Aug 9 (Reuters) - Wall Street was set to open slightly higher on Tuesday as oil prices steadied, a day after the S&P 500 index hit a record intraday high.
Oil edged further above $45 on estimates of a drop in U.S. inventories and speculation of producer action to freeze output.
On Monday, Wall Street closed down in one of its lowest volume trading day this year, after the S&P slipped 0.2 percent off its record high as healthcare stocks weighed.
"We expect a steady to higher opening as oil prices come back into the spotlight, said Peter Cardillo, chief market economist at First Standard Financial in New York.
"Today, it seems like whatever oil does, equities will follow."
Investors will continue to assess the rest of second-quarter earnings and economic data to justify valuations.

However, a forecast-beating payrolls report on Friday has helped bring back some of the risk-on mode in the markets. Safe havens gold and the Japanese yen were lower on Tuesday.
