Nothing happens to the share price. If STSI is below $2 at closing, then those folks short the puts will get assigned shares at $2 each. Those people long the puts, if not having cashed them out for money before 4pm tomorrow, will then exercise the puts and dump their STSI shares to those short the puts for $2 each.
Now price is driven from 2 put option at 2 and 2.5;put 2 is at about 0,1 Put 2.5 is at about 0,6.
open interest put2 is about 11000 and open interest put 2.5 is about 8000. Both control 2 million share. This justifie price at 1,88-1,89;
Seems that shorters that have buy put at these price was not able to go ahead.
