"Just a day before Apple's new iPad becomes available in stores, the stock ticked up to $600.01 at Thursday's open before selling off. The new iPad, at a starting retail price of $499, costs less than one share of stock.Apple currently accounts for about 18.5 percent of the Nasdaq 100 stock index. Wow.
Apple Inc's rally has been stunning - the stock is up 47 percent for the year and nearly 10 percent for the month."
