Valid arguments Jorma. Doc‘s makes perfect sense, but i‘m simply not sure if it is possible to consider every source there possibly is. It would be just to easy to check the Fed‘s or Treasuries website, pull sone data and than make a forecast of comming price action in stocks, which would always be correct.
I‘m sure that those quick and large drops are engineered at will. We got them for example in 11, 14, 16 and this year. Every time all momentum players get kicked out. Basically every trader is a momentum player, cause finally every trading system is based on price monentum. So all those systems get effed up. The goal seems to be to reward only buy and holders. As if the powers that be would say:“This is our playground not yours!“ They simply don‘t wanna habe market timers on their turf.
