"Top 3 ETFs to Consider Before Vanguard's S&P 500 ETF"

The Vanguard S&P 500 ETF is a popular choice for index fund investors, but there are alternative ETFs worth considering. The Invesco S&P 500 Equal Weight ETF offers diversification by investing equally across all S&P 500 constituents, reducing the influence of the largest companies. Investors may also want to explore small-cap stocks through ETFs like the SPDR S&P 600 Small Cap ETF and the Avantis US Small Cap Value ETF, which offer exposure to undervalued small-cap stocks with strong profitability characteristics. These alternatives present opportunities amid a heavily concentrated market.
