How SPWR got to 24 / 100
The SPWR squeeze score is a weighted sum of seven normalized components, short interest as a percentage of float, IBKR borrow fee, float utilization, FINRA CNMS daily short-volume ratio, days to cover, trailing 5-day price momentum, and the borrow fee's 5-day change. Each component is z-scored against a universe of roughly 500 active US equities, then combined with the weights shown below.
| COMPONENT | WEIGHT | RAW | CONTRIBUTION |
|---|---|---|---|
| SI %Float | 36% | 9.5% @ Aug 14, 2026 | - |
| Borrow Fee | 18% | 6.8% | -0.03 |
| Float Utilization | 0% | 9.5% | 0.00 |
| Days to Cover | 9% | 1.8 | -0.10 |

Frequently asked questions about SPWR squeeze risk
What does a Short Squeeze Score of 24 / 100 mean for SPWR?
A score of 24/100 for SPWR indicates the structural squeeze conditions are weak today. That can change fast, short interest reports settle bi-monthly, and borrow fees can spike intraday on adverse news.
How fresh is the SPWR squeeze data?
SPWR's score recomputes once daily after the US market close (typically by 9 PM ET). Borrow fee, float utilization, and momentum refresh daily and are live. Short interest is settled as of Aug 14, 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 SPWR on the FINRA threshold list?
Yes, SPWR 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.
