Oppenheimer views last week’s rally in small-cap stocks as a potential catalyst for the wider market and its future returns. “While small-cap returns have been marginally higher following this signal, the S & P 500 currently exhibits a stronger relative trend and a higher weighting toward this cycle’s leadership,” said chief market technician Ari Wald in a note to clients Saturday. “The point is that last week’s small-cap breakout marks a re-broadening of the bull that should carry bullish implications for all capitalizations.” Wald added that weekly small-cap rallies exceeding 5% since 1979 have culminated in above-average returns for the S & P 500 and Russell 2000 over the course of the following one-, three-, six- and 12-month periods. .RUT YTD mountain Performance in 2024 The comments from Wald came on the heels of last week’s 6% surge in the Russell 2000 index of small caps. The iShares Russell 2000 ETF added as much as another 1.6% early in Monday’s session. Many on Wall Street have come to view the small-cap trade as a potential winning strategy this year.

Given this outlook, Oppenheimer reiterated some of its top small- and mid-cap stock picks that could benefit from secular trends, including the rise of artificial intelligence and obesity drugs. The picks included Viking Therapeutics and marketing technology provider Zeta Global . “In our view, this cycle’s ‘as good as it gets moment’ has not yet been reached,” Wald said.
