So FINRA can’t give you an accurate accounting. Activity includes intra-day shorting, but that doesn’t mean short positions increased EOD. They can net/net keep them neutral, but use intra-day shorting to influence SP. It would probably be more accurate to state x% of today’s activity was short generated. What one should look for has there been any Fail-To-Delivers in the past year. This tells you at one time all the shares available to short have been fully lent out, a very rare occurrence to have an FTD, and should be concerning. I was getting emails from Charles Schwab to lend my shares out, someone wanted to short them, I’d get paid interest, said no. Then IPIX issued more shares, so I assume their are plenty of shares now for shorting. I wouldn’t short IPIX, shorts are misguided on this on IMO.
