Markets that snap back, and the schedule the trade actually demands
The setup wants markets where a full-range day is an emotional event rather than new information — which is a description of indices, and a warning about single stocks.
Key takeaway
- Index futures and large ETFs mean-revert after emotional days; thin single names trend on their news
- An 80-20 day caused by a real catalyst is information, and information follows through
- The routine is two short sessions: an evening scan for setup days, and the next morning around the low
Why the setup lives in index products
An index is an average, and averages mean-revert harder than their components. A full-range down day in an index future is usually a repricing of mood — positioning, margin, fear — spread across hundreds of names, and mood exhausts. The same day in a single stock is often a repricing of fact: a guidance cut, a downgrade, a product failure. Facts do not care that the range was stretched, and the next day's undercut keeps going.
| Market | Fit | Note |
|---|---|---|
| Index futures | Best | Raschke's own arena; deep books, stop clusters at obvious levels, reliable snap-backs |
| Index ETFs | Good | The same behaviour at daily-bar granularity, accessible without a futures account |
| Liquid large caps | Selective | Works when the down day was market-driven; fails when it was company news |
| Thin single names | Poor | The undercut is real selling more often than a flush, and the spread eats the tight stop |
Before taking the trade in any single name, ask what made the 80-20 day. If the answer is a headline about the company, the setup's premise — emotional selling with no news behind it — is absent, and the statistic was not measured on days like that.
How often the setup appears
Full-range 80-20 days are uncommon by construction — a day must commit essentially its whole range to one direction — and only some of them get the next-day undercut-and-recover. On a single index, qualifying trades arrive perhaps a handful of times a quarter, clustered in volatile stretches and absent in calm ones.
That is a feature for a trader running this alongside other systems, and a trap for one running it alone: weeks of nothing create pressure to loosen the thresholds or trade marginal recoveries, which is how a documented setup degrades into a habit of buying red days.
The two-session routine
- Evening: scan for 80-20 days. Two fractions per instrument — where the open and close sat in the range. A qualifying day goes on tomorrow's watch with its low marked.
- Next morning: watch the low. The expected script is early weakness through it. No break, no trade; a break that keeps falling, no trade either.
- On the recovery, act. Intraday traders enter as the level is reclaimed, per the book. Daily-bar traders confirm at the close and enter there.
- Then manage by the boxes. Stop beyond the flush low, out within two days, no exceptions on either.
The stated commitment — fifteen minutes after the close plus the morning of the trade — is honest, but the morning half is real attention: the trigger is a specific intraday sequence around one price. This is the least set-and-forget system of its size in the library, and anyone unable to watch the open should run only the close-confirmed daily version and accept its later entry.
Common questions
- Does this work in FX or crypto?
- The mechanics compute anywhere, but the setup leans on a defined session — an open and close that mean something — and on stop clusters at the prior day's low. Around-the-clock markets blur both: the 'day' is a convention and the ranges are less emotionally loaded. The published market list stops at index products and liquid large caps for that reason.
- Can I run it on weekly bars?
- An 80-20 week followed by an undercut of its low is a real pattern, but it is not this one — Moore's statistics and Taylor's one-to-two-day rhythm are about daily bars, and the time exit scales into a multi-week hold with no published support. Treat any such variant as untested.
