Short-bias Strategy
A directional strategy in which the manager holds both long and short positions but keeps a net short exposure to the broad market, so the fund benefits when the market falls.
In plain language
Most funds make money when markets rise. A short-bias fund is built the other way round.
The workbook classes it as a type of Directional Strategy. The manager takes both long and short positions in selected stocks or a broad-based market index, but maintains a net short exposure to the broad market. Because of that net short tilt, a short-bias strategy benefits from a downward movement in the market.
The word "bias" is doing real work. The fund is not purely short — it may own stocks it likes — but taken together its shorts outweigh its longs.
How it works
How it differs from its neighbours (7.1.4)
| Strategy | Positions allowed | Net exposure |
|---|---|---|
| Short-bias | Long and short | Always net short |
| Long-only | Long | Net long |
| Long-short | Long and short | May be net long or net short (a typical 130/30 is net long) |
| Dedicated-long | Exclusively long | Net long |
| Market-neutral | Long and short | Aims for portfolio beta near zero |
As a directional strategy, short-bias does not aim for a portfolio beta of zero; it takes a view on market direction.
Risk. The workbook warns that directional and short-bias strategies may be volatile and risky during major macro-economic upturns as well as downturns, depending on the net exposure the manager has taken. For a short-bias fund, a sharp rally is the danger.
How to spot one. Add up long and short positions segment by segment. If short exceeds long across the book, the fund is net short — short-bias.
The formula
Net exposure = Value of long positions − Value of short positions
Net exposure < 0 across the broad market → short-bias
A worked example
Workbook Example 4 (Chapter 7) — Fund LMN, positions on 1 April 2023
| Segment | Buy | Sell | Net |
|---|---|---|---|
| Large-cap | Company C: 2,00,000 × Rs 250 = Rs 5 crore | Company D: 2,00,000 × Rs 500 = Rs 10 crore | (Rs 5 crore) |
| Mid-cap | Company E: 1,00,000 × Rs 500 = Rs 5 crore | Company F: 1,50,000 × Rs 500 = Rs 7.5 crore | (Rs 2.5 crore) |
Total long = Rs 5 crore + Rs 5 crore = Rs 10 crore
Total short = Rs 10 crore + Rs 7.5 crore = Rs 17.5 crore
Net = Rs 10 crore − Rs 17.5 crore = (Rs 7.5 crore) → net short
The workbook's verdict: Fund LMN is pursuing a short-bias strategy, being net short in both large-caps and mid-caps.
Illustrative extension — simplified by assuming every position moves exactly with the market.
Market falls 10%: gain ≈ 10% × Rs 7.5 crore = + Rs 75 lakh
Market rises 10%: loss ≈ 10% × Rs 7.5 crore = − Rs 75 lakh
The long positions in C and E soften both outcomes, but cannot reverse them while the book stays net short — which is why a strong rally is the strategy's main risk.
Why NISM asks about it
Chapter 7 (Category III AIF Investment Strategies and Due Diligence Process) defines short-bias within 7.1.4 (Directional and Short-bias Strategies) and tests it through Example 4, where Fund LMN must be identified from its positions. Expect identification questions from a table of trades and comparisons with long-only and long-short strategies.
Common exam traps
- Short-bias holds longs as well as shorts — it is not a dedicated-short strategy.
- It must be net short; a long-short fund may be net long or net short.
- Long-only is net long; short-bias is net short — the workbook's own contrast.
- It is directional, so it does not target zero beta like market-neutral.
- Risky in upturns as well as downturns, depending on net exposure — a rally hurts a net-short book.
- A dedicated-short strategy that "exclusively takes buy positions" is a false statement in the Chapter 7 sample questions; exclusive buying is dedicated-long.

- Directional StrategyA Category III AIF strategy that takes a net long or net short position on stocks or an index, betting on the market's direction; short-bias and dedicated-long are its variants.
- Long-only Equity StrategyA Category III AIF strategy that takes only buy positions in selected stocks when investing, aiming at absolute returns over the medium to long term with a strong emphasis on capital preservation.
- Long-Short Equity StrategyA Category III AIF strategy that buys stocks the manager thinks are under-priced and shorts those it thinks are over-priced — often run as a 130/30 fund with 100% net market exposure.
- Market-Neutral StrategyA Category III AIF strategy taking equal long and short exposures within a sector, industry or market-cap segment so that portfolio beta is zero or close to zero.
