Small Cap Fund Risk Metrics — Complete Guide

Why risk metrics matter more in small caps

Any fund can look brilliant in a bull market. The metrics on this page reveal what happens in a correction — how hard the fund falls, how quickly it recovers, how consistent the manager is, and whether that performance was skill or just market tailwinds. These are the numbers that experienced investors read before the ones on the factsheet.

Risk-Adjusted Return Metrics

These metrics normalise a fund's return by the risk it took to earn it. Two funds with identical returns can have very different risk profiles — these ratios reveal that difference.

Most Used

Sharpe Ratio

Return earned per unit of total risk (standard deviation). The most widely used risk-adjusted return metric. Best for comparing funds of the same category.

Better for Small Caps

Sortino Ratio

Like Sharpe but only penalises downside volatility. More appropriate for small cap funds where large upside months are common and shouldn't count against the fund.

Portfolio Context

Treynor Ratio

Return per unit of systematic (market) risk using Beta. More relevant when evaluating a fund as one component of a larger diversified portfolio.

Manager Skill Filter

Information Ratio

Measures how consistently a fund manager outperforms the benchmark — not just by how much, but how reliably. The best filter for separating skill from luck.

Volatility & Market Sensitivity

These metrics measure how much a fund moves — both in absolute terms and relative to the market benchmark. They tell you how bumpy the ride will be.

Core Volatility

Standard Deviation

How much a fund's monthly returns vary around its average. The fundamental measure of how volatile — how bumpy — a fund's return journey actually is.

Market Sensitivity

Beta

How much the fund moves for every 1% move in the benchmark index. Beta of 1.2 means the fund amplifies market moves by 20% — in both directions.

Worst Case Reality

Max Drawdown

The largest peak-to-trough decline the fund has ever experienced. The most honest measure of real investor pain — and what causes panic redemptions at market bottoms.

Benchmark Relationship Metrics

These measure the relationship between a fund and its benchmark — revealing how much the manager is actually doing versus how much the index is doing for them.

Manager Value-Add

Alpha

The return earned above and beyond what market risk (Beta) would predict. Genuine Alpha means the manager added value through stock picking — not just riding the bull market.

Closet Indexer Check

R-Squared

Percentage of fund returns explained by the benchmark. Very high R² in a small cap fund is a red flag — you may be paying active fees for index-like performance.

Structural Portfolio Risks

These risks are not captured in any single number — they live in the portfolio's construction. Ignored by most investors. Responsible for some of the worst outcomes.

The "Diversification" Trap

Correlation Risk

The danger of holding multiple funds that move together in a crash. Owning five small cap funds may feel diversified but typically provides zero protection when all fall simultaneously.

Portfolio Construction

Concentration Risk

Too much exposure to one stock, sector, or theme. In small caps, a 7% position in a single stock that falls 25% hits fund NAV by 1.75% in a single day.

Often Ignored

Liquidity Risk

Can the fund actually sell its holdings when investors redeem? The larger the fund, the harder this becomes. India's biggest small cap funds hold positions representing 5–10% of some stocks' market cap.
