Why You Need a Buy-and-Hold Benchmark

A strategy's return says nothing by itself. Is plus ten percent good or bad? The answer depends on what doing nothing would have returned over the same stretch, and that is exactly what a benchmark answers.

What a buy-and-hold benchmark is

The simplest benchmark is to buy at the start of the sample and hold to the end, doing nothing. It is the null hypothesis of active trading: if your system does not beat inaction, the work of building it did not pay off. The comparison must run on the same data, over the same period and with the same costs, or it means nothing.

Our benchmark on the same data

Holding a position across 518 daily bars for each of 12 pairs, with the same costs as every other run, returned a median of 4.79% with 9 profitable pairs out of 12. That is the bar an active rule has to clear to justify existing.

We ran ten classic rules on the same data. Not one beat the median return of holding — including the best of them. Every run is published with its limitations: the golden cross, Fibonacci retracements, the Donchian channel and the rest.

Where the comparison turns dishonest

Three common substitutions. Comparing returns while ignoring risk: a system with the same profit and twice the drawdown is not equivalent to holding. Comparing different periods, picking a favourable stretch for the strategy. And the subtlest: holding works in one direction only while an active system trades both, so a direct return comparison always carries a caveat — it is more honest to look at risk-adjusted return and drawdown together.

When losing to the benchmark is acceptable

There is one case. If a system delivers a materially smaller drawdown and less time at risk, its lower return can be a sensible trade. A strategy in the market a tenth of the time earning half of buy-and-hold is superior per unit of capital at risk. But that has to be calculated and stated up front, not used as an excuse afterwards.
