If the Market Rally Stalls, This ETF Can Insulate Portfolios

The article warns that the S&P 500 rally is highly concentrated in mega-cap tech names and suggests the Invesco S&P 500 Equal Weight approach (RSP) can insulate portfolios if the rally stalls. RSP recently hit an all-time high and offers lower technology exposure (≈19% vs. SPY’s ≈38%), a lower beta (0.92), higher yield (1.50% vs. SPY’s 0.98%) and roughly $88.8 billion AUM. While equal-weight funds may cap upside versus cap-weighted ETFs during concentrated rallies, they historically reduced downside and have outperformed the cap-weighted S&P by about 1.0–1.05% annualized since 1990. The piece frames RSP as a more defensive alternative to the market-cap S&P 500 for investors worried about concentration risk and an overdue pullback, while noting modest short-term relative underperformance during the current rally.
