BW Analyst read

HYLN (AMEX: HYLN) had 17,826,174 shares sold short as of the August 14, 2026 settlement date, as reported by FINRA. That is 14.2% of the company's free float and a days-to-cover ratio of 4.26.

HYLN (AMEX: HYLN) is tracked here 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.

FINRA has reported 5 consecutive increases in HYLN settled short interest, a cumulative 61.4% increase across those settlements. As of the August 14, 2026 settlement, 17,826,174 HYLN shares were reported short, equal to 14.2% of its free float.

The measured drivers disagree: days to cover at 4.26 sits toward the stretched end, while short interest at 14.2% of float and a borrow fee near 0.4% do not. A mixed reading like this says more than any single figure taken alone.

Reported short interest for HYLN 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.

How many HYLN shares were sold short off exchange each day, summed across the reporting venues we track. It includes market maker hedging and other routine activity, so a high reading is normal and is not the same as outstanding short interest.

The same off-exchange volume above, split across the FINRA trade reporting facilities that publish it. These are reporting venues, not exchanges — FINRA publishes off-exchange activity only, so this is not a full market count and the rows are not summed here. The consolidated total in the section above is the authoritative figure.

HYLN 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 HYLN. The latest reading is 0.42%. 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.
