S&P Global's Sam Stovall told investors Monday of a "free lunch" investing strategy that beat the market's return with lower risk.

The strategist cited how technology was the top performing sector in the market with a 9.8 percent annual return versus the S&P 500's 7.0 percent since 1990. However, technology stocks had a standard deviation of returns 80 percent greater than the market.
