The Stock Market Is on the Brink of Doing Something That Hasn't Been Observed Since 1871 -- and Even Wall Street Analysts Are Worried

The S&P 500's Shiller P/E Ratio has reached 42.84, the second-highest valuation since 1871 and just 3.5% away from the dot-com bubble peak of 44.19. Bank of America Securities warns that the market is 'statistically expensive on 17 of 20 metrics' with 70% of bear market signals triggered, suggesting investors should take profits. However, historical data shows that despite market corrections, all 107 rolling 20-year periods of S&P 500 returns since 1900 have been positive, favoring long-term investors.
