Mr. Mike, have you considered using Vanguard, Schwab, or Fidelity to invest this money for you? My 401k is with Vanguard and they're managing my account to my specs (too aggressive for my age) I am EXTREMELY happy with the results. Most important, I can sleep at night when I shoot myself in the foot with with my free cash. Back in the day when I first started buying and selling my own picks, I was terrified that I'd screw up and lose everything I'd saved. My deal with myself was, for every 1k I put into my personal let's-see-what-happens brokerage account, I'd put an equal amount into Fidelity or Vanguard. That way, when I lost everything trying to trade Pink Sheets crap, I still had gains because of Vanguard and Fidelity. I used margin about three times. Twice it worked in my favor, then one time I had to dash to the bank in the middle of the day in order to cover the call that came unexpectedly. Now, I have margin but haven't used it in years. It's there just in case. Just my 2 cents.
