As of Tuesday, the S&P 500 was down for the year, hitting it's lowest level since early March.
But as for where stocks finish this year, maybe you shouldn't worry just yet.
JPMorgan Asset Management just published its new quarterly markets guide, and one of the things they show is that stocks usually go down within calendar years, but more often than finish the same year higher.
The chart below shows that over past 35 years, the S&P has had positive annual returns in 27 - or 77% - of those years. But in 19 of those year, the peak-to-trough move has been in excess of 10%.
So, while stocks are selling off amid uncertainty in the markets, we could still see 2015 end with positive returns - in fact, we're more than likely to.
