I know for a fact that there is no one indicator that can predict the market top. Give me one such indicator and I will refute it. Every peak is different and you have to look at the totality of all the evidence put together.
You brought up lots of good points. Lots of those calls were right on the money though and although long term they didn't work out, but they made money for the poster short term because the market did drop after those calls. But a time frame should be posted. That being said, I have just sold SPX vertical 3100/3105 calls 38 days out. Why? 1. Time works for me, instead of against me. 2. My possible loss is predetermined. 3. If the market goes sideways, I can still profit. 4. Even if I am wrong, if I can time the market intraday, I can get out of it with no loss or even gain by closing the wings separately. It is a kind of a binary position, I either make X or lose X (and everything in between).
I was always having giggles seeing all those top calls, but one of them is bound to be right. And i think OP could be right. Timing seems to be right this time. Markets seem kinda toast.
I am surprised by the foolishness of "professionals" "investing" in WeWork. It will be the poster child of this upcoming crash, even if I am a month or two off. When you are down on your investment but have $3 billion to spend, do you throw it to give WeWork CEO severance? Or do you use it to buy out completely the largest competitor Regus with more customers (more everything) than WeWork? I think 5th grade kids playing basic checkers can make a better decision. Of course, an even better decision might be to fold completely, but it seems that even when trying to double down, they ask themselves what is the worst move that I can make and do just that.
