I sell these intermediate bond portfolios for people that can't go to stocks.

Since we try and take a fairly buy-and-hold approach to our newsletter portfolios and don't sell at every whipsaw, we want to have a mix of stocks that will perform at both ends of the oscillation.

Optimization tells us precisely how to diversify the portfolio, whether I should have 12% in semiconductors or 4% in biotech, etc., and it literally tells me how to diversify not only the industry groups but the stocks.

I grade my stocks. I'm what they call a quant, one of the geeks of the stock market.

If you are a short-term trader, you have the right to come and go from our funds.

Often, there are 30 or 40 stocks in the portfolio, and the (trading) turnover is fairly rapid.
