A deeply-drawn-down stock that reverses hard intraday can be short covering. This study isolates it in PLTR — >30% below the 200-day high and a −2/+2 reversal day — across all 20 occurrences since the 2020 IPO. But the plain average buries the signal that PLTR's construct has completely changed: the 2021–22 events were a speculative-bear dead-cat, while the modern, profitable, S&P-500 PLTR (2023+) turned every one of these into a winner. So the headline here is the current-construct weightingpre-2023 ×2, 2023–2025 ×6, 2026 ×9 — which flips the intermediate-horizon read from a fade to a hold.

Look down the +63d column: the deep-drawdown 2022 events (−50 to −74%) are a sea of red (dead-cats); the moderate-drawdown turns — 2023-03-13 (+99%) and 2025-04-07 (+84%) — are the launches. The live row updates from PLTR each build.

Plain median vs the regime-weighted view (pre-23 ×2, 23–25 ×6, 26 ×9). The weighting flips +42d/+63d from negative to positive — the fade was a 2021–22 bear artifact. The purple dashed line on the chart is the weighted median; gold is the live occurrence.
The honest read — reweighted to the current construct
1 · The near-term pop is regime-agnostic
Whether you weight or not, the entry works: +1.3% median at 5 sessions (55% green) with almost no adverse excursion. Short covering is short covering. The disagreement is what happens after three weeks.
2 · The weighting flips the intermediate horizon
Unweighted, +42d is -8.2% and +63d is -9.8% (a dead-cat). Weighted to the modern construct, +42d becomes +10.2% and +63d +1.7% median / +17% average, with the +21d win-rate at 79%. The fade was a bear-market artifact the weighting deliberately down-weights.
3 · Why the weighting is justified here
The 2021–22 events (weight ×2) were a pre-profit, pre-index, story-stock in an −80% bear — every bounce failed. The 2023–2025 events (weight ×6) are a profitable, S&P-500, AI-era PLTR, and all three worked: 2023-01-25 (−44% dd) +7% at 63d, 2023-03-13 (−31%) +99%, 2025-04-07 (−38%) +84%. Crucially they fired at moderate −30 to −44% drawdowns — exactly where PLTR sits today at -4%.
4 · The caveat the weighting can't erase
A weighting is a view, not new data. The up-weighted modern cohort is only n=3, and its +average is still carried by two moonshots. If PLTR is entering a genuine downtrend (not a shakeout), it reverts to 2022 dead-cat behavior — which is why the reversal-day low stays the hard stop. This expresses conviction that the construct rhymes with 2023+; it does not prove it.
Idea & trade — reassembled
Idea. Under the current-construct weighting, the −2/+2 reversal >30% below the 200-day high is not a rent-the-bounce dead-cat — it is a buyable turn in a name whose modern analogs (all at today's moderate drawdown depth) followed through hard. Hold it for the intermediate move, not just the pop.

Trade — hold the turn. Long PLTR off the reversal close.
Entry: the 3–5 day pop is the reliable get-in (+1.3% median, 55% green, tight risk) — but don't sell it at three weeks; the weighted edge keeps building (+21d +11% / 79%, +42d +10%).
Hold / target: the 21–63 session window (weighted +63d +2% median / +17% average) — trail rather than time-stop out.
Stop (unchanged): a close back below the reversal-day low = the turn failed, revert to the bear read.
Press on strength: a reclaim of the 200-day puts the +80–99% 2023/2025 tail in play — add there.
Size: moderate conviction — larger than a pure rent, but the up-weighted cohort is n=3, so it's a regime bet, sized accordingly.
Research, not investment advice. The weighting (pre-23 ×2, 23–25 ×6, 26 ×9) is a deliberate expression of the view that PLTR's current construct resembles the 2023+ regime; the underlying modern sample is small and tail-influenced. Verify against your own risk framework.
