S&P500 Index's Best 2007 Total Return Performance: National Varco

I'm pleased to note that, as of today's market open, the best total return performer of 2007 in the S&P500, according to CNBC's Squawkbox program, is National Oil Varco.

Varco is in my current equity portfolio, with a return, since July, of over 34%. For the full year, it looks to have returned in excess of 100%.

This isn't the first time my equity portfolio has held the #1-performing S&P equity for a given year. The portfolio often holds at least one of the top ten performers, by total return, for the S&P in a calendar year.

It's a testament to how important a company's consistently superior performance is to its total return performance. And to how well our selection process works.

Still, Varco isn't our best-performing equity holding this half-year. It doesn't even have the heaviest weight among holdings in my portfolio. Apple is both our best performer of the second half of the year, with a total return of nearly 50%, and the heaviest weight level in the portfolio. MEM Electronic Materials has had a total return of roughly 43% this half-year, with a weighting similar to that of Varco.

It's reassuring to know that our equity portfolio selections and, by extension, our options selections, continue to feature top performers among the S&P500 membership for yet another year.
