Risk & Risk-Adjusted Return

Beta

Beta measures how much a fund moves relative to its benchmark - above 1 means it amplifies market moves in both directions, below 1 means it dampens them. Beta alone says nothing about skill, only about market sensitivity.

What is Beta?

A beta of 1.0 means a fund moves in lockstep with its benchmark. A beta of 0.6 means it typically moves about 60% as much - smoother in both up and down markets. Beta measures sensitivity to the market, not quality: a low-beta fund can still have zero skill, and a high-beta fund can still have real alpha.

FORMULA

β = Cov(Rp, Rm) / Var(Rm)

RpFund’s returns over time
RmBenchmark’s returns over the same periods
CovCovariance between the two return series
VarVariance of the benchmark’s returns

Beta is about sensitivity to the market, not skill - that’s what alpha measures separately.

CHART

Beta vs Alpha - 6 real funds

Every fund here runs below-market beta (all under 1.0). Beta position alone doesn't predict alpha - the highest-alpha fund isn't the highest- or lowest-beta one.

WHAT THIS MEANS FOR YOU A low beta isn’t automatically “safer” in a way that matters, and a high beta isn’t automatically “riskier” in a way that costs you - check alpha and Sharpe Ratio alongside beta, never beta alone.

METHODOLOGY Beta and alpha both computed over a trailing 3-year window as of 2026-08-31, against each fund’s own benchmark. Data: Punji risk analytics. Not investment advice.
