This beaten Asian market could be a buy

Time to buy Asian markets?

As Asian stocks have continued their slide, some traders suggest that now could be the time to wade back in to several markets in the region.

Chinese stocks have seen extreme drops recently, with the Shanghai composite index losing 37 percent in the last three months. Japan's Nikkei 225 index has fallen 12 percent in one month.

However, technical analyst Rich Ross of Evercore ISI says Japanese stocks have become a buying opportunity.

"All of that quantitative easing that we're seeing out of the [Bank of Japan], that's putting downward pressure on the yen, which makes Japan more attractive." Ross said Thursday on CNBC's "Trading Nation."

Ross recommended using the WisdomTree Japan Hedged ETF, DXJ, to protect against additional currency risk when investing in the Nikkei with the yen. The DXJ has hit a low not seen since 2014, which Ross said signals opportunity for investors.

Hedged ETFs replicate the performance of a long-stock, short-currency strategy, which would alleviate concerns for U.S. investors about a continued decline in the value of the yen against the dollar.

More generally, while emerging markets have suffered in the past year, Larry McDonald of Societe Generale said they could be a good long-term investment.

"They may have some rougher roads ahead, but if you look at total market capitalization versus GDP, emerging markets are trading 50 to 60 percent cheaper than the U.S.," McDonald said.

Emerging markets such as Brazil, Thailand, Vietnam and others have been dealt blows by weakening currencies, lower commodity prices and an economic slowdown in China. The iShares MSCI emerging markets ETF (EEM) has fallen more than 15 percent this year, despite a 3 percent rally this week.

However, McDonald said credit markets continue to paint a bearish picture in the short term.

"The cost of default protection has to come down before equities bounce," he said Thursday on "Trading Nation." But "if you want to take a nibble in here, great."
