I shorted ABNB @213 based on fundamentals. The company makes no money, trades with crazy multiples, and has negative cash flow. Given that the market was getting shaky this is exactly the fragility I was looking for in my short. Just by pure luck, it turned out to the top (so far). Looking at the chart now, I also get some inspiration from the technical side. There is a possible H&S with a 140 or so target.
