How it works

One rule.
Four names. No opinions.

01Month-end screen

Every company whose latest call passed the quality checks and whose shares sit in the bottom third of 12-month performance goes into the pool, ranked by the model.

02Four names, fixed

One held twelve months, three held six. Equal amounts, no leverage, no trading in between. The list is locked before the buy price is known.

03Scored against the index

Each pick is measured from its month-end price against the S&P 500 over the same days. Mean, median and hit rate, together.

04Losers stay on the board

The scorecard below is the whole history. The worst pick this year is on it, not in a footnote.

The lab behind the list.

Every earnings call since 2016 gets the same 500 yes-or-no checks, 30 lab markers and a grade, measured against 174,989 other calls. The picks come from this; so does every stock page.

Every pick, every month, graded in public.

Past months are open. Each pick is measured from its month-end price against the S&P 500 over the same days. We show the median and the hit rate next to the average, because the average alone would flatter us.

Read the shape before you buy. Most picks lose to the index. A few multiply, and they carry the whole list. That is the edge this rule harvests, which is why it holds all four stocks for the full term and never sells a winner early. Months before Mar 2026 had only the twelve-month pick. Lists before this one were generated after the fact by the fixed rule; from October 2026, each month's four are published before their buy price is known.

Chart from the study on AI mentions
Research No. 1

We counted “AI” on 174,989 earnings calls. Then we waited a year.

We counted the word on 174,989 calls since 2016, then followed 22,240 of the stocks for a year. The odds of beating the S&P 500 rose with the count, from 29% to 38%. The median stock still lost. And the companies that suddenly discovered the word did worst of all.

What we claim, and what we don't

A rule you can audit, not a hunch you have to trust.

The picks come from a rule, fixed before we buy.

Four stocks a month, published before their buy price is known, scored against the S&P 500 with the median and hit rate shown. Losers stay on the scorecard. How we killed 1,600 strategies before keeping this one

A grade is not a forecast.

The call grade describes the conversation: candor, specificity, what was dodged and what was underwritten. Only the Monthly Four carries a buy, and only as a set of four. How the grade is built

Its weakness, up front.

A rule that buys fallen stocks suffers in a slow grind-down bear market. In 2018-style conditions it lost 17% to the index. If you cannot hold through a year like that, these picks are not for you.
