I'm not particularly bullish on INX-189, so such a bet makes no sense for me.
I'm not sure how a drug you like even less than lambda and yet selling for $2.5B is a slam dunk in-your-face (your statement was very in-your-face) indication that ZGEN was 'fair' at $1B. (Obviously INHX was an inflated deal - but greater than 2.5x?)
