Tested. Our top-⁠scored stocks returned 2.2x the average stock over the next month. How we tested it

Where every figure comes from.

Each company's SEC filings on EDGAR, read twice a day: its registration (Form S-1 or F-1), the amendment that sets its price range, and its final prospectus (424B4). The shares, the price, the underwriters, the lock-up, and the company's words are the filing's, linked on each line.
The expected day is Massive's IPO calendar's, the first trade the market data's, and the moves each stock's daily closes against its offer price.
The market cap is Breakaway's arithmetic: the shares the prospectus says will be outstanding after the offering, times the midpoint of the range or the offer price.
The Quality Score is Breakaway's, from a stock's second trading day; for its first 21 sessions it is marked New listing, and each check that needs more history waits for it.
Blank-check companies (SPACs) and unit offerings are left out and counted; a direct listing and a US listing of a company listed abroad are in and marked.
