From my perspective, I most care about having the best setups possible - given whatever market environment we are in. Obviously we are all in "continuously learning mode" - especially these last few months. As an example, I realized after reading a post by @Kim that I have put too much negative bias into some of my trading decisions - whether getting in or getting out of various trades. Because I believe the market has been acting irrationally as of late, I have not taken part in anywhere enough of the uptrend as I should have. This is a bad practice -- one has to trade the market we are given and not try to MAKE it what we believe it should be. Now, that is easily said and having a bias is a natural human trait - and most of us have learned to trust in our hunches, wisdom, learned experiences, etc . . .but sometime they fail us.
Now back to the subject of performance and portfolio sizes. I think the goal of a 10K portfolio is great, but I also wonder how many of us "goose" up the size of our trades to work better in larger portfolios - I do this all the time.
What I do think is important is that if there are some really good setups that are a bit on the expensive side - would still like to ponder them. Maybe they go into the "unofficial" bucket . . . or maybe a "Big Kahuna" bucket that is kept separate from the 10K portfolio bucket. I'm not trying to add more work to anybody's plate - more along the line if you see some good viable setups - maybe discuss them and let the SO members know that some are not being taken due to size/cost . . . but they're still valid and here is where you go to see them.
Okay, enough out of me . . . seems my "negative bias" is just starting to match the market a bit more . . . I feel like some more "reality" is starting to creep into the market. We shall see!
