Anyone with stocks can just go away and ignore the noise, but anyone with any options really needs to think out a strategy and to be fair I don't have a good one yet
My options strategy was to close my single open option position, which was firmly in the red. This might be a poor decision, but that the moment I think the risk/reward curve looks unhealthy.
As many others have pointed out, we have already had a solid correction in high-multiple stocks. This could just be a temporary correction.
But on the other hand, a lot of high-multiple (or even earnings-negative) stocks have a day of reckoning coming. I am thinking of the social media stocks like Facebook, Twitter, LinkedIn and a lot of biotech firms which are valued on revenue multiples rather than other metrics. How anyone can detatch earnings from their analysis to this degree is a mystery to me. Honestly, I do computer software for a living and I think Facebook's $150 billion valuation is ludicrous. So does Facebook's management, judging from how they're treating their stock like monopoly money in their acquisition strategy. These companies almost have nowhere to go with regards to growing their earnings - at least not the 100x earnings growth implied by their current valuations. Facebook
might, seeing as some of their latest acquisitions have serious strategic merit (Whatsapp, Oculus VR). But regardless, in a broader market downturn (which we already have to some extent), these stocks will get slaughtered and brought down to a more suitable risk/reward level. Bubble is such an inflationary term, but there is irrational investor behavior in this sector. Maybe fueled by low interest rates and the fantastic boom/success of hundreds of early-stage startups in the US.
The problem is, in a downturn like this, all momentum stocks will get identical treatment from fund managers and retail investors. If this scenario occurs, we could easily have Tesla back in the double digits. This would of course be a magnificent buying opportunity provided that car buyers don't stop buying cars in the meantime, but an options portfolio would get hammered regardless of Tesla's execution. Hell, I didn't think Tesla would hit $150 before 2017, so it would surprise me very little to see $150 again before the year is over. Seeing $320 would scare me, I think.
Of course I am also writing this now that we're down 25% already, and the NASDAQ is down almost 10%. The correction could be behind us. But there is plenty of downwards potential here still, even in the absence of negative news. Stock market irrationality goes both ways. (If $100 sounds like a fairy tale, imagine how things feel if the NASDAQ falls 30% from its peak - a completely precedented stock market crash even during the current decade. Note I'm talking risk management here, not prediction).
