AI-built quant · every trade public
Three strategies run live — short-term mean reversion and momentum, long-term trend following, and an earnings direction model. Each discloses a position when it opens and again when it closes, so the curve behind this is the whole curve. Drawdowns included.
Backdrop: cumulative per-trade return across 55 closed trades (07-31–08-15) — equal weight, a sum of trade returns, not a portfolio return.
Calls that worked
Gold marks where the book disclosed the entry, white where it announced the exit. These are the best four — the full record, losers included, is here.
The products
Each has its own page — how it's built, what it found, and what it's saying now.

又有人问我Fable是怎么预测财报的，我来泄露一下商业机密吧。 首先肯定不是你直接问Fable这个财报怎么看，这样做是没用的，虽然Fable拥有比我们所有人都多的知识，但是没有结构性的输入就不会有结构性的输出。
在 X 上看原帖 →Michael Burry重仓 11%仓位做空 $NBIS 今天遭到30%的暴涨。 在这种毁灭性轧空之下，MB决定加大做空仓位。 substack还能继续提供无限弹药吗？
在 X 上看原帖 →Jane Street 在 7 月 引起Situational Awareness 大崩溃中录得 150 亿美元亏损，几乎抹去了去年大牛市中获得利润的一半。 所以就连天天割散户韭菜的，地表最强大量化机构也在今年七月折戟。 所以我们度过了毁灭性的7月 迎来了充满希望的八月。
在 X 上看原帖 →Fable认为 $LITE 财报要上涨 $GLW 侧击还是 $LITX 直接轰入。
在 X 上看原帖 →$MU 的IV出现了崩溃式的下跌，今天不涨不跌，昨天买的期权都会自动减10% 这究竟是什么原因，是谁在拼命卖出 $MU 的期权。
在 X 上看原帖 →$MU 这种情况，就很容易引起严重的Gamma squeeze，这些人卖出的低价期权一下成了燃料罐。末日期权IV直接从70%飙升到接近100% 所以我们说目前这个期权价格是mis-price，后面他们肯定要修复的。

Markets around the clock
Friday 4pm the tape stops, and for 65 hours every app you own shows you a dead number. Meanwhile Tokyo trades, futures move, and by Monday’s open the gap has already happened — you just weren’t allowed to watch it.
This one forecasts nothing. It is a live board that never goes dark: cash index during US hours, CME futures overnight, and Hyperliquid perps at weekends — so there is a real price at 3am on a Sunday instead of a stale Friday close. Every number is an actual print from a named venue. Only tickers with a genuine 24/7 venue appear; nothing is invented to fill a gap.
SPX forecast
A forecast, and deliberately separate from the 24/7 board — that one reports prints, this one puts a distribution on tomorrow’s close. Six thousand Monte-Carlo paths, gamma-adjusted, anchored on the live option chain: where dealers damp or amplify moves, and the walls that tend to pin price.
A 68% band that contains the close 94% of the time is too wide, not “94% accurate”. The honest read is that the cone is currently conservative, and tightening it is open work. We publish the number either way.
The band published that morning, and where the index actually closed.

Earnings Radar
Published every Sunday for the week ahead. For each name reporting, the board compares the implied move priced into options against the typical move that stock has actually delivered on its last nine reports. When those two disagree, that is the trade.
Live predictions for the coming week, published before the reports. Verdict is the ratio of implied to typical: RICH means options cost more than the stock usually moves, CHEAP means less.

On every card the conclusion sits in the top-right badge — that is the whole read, and it comes in three colours: ■ 绿 BULLISH means the model expects up, ■ 红 BEARISH expects down, and ■ 灰 coin-flip means it has no edge and makes no call at all.
Only the red and green calls are counted below — the same threshold the card itself uses to print the badge, so the table can never disagree with the picture. The grey ones are not predictions and are excluded rather than quietly scored as free wins — a call the model declined to make cannot be right or wrong. Click any row to see the original card exactly as it was posted on X, before the report.

Structure Read
Not a price line. Zig-zag pivots, the break triggers on both sides, measured targets, the volume-at-price magnet profile on the right edge, and the read written out underneath. 6 names below are the full desk chart; all 79 covered tickers are searchable.
Research
Rebuilt from SEC's raw 13F filings rather than a vendor feed. Net flow is change in share count × quarter-end price — change in reported value just tells you the stock went up.
SEC filings are the original record, public before anyone writes them up. This study read 124 companies' own 10-Qs to find where the struck-down tariff refunds actually landed.
