Tracked 15 pre-market gaps from the open to midday. Every up-gap held. 6 of 10 down-gaps faded.
Ranked this morning's pre-market movers at 9:45 by relative volume and options volume instead of by % gain, dumped the list into TradingView, and let it run.
Here's where all 15 sat pre-market.
The 9:45 board — 15 pre-market movers ranked by relative volume and options volume, not by gap size.

The asymmetry is the whole story:
| Ticker | Pre-mkt | Gap at open | Now (11:47) | Outcome |
|---|---|---|---|---|
| FRVO | +7.09% | +7.15% | +24.71% | extended hard |
| CRK | +9.63% | +9.63% | +9.01% | held |
| DUOL | +7.18% | +7.85% | +6.30% | held |
| NVS | +6.64% | +6.64% | +6.10% | held |
| MDT | +3.70% | +3.70% | +1.89% | held, halved |
| MSTR | −3.69% | −3.72% | −3.63% | held |
| NIO | −3.55% | −3.55% | −3.43% | held |
| TSLA | −1.92% | −1.93% | −2.59% | extended |
| AMD | −2.30% | −2.43% | −2.05% | held |
| MRVL | −3.09% | −3.12% | −0.99% | faded |
| INTC | −2.98% | −2.92% | −0.21% | faded to flat |
| IREN | −2.79% | −2.80% | −0.28% | faded to flat |
| XE | −3.60% | −3.60% | −0.43% | faded to flat |
| META | −2.45% | −2.54% | +1.37% | reversed green |
| SNDK | −2.60% | −2.56% | +2.45% | reversed green |
All five up-gaps still green. Of the ten down-gaps, four held and six either faded to flat or flipped green.
FRVO is the one to look at. Came in with the highest relative volume on the board at 5.41x, gapped +7%, now +24.7%. That's the whole argument for ranking on participation instead of gap size — it was 8th by percentage and first by volume.
INTC is the mirror image. Gapped −2.92% on 0.37x relative volume — below its own normal — and it's now −0.21%. A gap with nobody behind it.
Here's where my own thesis only half works.
Relative volume sorted the up-gaps cleanly — the two highest (FRVO 5.41x, CRK 2.83x) are the two best performers. It did nothing for the down-gaps. The six that faded had RVOLs of 1.15x, 0.46x, 0.37x, 0.35x, 0.41x, 0.45x. The four that held: 1.61x, 0.41x, 0.52x, 0.34x. No pattern at all. Low participation predicted a down-gap fading about as often as it didn't.
Caveats: one session, 15 names, and 11:47 isn't the close — some of these will look different at 4pm. And gap direction is confounded by whatever the broad tape did today; a market that rallies off the open flatters every down-gap fade.
Anyone tracked up-gap vs. down-gap hold rates over a real sample? One day tells me nothing, but the split was stark enough that I want to know if it holds.
