Apparently, I am much more of a gambler than you are. I don't gamble just to gamble, I prefer to do it when I have an edge. For example, when I go to Las Vegas to gamble, I count cards and play blackjack. You can still lose counting cards, but you shift the odds in your favor and pays over the long run. I consider Biotech stocks in that same way, and I really like my chances with ENTA. FWIW, I nibbled and bought a little bit more ENTA this morning at just above $40.
My IRAs from work are in various mutual funds, much of it low load in TIAA-CREF. I also have a separate money in my personal account where I focus on Biotech with some of that in dividend producing stocks you live like ABBV and BMY. I did diverge and add some APPL and NFLX in July and have a small loss for APPL and a nice gain from NFLX.
