Seriously considering trading 6-8 smaller ($20K or even less) positions, instead of 2-3 large ($35-40K) ones. Unfortunately, there is no way I can do this and get to work at reasonable time.
I've often wondered if trading a "mini-portfolio" during the day with a maxLoss setting and profit target would be feasible.
The different between 2-3 and 6-8 in terms of the volatility of the portfolio is big. One would think that 8 positions would have a significant smoothing effect. Of course, it depends on the correlations of the assets but here is a picture that makes a good illustration of diversification and # of different assets.
