With today’s drubbing in US equities, the S&P 500 is coming dangerously close to finishing the second quarter in the red, which would end a streak of nine quarters in a row of gains (not including dividends). Going back to 1928, there have only been three other periods where the S&P 500 went nine or more quarters without a decline. Prior to the current streak of nine quarters during which the S&P 500 is up 45%, the most recent streak stretched 14 quarters from Q1 1995 through Q3 1998 when the S&P 500 was up 147%. That streak also proved to be the longest in the history of the index. There’s still another day left of trading to go in the quarter, and the dividing line between positive and negative returns (2,067.89) is right around current levels, so it could go either way, but given the fact that the S&P 500 has been down on the last trading day of every month since November (seven months), the prospects of a tenth straight week of gains aren’t bright.
