I'm researching short selling volume data reports from NYSE, NASDAQ and BATS (Sources: FINRA + BATS website). And my question is: Why are those numbers so high?
Is it really just a speculative short selling or a big piece is made from another transactions - like insider selling due Securities Act of 1933 prohibiting direct selling of securities obtained from issuer (so they are shown like shorts to regulators).
Compared to short interest (published 2 times per month) those numbers are insane.
I attach a chart with short volume as a percentage of total volume reported to FINRA and by BATS (this volume is significantly lower than total volume published by Bloomberg - what might be another reason) But distribution of short selling should be approximately same across trading venues right? (excl. darkpools of course)
