RE " institutions (at the margin) won't invest with red flags"
EXACTLY! and PPHM is and has been a little company with a horrible history, horrible dilution, and management that the street doesn't trust.
Yeah, the science is "interesting" , but that doesn't mean they ignore red flags and invest.
REMOVE the red flags and the stock will go up.
PPHM has never been willing to do this, AND their shareholders have paid the price.
Now they expect shareholders to grant options year after year, AND vote themselves into another massive dilution? CRAZY.
You want shareholders to do something for you? do something for them.
This isn't charity, it's supposed to be an investment.
