NEW YORK (CNNMoney) -- U.S. stocks were set to edge higher Tuesday, following a report that showed home prices rose for the first time in eight months in April.

Dow Jones industrial average (INDU), S&P 500 (SPX) and Nasdaq (COMP) futures were more than 0.3% higher ahead of the opening bell. Futures measure current index values against perceived future performance.

Before the housing report, futures were pointing to a lower open, as Greek Prime Minister George Papandreou continued to call for deep spending cuts and tax increases.

Lawmakers began debating an austerity package Monday that is needed to secure financial aid for the struggling country. Discussions continued Tuesday, and Greece's parliament will vote Wednesday on a five-year budget plan.

Greek workers also began a two-day general strike, which is expected to shut down much of the country's transportation systems.

"Uncertainty persists ahead of the Greek budget vote," BNP Paribas said in a research note. The austerity measures are largely expected to pass on Wednesday, but markets will likely remain "highly skittish" until then.

Longer term, while jitters about Greece's debt crisis and the health of the eurozone will still hang over the market, they could be overshadowed temporarily by optimism about the upcoming earnings season.

Stocks started off the week with solid gains, as strength in the technology sector boosted all three major indexes.
