Doom-gloom boom-zoom

One day, it is doom and it is all gloomy.

And then, without any real big change in the world economy, it becomes boom and the share prices mostly zoom up.

Is there a logic?  Definitely NO!  I still prefer to buy when people are dumping for the wrong reasons...  People pay equity traders big money to play around with their savings.  Wonder why any would complain about my fees when I am looking after their life.
