The unofficial start of the summer is here, setting up a winning trade in certain slices of the U.S. stock market, if history is any guide.

As investors spent their Memorial Day holiday weekend relaxing on the beach, CNBC Pro ran the numbers to find the stocks that tend to outperform during the summer months.

Using data from Kensho, a tool designed to quantify historical events, we conducted a study of the past 20 years to spot any trends from Memorial Day to Labor Day.

Among the major indexes, the Nasdaq 100 was the top performer, posting a gain 60 percent of the time, up on average 3.8 percent, according to Kensho.

Within the S&P, the sectors with the biggest odds to rise are health care and tech, up on average 2 percent and 3 percent, respectively.

But CNBC Pro focused on the summer's favorite industry: leisure.
