Trader's big play on the FXE

In a week dominated by big-cap tech earnings, some traders are looking at two under-the-radar names that could see huge moves after they report.

The first of these names is Groupon. According to Susquehanna head of derivative strategy Stacey Gilbert, the e-commerce marketplace platform has an implied move of around 19 percent in either direction when it reports earnings Wednesday after the closing bell.

"Over the last eight quarters, it's moved around 18 percent and over the last 4 quarters around 26 percent," Gilbert said Friday on CNBC's "Trading Nation." "It's a known mover around earnings, and I would say the options market is suggesting that it could continue to be a big mover, even this quarter."

Looking just at this year, Groupon has moved massively off of its earnings reports. Last earnings quarter, Groupon jumped 25 percent after hours following its report in July and rallied to its year-to-date high in mid-August. The stock has fallen about 10.5 percent since then, but a positive Q3 earnings report on Wednesday could send Groupon shares rocketing once again, traders say.

The second name that could see big moves off earnings this week is C.R. Bard, according to "Crossing Wall Street" blog editor Eddy Elfenbein. C.R. Bard, a New Jersey–based medical device company, may not have seen as big of a jump off earnings as Groupon has in the past, but Elfenbein senses that C.R. Bard could climb after its earnings.

"In July when they gave their earnings guidance for Q3, it was $251 to $255, and I'm going to say right now that I think they're lowballing us," said Elfenbein. "I think they will beat that. I think they can go as high as $260 per share for Q3 and I think there's a good chance they'll guide higher for Q4 on sales and earnings."

C.R. Bard is up almost 16 percent year to date and will report earnings Tuesday after the bell.

This quarter's earnings have come in better than expected thus far. Per data from Thomson Reuters, of the 120 S&P 500 firms that have reported as of Friday's close 78 percent have beaten EPS estimates while 66 percent have beaten on revenues.

One notable outperformer thus far was Netflix. The stock surged by about 20 percent after hours following its positive earnings report last Monday.
