During COVID-19, I have predicted things several days in advance, but that's about it - never the whole picture early on.
I predicted China would hit 10,000 cases several days before that happened. The market reacted, but I hadn't thought to put money behind it.
The Feb 28 stock market drop was pure panic, and felt like a local low point, so I pushed in +2%. That was correct for the following week - it was a local low point. Then COVID-19 hit the U.S., and a new panic began.
On Monday, Mar 9, I placed limit orders to sell some equities at the market open (see "An experiment" thread). My theory is that the U.S. will hit 10,000 cases and cause further panic, so I'm waiting for that to happen. Note that isn't calling the lowest point - it's just predicting a panic, and being in bonds until it occurs.
So... predicting several days in advance, multiple times? But no, I didn't predict a worldwide pandemic in Early February.
