Re: "I can't follow Zeev. Is there any pattern to his line of thought?"
I think so. While I wouldn't presume to imagine I know how he thinks, I have been able to catch a few glimpses. They go something like this:
1) Concentrate on facts.
2) Squeeze out ego.
3) Make a projection.
4) Act. (Note: Inaction is a valid act.)
5) Go to (1)
The foregoing is not a single process; it is multiple processes. I'm not sure what they all are, but there is one for each stock traded, there is one for where the market is headed, and there is one for our economic circumstances. There are constraining influences, including a commitment to work the long side only, when trading stocks.
Item 3 is the only step that requires an opinion, and that, by the influence of item 2, is as rational as it can made.
Note that the process permits constant adjustment of the projections. Thus, there is no inconsistency when a projection is changed. It is an adjustment (and a new basis for action), predicated on newly acquired facts, unsullied by egocentric fears that earlier projections might have been wrong.
Lest anyone think I know what I'm talking about, this is an opinion formed from reading Zeev's posts. It has no grounding in knowledge or fact, beyond that.
