Do catalyst types predict excess return?

Every detected catalyst is graded against what the stock actually did over the following 60 trading days, measured as excess return versus SPY so a rising market does not flatter the result.

⚠️ Read the symbol-demeaned column. The raw column is dominated by which symbols happen to carry a catalyst type — per-symbol excess spans roughly +112% to −51%, so a type concentrated in strong names looks predictive whatever the catalyst was. Subtracting each symbol's own mean removes that.

Catalyst typeRawSymbol-demeanedn (events)
earnings+17.76%+2.10%138
partnership+9.24%+0.18%204
regulatory-16.20%+0.10%55

contract-5.53%-5.11%86
product+5.26%-5.24%48
macro-0.99%-7.70%8
insider-6.82%-16.82%11
Verdict: no catalyst type is tradeable on this evidence. The largest demeaned effect is earnings at +2.10% (n=138, 658 events total) — inside noise for a sample this concentrated. Most of the apparent signal in the raw column is symbol beta.

Strategies we tested and rejected

A published negative result is worth more than an unpublished positive one. These are our own ideas, tested against a pre-registered bar and reported as they came out.

Triple-EMA trend score (the signal behind our own trend charts) — FALSIFIED

We tested the signal that generates the trend charts on this site: does trading it beat simply holding the same instrument? Two directions were pre-registered before running — trend-following and contrarian — against a gate of beating buy-and-hold in 6 of 8 standard market periods.

Evidence. SPY: 2/8 trend-following, 0/8 contrarian. Across all 58 published ETFs, 116 arms were tested and exactly 1 cleared the gate — while chance alone predicts about 16.8. An earlier count of 31 'winners' collapsed once we required a period to be profitable and not merely better than a decaying inverse ETF: one arm scored 8/8 while making money in 0 of 8 periods.

Takeaway. The charts remain a useful picture of market state. Trading the score is not supported by the evidence, and we say so rather than quietly shelving it.
