Santa Claus rally on the way?

October's stock market treats could be December's tricks, at least if end-of-the-year historical trends hold up.

After a brutally volatile year, equities have soared this month, with the up nearly 8 percent as of Monday trading. That has brought the broad stock market gauge just into positive numbers for 2015 and more than 11 percent off its low back in August.

Such violent rallies often come with a price, though: In this case, it's a tendency to follow such big shows with lackluster second acts.

Sam Stovall, U.S. equity strategist at S&P Capital IQ, said market participants should get ready for some Christmastime coal after Halloween candy.
