With the S&P 500 currently up 15% year-to-date, we’d basically need to see a market crash for the index to close down on the year when all is said and done on December 29th, 2017 (the last trading day of the year).  If the market doesn’t crash, the S&P will likely go the entire year without trading into negative territory at any point.

As shown below, there have only been ten prior years where the S&P went the entire year without trading into negative territory.  The last two were relatively recent in 2012 and 2013.  What’s notable in the table is the performance in the following year after the S&P goes an entire year “in the black.”  Following the ten prior occurrences, the index traded up the next year nine times and down just once.  On average, the next-year gain was +12.52%.  Investors would surely sign up for another 10%+ gain in 2018!
