$GLSI This news is two weeks old so don’t blast me for it but I skimmed and didn’t notice the comment where the company expects they could earn an annual revenue of 8-10 billion if GLSI-100 were approved for non HLA patients as well. That’s a possible market cap exceeding 40 billion….. share prices would be in the thousands….. obviously this is the best possible outcome but holy shi+!! I just canceled my limit orders and I’m letting my 2,443 shares ride or die, that’s generational wealth!

$GLSI Congrats to longs! You absolutely deserve a holiday gift like today's rally. Don't get complacent though. Price action from halved to doubled is not even stretch for the hedge funds who'are behind this. And don't forget the sp has been higher twice in the past 3 years. I won't be surpriced the price gets above $20 or it drops to $12. What matters is P3 trials are making steady progress and Snehal's execution so far is near perfect. ATM strategy works well and it seems the chance for a one time dilution is minimal. For now, the financial concern is in the rear view mirror, we can focus more on the trial side of the news. The most encouraging update is that we now have strong patient driven interest, which will accelerate the trial in full speed. With all the progress so far, GLSI is probably worth $20-30. It will be way more if 80% reduction is achieved at the end point.
