FYI:   The S&P 500 got off to a rough start to the year with a 3% decline in January.  The index has been straight up in February, though, and it's now up roughly 2% on the year.  
Where have we seen this action before?  Well, last year got off to a very similar start.  The index fell 2.93% in January, declined a couple of more days to start the month of February, and then it was straight up for the rest of the month.
Below is a chart showing the S&P 500's action through President's Day of both 2014 and 2015.
