About 1.95M shares of VistaGen Therapeutics Inc are sold short. Short interest is roughly 5.57% of the float. At recent volume it would take about 1.00 days to cover. The borrow fee is near 1.08%. The squeeze score is 27.0 out of 100. No single number tells you whether a squeeze is coming, so it helps to read the whole picture below.
VistaGen Therapeutics Inc (NASDAQ: VTGN) had 1,952,907 shares sold short as of the August 14, 2026 settlement date, as reported by FINRA. That is 5.6% of the company's free float and a days-to-cover ratio of 1.00.
VistaGen Therapeutics Inc (NASDAQ: VTGN) is a healthcare company whose short-side positioning we track across four independent reporting systems: exchange short interest settled twice a month, FINRA off-exchange short volume published every trading day, SEC fails to deliver that arrive about two weeks in arrears, and securities-lending terms that move intraday. Each carries its own as-of date, so the sections below are read alongside one another rather than as a single snapshot.
The most recent settlement turned lower, breaking the run of increases before it. As of the August 14, 2026 settlement, 1,952,907 VTGN shares were reported short, equal to 5.6% of its free float.
The measured drivers are consistent and unremarkable, with short interest at 5.6% of float, days to cover at 1.00 and a borrow fee near 1.1%. Nothing in the short-side data currently stands out for VTGN.
Our squeeze score reads 27 out of 100, higher than 39% of the 4,939 US stocks we currently score. It shares that score with 180 other stocks, so this is a band rather than a precise placing.
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.
VTGN scores 27 out of 100. The biggest factor is short interest % float at 5.6% (low). Measured inputs: short interest % float at 5.6% (low); days to cover at 1.00 (low); borrow fee at 1.1% (low). Short-side pressure is middling by these measures.
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.
Ranked #2,845 of 4,939 US stocks we score for squeeze pressure — 180 others share the same score, so this rank is shared, not exact.
Reported short interest for VTGN 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.

VTGN shares that did not settle on time, reported by the SEC. Each figure is a running balance on a given date rather than a daily tally, and it is not added up across dates. Fails happen for many ordinary reasons and are not on their own a sign of anything improper.

The annualized rate a short seller pays to borrow VTGN. The latest reading is 1.08%. A high or rising fee means shares are getting harder and more expensive to short, which is one of the conditions that can feed a squeeze.
Indicative, bucketed availability from one broker (Interactive Brokers) — a single lender’s inventory for VTGN, not the whole-market shortable pool and not the short interest. Observed Aug 27, 3:17 PM ET.

A quick note on timing. The figures on this page come from different places and refresh on different clocks. Exchange short interest is reported twice a month, FINRA short volume lands every trading day, SEC fails to deliver arrive about two weeks late, and borrow numbers move throughout the day, so two figures here can carry different as of dates. We show measured figures only: where we have no data, the section says so rather than showing an estimate. Prices are delayed 15 minutes.
Not investment advice. This page is for education. Short interest, short volume, fails to deliver and borrow figures come from separate reporting systems with different as of dates and methods, and none of them on its own proves any wrongdoing or predicts where the price will go. Numbers can differ from other sites because of how float is measured, when each source reports, which venues are covered, and corporate actions like splits. Always do your own research and talk to a licensed financial advisor before you trade.
