This Is Warren Buffett's Favorite Index Fund, and It Could Turn $200 per Month Into $1 Million

The article reiterates Warren Buffett’s long-standing endorsement of an S&P 500 index fund as a simple, diversified path to long-term wealth. Using historical averages (about 10% annual return) and illustrative compounding scenarios, it shows how a $200/month investment could grow to roughly $1 million over multi-decade timeframes (depending on assumed returns and horizon). The piece highlights the trade-off: S&P 500 funds track the market rather than beat it, offering stability and broad diversification but potentially lower upside than concentrated growth strategies. It underscores historical resilience (every 20-year period positive per Crestmont) and promotes passive, time-in-market investing as a market-impactful strategy for individual investors.
