“With just two trading days left in 2014, it’s mathematically assured that the S&P 500 will finish the year without ever having four consecutive down days. That’s never happened before in the 90 or so years since Standard & Poor’s launched its first stock index in the 1920s. (The S&P 500 in its current form dates to 1957.)

What’s more, there were barely any instances of three-day slides for much of the year. Before Labor Day, there were just four such three-day streaks, a startling testament to the lack of market volatility for large swaths of 2014.

But in the last few months, that’s changed. Since Labor Day, there have been six three-day slides, including twice earlier this month. But every time, day four was an up session.

In contrast, 2014 has brought us 11 winning streaks of at least four days, including the five-session run which ended with a 0.29-point decline on Christmas Eve.

The last four-day drop for the index was capped on Dec. 13, 2013. Even then, the S&P 500 barely notched a four-session skid, as the index that day logged a mere 0.18-point decline.“. – by Kevin Kingsbury of Morning Money Beat
