Heads up, investors: Wall Street is starting to whisper about a possible 'lost decade' for US stocks. After years of big gains, some pros think the S&P 500 could be stuck in neutral for the next 10 years—meaning your 401(k) might not see the usual growth. Why? Stocks are pricey right now, and the market’s been on a wild run. If you’re thinking long-term, it might be time to peek at international funds or diversify your portfolio. #Business #Market #investing
