The short interest numbers were as of 3/13/20 (when I had called about the numbers I was told that they update once per month).
On 3/13/20 SOLI PPS was around $.30. Since then we have seen the volume go crazy and the PPS go all the way to $.88 (yesterday). I do wonder what the short interest is now? Also, we know that when the name and symbol is changed any shorts need to cover. Could be interesting.
