This month, the bull market celebrates its sixth anniversary with the S&P 500 up over 200% during that period. Just how extraordinary is that run? Societe Generale analyst Andrew Lapthorne illustrates it by charting the rolling six-year return in the S&P 500 since 1907. "Such a strong six year run up in US equities has only been seen twice since 1900, i.e., back in 1929 and 1999, neither of which ended well," Lapthorne wrote.
