Does Point & Figure Charting (X's and O's) actually work?
MARGINALReal but small -- not worth what it costs to run.
The claim
The double-top buy / double-bottom sell signals time the market better than holding — Charting tradition / Dorsey Wright
What we did
Tested against Buy & hold SPY / honest reconstruction.
The result
Result: Long 1960-2026: +6.8%/yr vs buy-hold +7.5%, maxDD -38% vs -57% (3% box, Sharpe 0.59 vs 0.53)
Long 1960-2026: +6.8%/yr vs buy-hold +7.5%, maxDD -38% vs -57% (3% box, Sharpe 0.59 vs 0.53)
Verdict
Point & Figure is trend-following in costume. Going long its double-top buy signals and flat on the double-bottom sells, it gives up ~1%/yr of return for a meaningfully smaller drawdown (-38% vs -57%) and a hair better Sharpe -- real risk reduction. But a plain 10-month moving average does the SAME job better (it halves the drawdown; P&F only trims a third). The X's and O's add ceremony, not edge -- and bigger boxes (3%) beat small ones by whipsawing less.
