Trades outside the equity market could prove more lucrative if a strengthening dollar brings volatility to stocks, CNBC “Fast Money” trader Pete Najarian said.

“People are definitely concerned as this dollar strengthens,” Najarian said.

The euro hit a 12-year low against the dollar (Exchange: EUR=) on Tuesday as the three major U.S. indexes each shed more than 1 percent. The dollar index (Exchange: .DXY)-which measures the greenback against a basket of currencies-jumped more than 1 percent to close just below $ 99.

The index is “probably a buy” right now, Najarian said. Options in the CBOE Volatility Index (INDEX: .VIX)-which measures expectations for market uncertainty-also look appealing if choppy trading continues, he added.

It spiked more than 10 percent on Tuesday to sit below $ 17.

Some stocks should prove resistant to a strong dollar, trader Karen Finerman said. She bought calls in United Rentals (NYSE: URI), which fell more than 4 percent to $ 87 per share on Tuesday.

It holds upside as it conducts most of its business in the U.S., Finerman said.

“It’s almost immune to [a strong dollar],” she said.

Trader Steve Grasso looked at E-Trade Financial (NASDAQ: ETFC) and Charles Schwab (NYSE: SCHW), which he called “interest-rate speculative plays.” He believes the stocks will climb higher “in what should be a rate increase sooner or later.”

E-Trade and Schwab both lost ground on Tuesday, closing around $ 27 and $ 30 per share, respectively.
