Expected Return

Expected return is the average outcome an investor anticipates from an asset, computed as the probability weighted mean of its possible returns. An asset with a 60 percent chance of gaining 20 percent and a 40 percent chance of losing 10 percent has an expected return of 8 percent. It is the central input, alongside risk, in portfolio construction.

Why it matters

Every allocation decision is an implicit expected return forecast, and the number is easy to abuse. Historical averages get projected forward as if regimes never change, and a high expected return can hide catastrophic paths: an asset that usually doubles but sometimes goes to zero may be unholdable in practice despite attractive arithmetic. Serious practitioners pair the mean with distributional questions, volatility, skew, drawdowns, and correlation with the rest of the portfolio, and they distinguish arithmetic from geometric averages, since volatility drags compounded results below the simple mean.

In the gold vs bitcoin debate

Neither gold nor bitcoin produces cash flows, so their expected returns cannot come from discounting earnings; both rest on monetary theses. Gold's base case is roughly tracking inflation over long horizons, with episodic surges during monetary stress, a modest mean with defensive properties. Bitcoin's advocates argue for a much higher expected return from continued monetization toward or beyond gold's roughly 20 trillion dollar market value, while skeptics assign meaningful probability to severe loss. The honest framing is that bitcoin offers a wider distribution around a disputed mean, and gold a narrower one around a modest mean.
