Stocks were down for the day but not for the month. In May, the S&P added more than 1% and the Nasdaq was up nearly 3%. Altera (ALTR) was among the best performers on the Nasdaq after reports said Intel (INTC) was nearing a deal to buy the chipmaker. Oil closed the month above $60 a barrel, its highest level in a week. A sad day for American Express (AXP) as President Ed Gilligan passed away after 35 years at the company. Gilligan died after becoming suddenly ill on flight to New York. Humana (HUM) was an interesting mover, spiking 20% in the afternoon session on reports the company is considering putting itself up for sale.
