The Invesco S&P 500 Equal Weight ETF (RSP) tracks the same S&P 500 index as the traditional market-cap weighted fund, but assigns nearly identical weightings to each of the 500 component companies. This egalitarian approach dramatically limits exposure to the largest stocks: the ‘‘Magnificent Seven’’ collectively represent close to 35% of the market-cap S&P 500, whereas in RSP each of those seven names accounts for roughly 0.18%–0.20% of the fund’s total weight. By capping any single holding at around 0.2%, RSP prevents a handful of mega-caps from dominating performance and volatility profiles.

Over the past decade, the market-cap weighted S&P 500 has delivered total returns of approximately 334%, outpacing RSP’s roughly 237% return. While the equal-weight ETF has underperformed in a strong bull run dominated by large tech stocks, its more balanced exposure can insulate investors against sharp drawdowns when mega-caps falter. Investors pay an annual fee of 0.20%, which is in line with similar large-cap strategies, but benefit from a built-in rebalancing mechanism that systematically sells winners and buys laggards, helping to lock in gains and maintain target sector allocations.

RSP’s sector weightings differ materially from the standard index: technology represents about 13.5% of the portfolio, compared with nearly 35% in the cap-weighted benchmark. Industrial, financial, healthcare and consumer staples sectors each command double-digit weights—ranging from roughly 10% to 16%—providing a broader cushion if tech or growth stocks suffer steep declines. This increased breadth can be particularly valuable in market corrections or crashes, as cyclical and defensive industries often exhibit lower volatility and more stable cash flows when large-cap growth names experience sell-offs.
