INXB / Inhibrx Biosciences, Inc. Stock - Short Interest, Short Squeeze, Borrow Rates

Where does Fintel get its data? We source our short interest data from a variety of providers. The Short Interest figures we provide are sourced directly from the stock exchanges (NASDAQ, NYSE, NYSE American, NYSE Arca, CBOE, and IEX) and FINRA. This is the official data and covers a broad spectrum of the market. We do not source short interest from a single broker. For Canadian, Australian, and Hong Kong markets, the short interest is published by the regulatory agencies of those countries. We get this data directly from those agencies on a daily or twice-weekly basis. The float and shares outstanding we use are sourced from Capital IQ, which is one of the top firms that provide this data.

Is short interest self-reported, and therefore unreliable? Short interest is not self-reported. FINRA and U.S. exchange rules require that brokerage firms report short interest data to FINRA on a per-security basis for all customer and proprietary firm accounts twice a month, around the middle of the month and again at the end of each month. See Short Interest — What It Is, What It Is Not. for more information.

Are dark pool trades counted in short interest figures? Yes, they are. The primary difference between a dark pool and a lit exchange is that pre-trade information such as bid/ask are not available. However, once a trade is made, dark pool trades are published on the tape and tracked like every other trade. When it is time to report, any open short positions are reported, no matter what type of trading venue those shares were acquired on.
