In this article, we will discuss: 10 Most Profitable Small Cap Stocks to Buy.
According to Jamie McGeever’s Reuters Open Interest column on June 2, 2026, small-cap shares led the AI-driven boom, with the Russell 2000 index jumping 17% this year, surpassing the S&P 500’s 10% rise. As per the column, smaller firms benefited from the projected $800 billion AI capital expenditure cycle, with gains concentrated in technology and energy. Keith Lerner, chief investment officer at Truist Advisory Services, commented that “this underscores how strong and widespread that demand has been,” pointing out rising participation across small-cap semiconductor and equipment-linked firms.
McGeever reported that small-cap tech equities have risen 45% year to date, compared to 25% for large-cap tech, while small-cap energy is up 34%, compared to 27% for its larger peers. He also pointed out that small-cap energy has grown by 13% since February 27, compared to 2% for large-cap energy, and small-cap technology has increased by 70% since March 30, compared to 45% for large-cap technology. Bank of America poll data showed 54% of fund managers expect large caps to outperform small caps, the highest since June 2022, as investors weigh the dangers of higher interest rates, inflation approaching 4%, and a likely slowdown in AI capital spending.
