NEW YORK (AP) — Stocks are headed for a lower opening as investors become increasingly concerned about the debt crisis in Greece.

Thousands of people gathered in the streets of Athens on Wednesday to protest government cutbacks required to avoid a debt default. Credit ratings agency Moody's also said it may downgrade its ratings of France's three largest banks because of their exposure to Greek debt.

In the U.S., investors are awaiting reports on consumer prices and production at the nation's factories.

Ahead of the opening bell, Dow Jones industrial average futures are down 57 points, or 0.5 percent, at 11,961. Standard & Poor's 500 index futures are down 6, or 0.5 percent, at 1,278.

On Tuesday, the Dow jumped back above 12,000 and major indexes had their best day so far in June.
