NEW YORK — An unexpected rise in jobless claims is causing investors to sell again.

A day after the Federal Reserve expressed confidence in the economy, the government said new unemployment claims rose last week. The market expected a decline, and stock futures fell.

Investors have been nervous about how long it will take the economy to turn around.

Early today, Dow futures are down 45, or 0.6 percent, at 8,211. Standard & Poor's 500 index futures are down 5, or 0.6 percent, at 893. Nasdaq 100 index futures are down 6.50, or 0.5 percent, at 1,440.75.

Meanwhile, the government reports a slightly improved reading on gross domestic product. First-quarter GDP shrank 5.5 percent, less than the previous estimate of 5.7 percent.
