How PLUG got to 31 / 100
The PLUG squeeze score is a weighted sum of five normalized components, short interest as a percentage of float, IBKR borrow fee, float utilization, days to cover, and trailing 5-day price momentum. Each component is z-scored against a universe of roughly 500 active US equities, then combined with the weights shown below.

Frequently asked questions about PLUG squeeze risk
What does a Short Squeeze Score of 31 / 100 mean for PLUG?
A score of 31/100 for PLUG 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 PLUG squeeze data?
PLUG'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 May 15, 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 PLUG on the FINRA threshold list?
As of the most recent FINRA file, PLUG is not on the threshold list. The list is published end-of-day and a ticker can move on or off based on cumulative settlement failures over rolling five-day windows. See stocks currently on the threshold list.
