A Reuters report reveals that Apple Computer will join the Standard and Poor (S&P) list of companies whose stocks are listed in the S&P 100 index. This is expected to result in an even better stock performance for the Cupertino-based company.

The S&P index is the most watched index of its kind in relation to American stock trading floors. The inclusion of Apple marks its entry as a marquee blue-chip company which commands a stable and profitable holding.

Along with Apple, Oregon-based engine maker Precision Castparts was included in the list. The index is dominated by American enterprises though European firms have exhibited a steady rise in the last few years.
