iShares S&P 100 ETF

OEF

Market cap $26.8B

The popularity of ETFs continues to surge this year. And investors definitely have a type they prefer.

Inflation rose in August, but jobless claims rose, too, shaping Fed rate cut odds and boosting the appeal of large-cap blend ETFs like ITOT, EDOW and IVV.

Mega and large cap stocks continue to outperform, driven by robust earnings growth, especially in tech, financials, and healthcare sectors. OEF provides diversified access to the 100 largest S&P 500 companies, balancing mega cap upside with lower risk than more concentrated ETFs. OEF has consistently outperformed the S&P 500 over multiple timeframes, with strong price momentum, healthy liquidity, and a competitive expense ratio.

OEF offers concentrated exposure to the largest S&P 500 companies, with high tech weighting and elevated idiosyncratic risk versus broader market ETFs. Current valuation and sector concentration make OEF more vulnerable to pullbacks, especially in risk-off environments and amid waning market momentum. While OEF's long-term returns are similar to peers, it has underperformed SPY, questioning the benefit of its higher concentration.

Launched on October 23, 2000, the iShares S&P 100 ETF (OEF) is a passively managed exchange traded fund designed to provide a broad exposure to the Large Cap Blend segment of the US equity market.

OEF surges to a 52-week high, gaining 33.6% off its low as large-cap stocks ride market highs and rate-cut hopes.

Designed to provide broad exposure to the Large Cap Blend segment of the US equity market, the iShares S&P 100 ETF (OEF) is a passively managed exchange traded fund launched on 10/23/2000.

OEF offers a simple, effective strategy by focusing on the largest 100 S&P 500 companies, leading to strong historical outperformance versus SPY. The ETF's heavy technology sector weighting and concentration in top performers drive returns, though they introduce some concentration risk. Despite a higher expense ratio than IVV, OEF's focus on winners and automatic removal of laggards make it a compelling choice for long-term investors.

If you're interested in broad exposure to the Large Cap Blend segment of the US equity market, look no further than the iShares S&P 100 ETF (OEF), a passively managed exchange traded fund launched on 10/23/2000.

The iShares S&P 100 Index Fund ETF (OEF) has outperformed the SPY but primarily due to a few top-performing stocks, not broad strategy. Risk-adjusted returns and backtesting show OEF's outperformance, but the excess returns lack statistical significance, driven by a concentrated few. Forward simulations indicate OEF underperforms the SPY, suggesting the outperformance is not sustainable under different market conditions.
