Portfolio

Weighted Yield

Compare value-weighted against simple average yield to expose concentration.

Beginner

Introduction

Who this is for: Portfolio investors reporting blended performance.

Why it matters: A simple average of yields treats a £1m asset the same as a £100k one. The weighted figure is the only honest portfolio yield, and the gap between the two tells you how concentrated the portfolio is.

Typical scenario: An investor with four assets of very different sizes reporting portfolio performance.

Common mistakes:
  • Reporting the simple average because it usually looks better.
  • Weighting by cost rather than current value.
  • Ignoring that one large low-yielding asset dominates the blend.

The simple average (7.40%) overstates the portfolio by 1.34 points because the largest asset yields less than the smaller ones. The weighted figure of 6.06% is the correct one.
One asset is 62% of portfolio value. Its performance effectively is the portfolio's performance.
