Fed and the pattern
It works until it fails. The reason I am less confident is that the macro picture is signifantly worse than it has been at prior fed sell off times. If the last few days were actually the start of the big down draft that everyone is expecting AFTER the next bounce, we will have a string of 6 to 9 days down before a green close.
I went out for dinner right after the fed announcement and got back 15 minutes before the market close (I'm in UK) and thought of reducing my short positions for the expected bounce but I could not find any that I honestly felt it was worth bothering. If we bounce big, I sell it. If we don't bounce, I need to do nothing.
What the fed report immediate bounce did, it gave me some December, November and October puts quite cheap in ETFs that tend to have large spreads and poor liquidity, BKX in particular. All of them closed more 10% or more in profit. But it is nothing once the indices they follow actually fall apart.
