Does Cheapest 100 by P/E (value) actually work?

DEAD

No edge left once tested on a fair footing.

The claim

Hold the 100 lowest-P/E stocks, equal-weight — Value investors everywhere

What we did

Tested against Cap-weight SPY, buy & hold, 2017-2026, 100-stock equal-weight, annual rebalance, survivorship-free.

The result

Result: 10.2 %/yr CAGR (cap-weight = +12.5)

+10.2%/yr CAGR, Sharpe 0.5, maxDD -61% (2017-21 +11/yr, 2022-now +10/yr)

Verdict

Value's lost decade, in one line: +10%/yr (below cap-weight) with a -61% drawdown. Buying cheap was a cold, honest rule that simply did not pay in 2016-2026.

What the test did and did not do
