Wise up people. I saw some good perspective in previous threads: A) The run is over (at least the run based on PCSK9) REGN is now in the "buy on rumor, sell on fact" phase. Anyone ever heard of that? It's a very common expression. REGN is selling at a whopping 160 times earnings. They have to KILL IT with PCSK9 for this to hold up. The whole category is going to disappoint in the short term. Uptake will be very slow. This stock will see <400 in the next year. If the whole market corrects this summer, a stock this overvalued will lead the pack. Been investing in Biotechs back to early DNA (Genentech's former trading symbol, AMGN when it was a darling of Wall street, Biogen, Medimmune, Sepracor, Idec, ALXN, you name it, I might have owned it. Go back to 1993 and look at AMGN stock. Company was growing 25% QUARTER OVER QUARTER and that year the stock went from 90 something (after several splits) to 30 by the summer. Why? It was trading at 120X earning when the market corrected. If you didn't get into REGN as an employee early you will not see the "biotech millionaire" label on your REGN stock portfolio. Still a very good company though. Their science platform is exceptional and worth watching for a good buy in point when the correction does happen. Thanks for letting me blather. I'll be waiting patiently for insulting replies.
