People often ask me how I go about executing my short positions (SQ/FB most recently), especially when the company's fundamental story is solid.
I typically show them charts like this, where, as you can see, just by applying very basic technicals you can see that this stock (SQ) has a pattern of what can only be described as euphoric run-ups, followed by intense profit taking and shorts stepping in. I missed the first two short opportunities (wave 1/3) as I was patiently watching the price action. After seeing shares rally +1% per day in June and seeing the price action near the top begin to fade (wave 5), I entered a short (via puts) on 6/22 and am currently still in the trade.
I'm up ~145% as of 6/27/2018. Planning on closing this position when shares hit about $57-$55 (may close sooner depending on volume).
Long term, a company like SQ is solid, but I often say "watch out for euphoric run-ups, they end the same way every time". Just go check out a chart of AMBA or BTC.
The first idea published, just wanted to share some of my thoughts.
Let me know what you think :-)
Cheers!
