About 4.41M shares of Nkarta Inc are sold short, or roughly 9.26% of the float. At recent volume that works out to about 5.10 days to cover, with a borrow fee near 30.27% and a squeeze score of 38.0 out of 100. No single number tells you whether a squeeze is coming, so it helps to read the whole picture below.
This page gathers everything we track on the short side of Nkarta Inc (NKTX) in one place, ordered by how quickly each number changes. The fastest moving figures, like the borrow fee, sit near the top. Daily figures such as short volume and fails to deliver come next. The slowest data, the official short interest that exchanges publish twice a month, sits at the bottom. Reading it top to bottom gives you a feel for what is happening right now versus what has built up over time.
Where the numbers come from. Short interest and short volume are reported by the exchanges and FINRA rather than any single broker, so they reflect trading across the whole market. Float and shares outstanding come from a separate data provider on their own schedule, which is why the percentages can shift even when the raw short interest has not changed.
Is short interest reliable? It is not something a company reports about itself. Brokerages are required to report their open short positions to FINRA twice a month, once around the middle of the month and once at the end, so the figure is a real settlement number rather than an estimate.
What about dark pool trades? They are included. A trade executed in a dark pool still prints to the tape and settles like any other trade, so any short position it creates is counted at the next settlement date no matter where the shares changed hands.
NKTX scores 38 out of 100. The biggest factor is days to cover at 5.10 (elevated); days to cover of 5.10 is elevated and a borrow fee near 30.3% is elevated. Short-side pressure is middling and nothing here points to an imminent squeeze.
A relative reading versus other stocks, not a prediction. It weighs short interest, float, days to cover and the cost to borrow into one 0–100 number where 50 is the middle of the pack.
Reported short interest for NKTX at each date, shown with days to cover and short interest as a percent of float. Short interest updates twice a month; the percentages are recomputed as float changes.
