Wall Street's sour mood after its latest tumble could stretch into the New Year, says Bank of America technical strategist Paul Ciana. He has three top ideas to take advantage of the market's fearful tone heading into 2019.

Idea #1: Long the U.S. dollar, short the S&P 500

"Going back long term, the dollar versus the S&P as a ratio has a few significant bottoms that end up leading to a period where the dollar severely outperformed the S&P 500," Ciana said on CNBC's "Futures Now" on Thursday.
