Stocks are sharply higher so far on the week, with the Dow up 2.1 percent at 14,865 and the S&P 500 up 2.6 percent at 1593. Both indices are at record levels and are just a shot from the big round mile markers of Dow 15,000 and S&P 1600. The market saw liftoff in relatively quiet trading Thursday, with the Dow up 62 and the S&P up five. But the Nasdaq was up just slightly, held back by big declines in Microsoft and other techs, after fresh data from IDC showed the worst ever, 14 percent quarterly decline in PC shipments in the first quarter.

"It's kind of a rerun of yesterday," said Art Cashin, director of floor operations at UBS. He said the big banks should be the important drivers for stocks Friday morning.
J.P. Morgan is expected to earn $1.40 per share on revenues of $25.7 billion, and Wells Fargo is expected to report earnings of $0.89 per share on revenue of $21.6 billion.
Cashin said the market keeps rising with no sense of frenzy, which would be evident in a short-covering rally or if anxious investors were rushing in for fear of missing the market's gains.
"This kind of buying hints at buying that's not motivated by performance," said Cashin. "I think it's that 'I want to put my money where it's safe.'" Cashin said that means it's likely there are foreign buyers helping to drive U.S. stocks higher, and money may be leaving Europe because of Cyprus and Japan, because of the weakening currency.
Vassili Serebriakov, BNP currency strategist, said the markets are on alert, watching for fund flows from Japan.
