either way imo, pps will not fluctuate too much even after R/S as it has not fluctuated much last few days, due to people holding for FDA clearance.
I see that scenario of holding for news continuing even post split
Granted it may bounce around a bit though.
That's just my personal take, and while I was prepared to sell all before split if no FDA news, I will now hold. Part of that is because of the recent expansion in their facility and length of the lease.
And this is not a typical penny stock, it's Nasdaq.
