06/30/2012 two additional notes on position sizes

Just two short points:
A cash only account trying to follow the large model would begin with ten equal sized positions, and would NOT re-invest dividends.  The reason for this is that over time each stock will have different amounts of gains, and the cash from the dividends would tend to limit the imbalances in the position sizes.

A margin account trying to follow the large model would begin with ten equal sized positions, and would not re-invest dividends either.  But the amount invested for each new stock would always be the same: 10% of the highest value the account has achieved.  The total drawdowns would be the same, but the recovery would be faster and of greater magnitude.
