MA: Parabolic price action & valuations = Massive Short

When I see parabolic price action like Mastercard's weekly chart, I start thinking on how to structure a short because we all know parabolic price action always always ends in tears. It does help that MA is trading at....3.5x of its average 13-years P/B and has a...-0.25% real earnings yield (adjusted for US 10 T-bond). With MA implied vol trading at an elevated 34 and a nice skew, one can structure a July -5/-15 put spread for c.1.6% with a max c.4x payout if MA hits the min price target of $144 (being the weekly 38.2% retracement). I am most probably too early on this call with my short term tactical view being positive as we head into earnings season (MA reports 2 May'18) but...it is either you get the high vol or a better entry price. Either way, I would like to get some optionality into the books.
