Most distributors quote "1-year returns" from a marketing flyer and stop there. The good ones read factsheets like analysts and can decompose a return into risk-adjusted, benchmark-relative, and time-period-honest figures. This chapter teaches you those tools — the practitioner's shortlist of metrics that survive the marketing layer.

Foundation

Returns matter, but so does the risk taken to earn them. Standard deviation measures total volatility. Beta measures sensitivity to market moves. Alpha measures excess return over risk adjustment. Sharpe ratio = (return − risk-free) / standard deviation; higher is better. Benchmarking compares fund return to a relevant index — for large-cap, NIFTY 100; for mid-cap, NIFTY Midcap 150. Comparing a mid-cap fund to NIFTY 50 is meaningless. Performance must be evaluated over multiple time-frames (1y, 3y, 5y, 10y) — not just the one that flatters the fund.

Deep Dive

Practitioner-grade analysis: read the Annual Report. Look at the rolling 1-year, 3-year, 5-year returns vs benchmark. A fund that beat NIFTY by 2% over 1 year but lagged over 5 years has had a recent rally — not sustained skill. Standard deviation: equity fund typical 15-22% annualised. Beta: large-cap ~1.0; mid/small-cap can be 1.2-1.5. Information ratio: alpha / tracking error — measures consistency of out-performance. Look at downside-capture ratio (does the fund fall less than the benchmark in down markets?) — equally important as upside capture. SPIVA India scoreboards (S&P) publish active-vs-passive performance — most active large-cap funds have underperformed NIFTY 100 over 5-10 year periods.

Advanced

Avoiding the marketing trap: most factsheets emphasise SI (Since Inception) returns or short-window returns that flatter the fund. Always demand rolling-return windows (e.g., rolling 5-year over the last 10 years) to see consistency. Survivorship bias: failed funds are merged or wound up; only survivors remain in databases — actual industry returns are lower than survivor-only returns suggest. Selection bias: reading only one fund's factsheet vs reading the category cohort tells you whether outperformance was skill or category tide. Sophisticated distributors maintain peer-group performance dashboards — typically 5-10 funds per category — for comparable analysis.

Common mistakes & pitfalls
  • Quoting only 1-year returns — short-window noise.
  • Comparing fund return to wrong benchmark (mid-cap fund vs NIFTY 50).
  • Ignoring standard deviation and downside capture.
  • Confusing "Since Inception" with "10-year average".
  • Cherry-picking time periods that flatter the fund.

Frequently asked

What is a "good" Sharpe ratio for an equity fund?
Indian equity fund Sharpe ratios typically range 0.3-0.6 over 5-10 year periods. >0.5 is strong; >0.7 is exceptional and rare. Benchmark NIFTY 100 has historically had Sharpe ~0.4. A fund needs Sharpe > benchmark Sharpe to truly add risk-adjusted value.
Why do active funds underperform indexes over long periods?
Three reasons: (1) higher TER drag — 1-1.5% annual cost compounds; (2) market efficiency — large-cap Indian equity is reasonably efficient; (3) survivor bias in indices — the index automatically replaces declining stocks, while a stuck-with-loser fund cannot. Mid-cap and small-cap funds can outperform — those segments have less coverage.
What is rolling return?
Rolling return measures returns over fixed periods (e.g., 5 years) starting from each available date. So a 10-year history with rolling 5-year periods gives you 5 overlapping 5-year returns. This eliminates the cherry-picking of any one starting date and shows consistency of returns across time.

Practice questions

Q 1
Sharpe ratio measures:
  1. (a)Total return
  2. (b)Risk-adjusted excess return per unit of total risk
  3. (c)Beta-adjusted return
  4. (d)Volatility
Correct: (b) Risk-adjusted excess return per unit of total risk
Sharpe = (return − risk-free) / standard deviation. Measures excess return per unit of total risk taken.
Q 2
A fund with downside-capture ratio of 80% means:
  1. (a)The fund matches the benchmark in down markets
  2. (b)The fund falls 20% less than the benchmark in down markets
  3. (c)The fund returns 80% of what the benchmark does
  4. (d)The fund has 80% equity allocation
Correct: (b) The fund falls 20% less than the benchmark in down markets
Downside-capture of 80% means the fund falls 80% as much as the benchmark in down markets — i.e., 20% less. Lower is better.
Q 3
A multi-cap fund should be benchmarked against:
  1. (a)NIFTY 50 only
  2. (b)NIFTY Midcap 150
  3. (c)NIFTY 500 or NIFTY 200 (broad-market)
  4. (d)BSE Sensex
Correct: (c) NIFTY 500 or NIFTY 200 (broad-market)
Multi-cap funds invest across cap segments — appropriate benchmark is NIFTY 500 or NIFTY 200 TRI. NIFTY 50 (large-cap only) is mismatched.
Q 4
Standard deviation in the context of mutual funds is:
  1. (a)A measure of return
  2. (b)A measure of total volatility around the mean return
  3. (c)A measure of beta
  4. (d)The fund's expense ratio
Correct: (b) A measure of total volatility around the mean return
Standard deviation measures total volatility — how much returns deviate around their average. Higher SD = more uncertainty in any given period's return.
Q 5
Survivorship bias in mutual fund performance data refers to:
  1. (a)Funds that survive longer have better managers
  2. (b)Failed funds disappear from databases, inflating average performance of survivors
  3. (c)Investor survival depends on diversification
  4. (d)Long-term funds always survive
Correct: (b) Failed funds disappear from databases, inflating average performance of survivors
Survivorship bias: failed/merged funds drop out of data, leaving only survivors. Industry-wide reported returns thus overstate what an investor would have actually achieved.
