ENPH Short Squeeze Score: 44 / 100
ENPH ranked on Tapeboard's 0-100 short squeeze leaderboard · components disclosed below · methodology fully published
This score isn't static, short interest re-settles every two weeks and ENPH's borrow fee can spike intraday. Tapeboard re-scores ENPH every day, ranks it against the full live squeeze board, and pairs it with a real-time scanner and watchlist, so you catch the setup changing, not a snapshot. Free, no card.
How ENPH got to 44 / 100
Since setup v5 (2026-09-28), a stock is ranked only if its short interest is at least 15% of float. Since setup v6 (2026-10-07), ranked names are scored 0-100 on 20-day volatility with the single largest daily move excluded (60%), 5-day float rotation (20%) and last-session relative volume (20%), each as a percentile among the gated names. A higher score means higher historical odds of a large move in either direction; it is not a directional call. The inputs below (short interest, borrow fee, float utilization, days to cover, momentum, short-volume ratio, fee change) are shown for context at zero weight.
| INPUT (CONTEXT, WEIGHT 0) | VALUE |
|---|---|
| SI %Float | 21.9% @ Sep 30, 2026 |
| Borrow Fee | 0.3% |
| Float Utilization | 21.9% |
| Days to Cover | 5.5 |

How the score is calculated
Tapeboard's short squeeze score (setup v6) gates on short interest of at least 15% of float (FINRA settlement, point-in-time and split-safe), then ranks by 60% 20-day volatility percentile (single largest daily move excluded) + 20% 5-day float-rotation percentile + 20% last-session relative-volume percentile. Out of sample, the top 10 moved +20% within five sessions about 17% of the time and fell 20% about 12% of the time, against 4.5% and 2.3% for all stocks. Sources: FINRA consolidated short-interest files for short interest, daily bars for volatility and rotation, broker-dealer stock-loan data for borrow fees (context), and FINRA CNMS daily short sale volume files for the heavy-short-volume flag (context; not the Reg SHO threshold list). The full methodology, including the calibrated odds table and known limitations, is published at /methodology/short-squeeze-score.

Frequently asked questions about ENPH squeeze risk
What does a Short Squeeze Score of 44 / 100 mean for ENPH?
A score of 44/100 puts ENPH in the middle of the setup board: heavily shorted, with volatility and float turnover around the middle of the gated set. Historically, mid-board names (ranks 26-50) reached +20% within five sessions about 10% of the time and fell 20% about 4% of the time.
How fresh is the ENPH squeeze data?
ENPH's score recomputes once daily after the US market close (typically by 9 PM ET). Volatility and float rotation come from daily price bars; borrow fee and the other context fields refresh daily. Short interest is settled as of Sep 30, 2026 and is held between readings, because FINRA publishes short interest on a settlement schedule, not daily. That is why the SI %Float row above is stamped with its own as-of date. Real-time short interest does not exist publicly in US markets.
Is ENPH on the FINRA threshold list?
Yes, ENPH appears on the current FINRA Threshold Securities List, meaning aggregate failures-to-deliver have exceeded the regulatory threshold for at least five consecutive settlement days. Threshold inclusion is a backward-looking confirmation of covering pressure. See all stocks on the threshold list today.
