BrainStock calls the market.
And grades itself in public.

Every market morning a ranking model scores 330+ stocks against each other on 7 published signals and publishes 15 buys and 15 avoids. Five trading days later each one is graded against SPY, building an un-cherry-picked track record. Type any ticker below to see where it ranks today.

Step 2 · The brain's book

We handed the brain $10,000.

Every graded call becomes an equal-weight position. The wins and the misses compound below, marked to real closes. Nothing hidden, nothing reset.

The first calls are in flight, the scoreboard fills itself as they resolve.

Step 3 · How it works

The ranking, and the grading loop.

No black box: 7 published signals, one ranking after every close, and every call graded against SPY. How each signal is built, and what the tests did and didn’t show, is on the methodology page.

01
7 signals
Last week’s and last month’s move against the stock’s sector, the latest earnings and how the stock reacted, earnings due next week, seasonality, and short-term momentum weighted by turnover.
02
Ranked, not priced
After each close all 330+ stocks are scored against each other, within their sectors and balanced for market risk. The top 15 become buys, the bottom 15 avoids. No price targets.
03
Graded against SPY
A buy hits if it beats SPY over the next 5 trading days, an avoid if it lags. Each call is logged before the open and never rewritten.
Step 4 · Losses, absorbed

Every miss gets an autopsy.
Every night, a lesson.

Most models hide their losers. This one opens them up: the stored evidence behind each missed call, and the nightly training run where the net absorbs every graded outcome. The flywheel, on the floor, in public.

The training floorNightly · after grading

The first training run prints here after tonight's grading pass. The net only learns from calls that have been graded against real closes, so the floor opens when the receipts do.

Second desk · the book net

A second net is in school: it learns P(drawdown) from every Risk Desk scan once the book's 63 sessions run out. 0 of 40 books matured. Feed it your book →
