Dividends are finally getting some respect. The S&P 500 now counts 402 of its members as regular dividend payers. That marks the highest number of companies tossing cash at their shareholders since December 1999. New companies on the list include longtime holdouts Dell and Gamestop, who both waded into the dividend pool for the first time this summer. Apple (NASDAQ: AAPL) cannonballs onto the list this week, as its first dividend payment — of $2.5 billion – hits millions of shareholders’ accounts on Thursday. When that happens one of the most widely held stocks in the market will become one of the most widely held dividend stocks in the market.
