(Reuters) - U.S. stock index futures edged higher on Wednesday as investors strengthened bets on an earlier start to rate cuts by the Federal Reserve this year than previously expected, after a string of economic data pointed to slowing economic growth.

Wall Street ended Tuesday's session slightly higher, paring some losses, with rate-sensitive real estate stocks leading sector gains.

That came on the heels of initial losses after data showed U.S. job openings in April fell to their lowest in more than three years, the latest economic report to suggest growth in the world's largest economy is cooling. This allows the Federal Reserve more room to cut interest rates.

Markets are now pricing in about 44 basis points of easing this year. Additionally, expectations for a September rate reduction now stand around 65%, versus below 50% last week, according to the CME's FedWatch tool.

"The JOLTS report follows a string of soft economic data releases and suggests a gradual cooling in the US economy... market participants are likely to welcome a cooling economy and the prospect of monetary easing, given the overwhelmingly bullish outlook among investors," analysts at BCA Research said in a note.

Signs of steady inflation and resilient economic growth had forced markets to dial back hopes for both the timing and pace of interest-rate cuts at the start of the year, when many expected policy easing to begin as early as March.
