SELL calls, withdrawn

The model no longer publishes sell calls. Too few of them ever reached a graded 4-week outcome to show whether they worked, so we stopped publishing them rather than keep running something we cannot stand behind. The most recent of the calls published before that change are below. They stay here, with their results, because nothing in this log is edited after the fact.

Before the log

The backtest that earned publication

Signals only ship because the model survived two rounds of testing: a point-in-time replay of ~2 years of real market data (100 weekly cohorts, no hindsight), then a stricter pass graded against real completed sales. The stricter pass decides what publishes, fees caveat included.

+5.4pp

Published buys beat the market

Excess return vs all tracked sport cards over the following days, measured on real completed sales after our data-cleaning passes (t = 3.2). Our top-scoring tier measured stronger still (+9.0pp, t = 4.4). We withdrew that tier for a month when contaminated sale data made it read negative; after removing the contamination and re-testing, it publishes again.

~0pp

After fees: not distinguishable from zero

The same testing puts the absolute return after a typical 13% round trip of selling fees within noise of zero (t below 1). We publish signals to help you buy at the right price, not as a profit system, and every call is logged before its outcome is known.

Signals are informational only, not financial advice. Prices are trailing medians of live market prices; your fills, fees, and timing will differ. Past performance, in the log or in the backtest, does not guarantee future results. Buy signals are a Pro membership feature; this page exists so you can judge them before paying.
