Well those are good TGTX questions. I never have understood the insanity of diluting at a discount, but it is what it is. I always felt like a company that is making research progress, should ask for more $$s per share as the IP is perfected, but I don't run Wallstreet, LOL.
I do Research, biochemical engineering.
I have seen reports in 8-Ks where the price of dilution was set ahead of time at a 30 day average of the market price. Then they probably sell put options to fools, buy the float up and jack it up to lala Blue sky land, and collect on the puts, then sell call options, and then once the new shares show up, or are about to be PR'd or 8-K'd the selling begins, and they cash in again on the sold call options (puts) once they have dumped the float back on retail.
