The share price did not fall 40%+ due to small time investors panicking. It was institutions that sold and they sold very hard, and the small time investors followed suit.
The actual end point for 214 is to be determined in the future. The numbers they used were quite tiny to begin with in regards to number of patience. They will have plenty of time to give each patient time to respond in Phase 3, and I am sure there will be updates on the numbers when the data matures again on the additional patients.
But no one is missing the fact that this drug does better as time drags on. That is being taken into account. What they are looking at is the competitive environment that 214 has to sell into if approved. They want front line (at least in the future, if not outright at the beginning). Not second to third line treatment. The difference in value is stark, in the billions and billions of dollars. Thus the forward looking valuation, off the back of napkins for many, had to go way down.
Did they overshoot? Probably. On the New Paradigm board I wrote about the almost universal pattern fo successful biotechs. KITE was an exception to the rule by JUNO followed it. The stage we are in now is the Martha Stewart stage where usually someone goes to jail (that won’t happen here, but it feels like someone should). This has happened to practically every successful biotech I ever invested in. And fortunately I usually did not invest in them until the company reached this stage of clinical development (although I got stuck in EXEL just before this).
The next stage, after panic, illegal insider selling, arrests etc. (Martha Stewart stage - and again the criminal element won’t happen here but I use if for effect) is that o average, say 18 months, the stock will make a remarkable comeback and may even be multiples higher than from where it fell.
However, given how high NKTR was before it fell, I do not know if the multiples higher will hold here, but the same general thing will happen in this stage.
This is the time that tests your fortitude, like no other in investing. Easy for me to say because I do not own any (my 2 day trial period convinced me I do not need biotechs in my life at this point in my life, so got rid of it and bought more NVDA and ANET at the time), but it is also the time to take a very deep dive into the company, and for those who have been waiting for the Martha Stewart stage to hit, see if they really do want to dive in big time and then go in hybernation as the nearly inevitable recovery stage slowly rolls out.
