SPY is market-cap weighted, meaning the largest companies have the biggest influence on the index. RSP, the equal-weight S&P 500, gives the same stocks a much more balanced weighting. Put the two charts side by side and you can see two very different pictures of the same 500 companies.That difference matters because the biggest companies can keep the S&P 500 looking strong even when participation underneath the surface is weak. At one point discussed in the video, more than half of the S&P 500 was below its 200-day moving average, while the index remained close to its record high.We also look at MMFI and MMTH, which measure how many stocks are above their 50-day and 200-day moving averages. These indicators provide another way to see whether the market's strength is broad or concentrated in a relatively small number of stocks.The discussion also gets into mega-cap concentration and portfolio diversification. If several ETFs own many of the same giant companies, owning multiple ETFs doesn't necessarily mean you have multiple independent exposures. You could unknowingly be increasing your exposure to the exact same stocks.The bigger lesson isn't that SPY is bad or that RSP is automatically better. It's understanding what you actually own, why it behaves differently, and how much of your portfolio depends on US mega-cap stocks.✅ SPY vs. RSP and the equal-weight S&P 500✅ S&P 500 concentration and mega-cap stocks✅ Market breadth, MMFI and MMTH✅ Why your portfolio can lag the S&P 500✅ ETF overlap and true portfolio diversificationIf you've ever wondered why the S&P 500 is doing great while your portfolio isn't, this may explain what's happening beneath the surface.Subscribe to OVTLYR for disciplined trading strategies that actually make sense. 👉 https://www.youtube.com/@ovtlyrdotcom#SPY #RSP #SP500 #StockMarket #OVTLYR #MarketBreadth #S&P500 #EqualWeight #MegaCapStocks #PortfolioDiversificationHere's how we plan to DOMINATE the US Investing Championship for 2026You can see our step by step trading plan developed by a team of over 20 quants for FREE by clicking here: https://www.ovtlyr.com/usicplan
