computations at redemption, twelve decisions at every review — and the diversification of one index fund.
The principle is stated in one line: DIVERSIFICATION DOES NOT COME FROM BUYING MANY SECURITIES. It comes from owning things that behave differently. Buying more of the same thing under twelve different names is duplication wearing the costume of diversification.
The workbook is careful to name the opposite error in the same breath: conversely, some investors will have their ENTIRE INVESTMENT PORTFOLIO IN A COUPLE OF SPECIFIC SECURITIES OR INVESTMENT WITHOUT ADEQUATE DIVERSIFICATION across asset classes or within an asset class.
So the adviser is not pushing in one direction. The task is to find THE GOLDEN MEAN for an appropriately diversified investment portfolio, BASED ON THE CLIENTS' RISK PROFILE, AVAILABLE RESOURCES AND TIME FRAME FOR GOALS — three inputs, and the right number of holdings falls out of them rather than being a target in itself.
Overconfidence — the office where everyone is above average
The workbook offers a test anyone can run. Survey the employees in a workplace and ask which percentile of relative performance they place themselves in.
MOST EMPLOYEES WILL PUT THEMSELVES ANYWHERE AROUND 60-75 PERCENTILE, WITH A RARE INDIVIDUAL CLAIMING TO BE BELOW THE 50 PERCENTILE.
Now count. By definition, exactly half of any group is below the fiftieth percentile. If almost nobody places themselves there, the answers cannot all be true. The workbook says so in a phrase worth remembering: THE AGGREGATE OF THESE EMPLOYEE PERCEPTIONS IS AN ARITHMETICAL IMPOSSIBILITY. THUS, THE TRUTH IS INDIVIDUALS CONSIDER THEMSELVES AS BETTER THAN THEY REALLY ARE.
This is a beautiful piece of reasoning because it proves the bias without examining a single individual. No one employee can be shown to be wrong. The distribution can.
In investing it appears as attributing skill to bets that have come off. The workbook's example: the client made a small bet on an individual stock that became a 5X in 3 months. THIS MAY ONLY PARTLY BE DUE TO SKILL AND MOSTLY BE LUCK. IN ANY CASE, EVEN IF IT IS SKILL, IT IS DOUBTFUL IF IT IS CONSISTENTLY REPEATABLE.
Note the two-stage argument — it is more careful than a simple accusation of luck. Stage one: it was probably luck. Stage two: even if it was skill, can it be repeated? A client can dispute stage one forever. Stage two is much harder to answer, and it is the question that actually matters for the next investment.
The danger that follows is concrete: the client may be tempted to OVER-INVEST in an asset class or security and MODIFY THE EXISTING ASSET ALLOCATION. And the workbook gives the adviser their finest sentence: in times like these, THE INVESTMENT ADVISER'S INFLUENCE CAN STAND BETWEEN THE CLIENT AND HER BIG MISTAKE.
Prioritising goals — the education loan the mother had not considered
A widow with a daughter in class twelve has Rs 42 lakh. Her daughter's engineering degree abroad will cost roughly Rs 40 lakh. Her own retirement is nineteen years away.
Ask her and there is no contest. "My daughter's education first. My retirement can wait." She is not being irrational — she is being a mother.
The workbook describes this exact situation: the client is emotional about making sure her daughter gets the best possible education EVEN IF IT MEANS COMPROMISING WITH HER RETIREMENT, which may be some distance away, and hence is not that important for her immediately.
Notice the two things making retirement lose: it is distant, and it is therefore felt as not important. Neither is a statement about how much money she will need at 62.
The adviser's job here is not to argue that education matters less. It is to do two things the workbook names: point out THE EXTENT OF THE COMPROMISE that is being done for a vital goal like retirement, and point out ALTERNATIVES LIKE PARTIAL EDUCATION LOAN for the higher education WHICH CAN THEN BE PAID BY THE DAUGHTER FROM HER EARNINGS after completion of the education course.
The second point is the one that dissolves the conflict. The mother framed it as a choice between her daughter and herself. It was never that choice. A partial loan, serviced later by a working engineer earning well, funds the degree without emptying the retirement corpus — and spares the daughter a future in which she must support a mother who has no pension.
The workbook's summary is the professional standard: this kind of OBJECTIVE ROLE played by the Investment Adviser is crucial in assisting the clients to TAKE THE RIGHT DECISIONS EVEN AS THEY ARE HIGHLY EMOTIONAL.
Key terms in this chapter
- Action bias
- The human need to do something, which runs against the long term consistency and long years of patience that investing requires.
- Antidote for home country bias
- The adviser must get educated on the benefits and opportunities in global investing and in turn educate their clients about the same.
- Attributing skill to bets that came off
- How overconfidence manifests in investing. A small bet that became a 5X in three months may only partly be due to skill and mostly be luck, and even if it is skill, it is doubtful if it is consistently repeatable.
- Buying insurance for tax saving
- A bias in which insurance is selected for the deduction alone. At least three generations of Indians grew up on this, and as a result they end up buying the wrong kind of insurance and or completely inadequate insurance.
- Chasing past performance
- Investing in last year winners, whether asset classes or specific securities, assuming what did well last year will do so again.
- Cool and calming influence
- The quality the workbook says is a must in the adviser as the client wrestles with the emotional upsurge caused by market cycles, ensuring the client continues on the journey planned in advance.
- Correct order for insurance
- Appropriate and adequate insurance is the first step of any good financial plan. Tax saving through the insurance premium just reduces the cost of a good insurance plan.
- Credit cards and impulsive spending
- The workbook states that using a credit card is not a good thing for most people, as credit cards induce impulsive spending.
- Cure for the tax-saving insurance bias
- Highlight the need for adequate pure insurance products and the poor returns from investment cum insurance products compared with equivalent investments combined with pure insurance plans.
- Dilution in risk management
- The danger that a client, made overconfident by a bet that materialised, may over-invest in an asset class or security and modify the existing asset allocation, dismantling the risk framework itself.
- Framing and risk tolerance questions
- Different investors react differently to triggers. One client prefers knowing what can be gained by following a pattern, another what is lost by not following it. In both cases the adviser is justifying the same recommended investment pattern, but the framing decides whether the client is convinced.
- Framing preference tools
- Specific tools are available that report on what kind of framing a client prefers, and that diagnosis is to be reconfirmed through discussions with the client.
- Global indexes as Indian schemes
- Global indexes such as the S&P 500 and Nasdaq 100 are now available as Indian mutual fund schemes, allowing rupee investment in overseas securities.
- Golden mean
- The appropriately diversified portfolio the adviser must find, based on the client risk profile, available resources and time frame for goals.
- Greed and fear cycle
- Most clients go through a cycle of greed and fear. Over exuberance can goad the client into taking rash decisions, or overarching fear can freeze the client.
- Highly concentrated portfolio
- The opposite error, where the entire portfolio sits in a couple of specific securities or investments without adequate diversification across asset classes or securities within an asset class.
- Home country bias
- The preference of most investors for securities available in their home countries due to familiarity with the markets, the companies involved and the regulatory environment, which denies them the diversification benefit of asset classes that do not move in tandem with local securities.
- Investment turning into trading
- The impact of too many and too frequent transactions. The activity changes character even though the assets may be similar.
- Liberalised Remittance Scheme
- The scheme under which a resident of India can remit up to USD 250 thousand for investments outside India. It has spurred the interest of Indian investors in foreign securities.
- Maximum exposure limit within an asset class
- A cap on how much may be held in a specific security within a given asset class, the counterpart of the asset class upper limit.
- Nudging through advance ground rules
- Laying down advance ground rules that the client buys into allows the adviser to have built in nudges for the client to follow.
- Objective role of the adviser
- The quality that is crucial in assisting clients to take the right decisions even as they are highly emotional.
- Partial education loan
- The alternative the workbook names for the education versus retirement conflict. The loan funds part of the higher education and can then be paid by the daughter from her earnings after completion of the education course.
- Paul Samuelson on investing
- The Economics Nobel Laureate said investing should be dull, not exciting, more like watching paint dry or grass grow, and that if you want excitement you should take USD 800 and go to Las Vegas.
- Percentile survey
- Surveying employees on which percentile of relative performance they place themselves in. Most put themselves around the 60 to 75 percentile, with a rare individual claiming below 50, an aggregate which is an arithmetical impossibility.
- Prioritising goals
- The adviser role where resources are not sufficient for meeting all goals. The adviser points out the extent of compromise being done to a vital goal like retirement and points out alternatives.
- Reasons for not investing overseas
- Beyond familiarity and comfort: lack of knowledge of opportunities abroad; home country laws that may prevent investing outside India; lack of access and high cost of access; compliance with the tax and other laws of the other country which may conflict with local laws; and lack of expert advice as the advisers themselves are not well versed.
- Retail therapy
- A situation where a person goes on a shopping or buying binge in order to reduce stress.
- Reversal to the mean
- Most asset classes have a cycle of growth and decline, and there is an inevitable reversal to the mean, which is why buying last year winner frequently means buying at the point of maximum disadvantage.
- Self-imposed brake
- A restraint on behaviour that comes from an in-built expense limit rather than from willpower. In extreme cases a separate account is opened holding the budgeted amount, spent only through a debit card or by withdrawing cash.
- Self-limiting behaviour
- The design principle of this chapter. The adviser role lies in understanding stress-driven impulses and providing ways to make sure that such behaviours are self-limiting, rather than relying on the client willpower at the moment of temptation.
- Term plus PPF versus endowment
- The ultimate return from investing the same sum into a term policy plus Public Provident Fund will invariably beat the ultimate return from buying an endowment life insurance product for the same amount of investment.
- Three stages of a stress behaviour
- It first provides a good feeling and relief from stress; in moderation it is good and takes the sting out of emotional stress; but it rarely stays moderate and invariably leads to more stress in the future as the economic impact kicks in.
- Too much diversification
- Holding so many securities that the investor finds it impossible to manage the investments. Diversification does not come from buying many securities; it can come simply by buying an index representing that asset class.
- Upper limits for each asset class
- A pre-decided asset allocation policy with upper limits for each asset class, which makes sure overexposure to a specific asset class is avoided.
