i spent my academic career as a physicist; and my working career as a business analyst for commercial banks - particularly in the field of credit and lending. i've spent a considerable time trying to decide if i as an investor or trader; and even more time trying to impose discipline in my stock related activities. i have a membership in AAII and use folioFN. i have tried to use several portfolio analysis tools, to evaluate risk and return, the one from Quantext more than once. and, i am still in search of an excel based trading log and a portfolio tracking tool to give me a better sense of feedback on my good and bad decisions. aside from that, retirement is not too far down the road, so i'd better get this right pretty soon.
