Wyckoff: buying the accumulation beats buy-and-hold on LYV by +1.7 points a year over 21 years.
Findings derived from the full panel. Each carries its number and its denominator; the computations are reproducible with artifact 11e887f77aa5.
Mechanical approximation: 20-bar range with an 8-bar test window; active accumulation state → long; state lost → flat.
The verdict compares the strategy with buying and holding LYV over the same window, with round-trip costs per asset class. “Out of sample” is walk-forward: the rule is fit on one stretch and judged on the next. A result that beats in the full sample but not out of it is overfit. Full methodology in the protocol. How we test.
