Benchmarks & Alpha

Beating the market average

If your class average in an exam is 75%, scoring 80% means you performed well (positive alpha). Scoring 70% means you underperformed despite a "decent" mark. The benchmark is your class average.

Benchmarks & Alpha

What is a Benchmark?

A benchmark is an index that represents the market the fund invests in:

Fund TypeCommon Benchmark
Large CapNifty 50, Sensex
Mid CapNifty Midcap 150
Small CapNifty Smallcap 250
Flexi CapNifty 500
DebtCRISIL Composite Bond

Why Benchmarks Matter

If a large-cap fund returned 12% but Nifty 50 returned 14%, the fund actually underperformed. You would have been better off with a Nifty 50 index fund.

What is Alpha?

Alpha = Fund Return - Benchmark Return

  • Positive alpha: Fund beat its benchmark (fund manager added value)
  • Zero alpha: Fund matched its benchmark
  • Negative alpha: Fund underperformed (you're paying fees for worse returns)

The Harsh Reality

Over 5+ year periods, 80-85% of active fund managers fail to beat their benchmark after accounting for expenses. This is why index funds have become so popular — if most managers can't beat the index, why pay them to try?

When Active vs Passive Makes Sense

Active Works Better

  • + Mid & Small caps (less coverage, more mispricing)
  • + Credit risk debt (skilled managers spot good credits)
  • + Emerging/niche categories

Passive (Index) Works Better

  • - Large caps (heavily analyzed, hard to beat Nifty 50)
  • - Liquid/overnight funds (very little room for alpha)
  • - Core portfolio allocation

Key Takeaway

Always compare a fund's returns to its benchmark. A "good" return that trails the benchmark means you're paying the fund manager to do worse than a simple index fund. Alpha is what you're paying for.

Your Next Step

On our fund pages, benchmark comparison is built in. Check if your fund consistently beats its benchmark over 3-5 year rolling periods.

Mutual Fund investments are subject to market risks, read all scheme related documents carefully. Past performance is not indicative of future returns.
