OEF: The Risks Are Still High For An Aggressive Approach

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.

OEF: A Simple Way To Beat SPY

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.

OEF: Best May Be Behind With Regime Change

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.
