NEW YORK ( TheStreet) -- Three ETFs that provide exposure to Southeast Asian countries, iShares MSCI Malaysia Index ( EWM), MarketVectors Indonesia ( IDX), and iShares Thailand MSCI Investable Market Index ( THD), are all approaching their 52-week highs, drawing attention to the funds' impressive track records over the past year.The leader of this group, IDX, is up by about 60% in the past year. Although impressive, THD and EWM lag slightly behind with gains of roughly 45% and 30% in the past year. Each of the funds endured a difficult month of May, as did markets elsewhere in the world, but after those losses, IDX and EWM snapped back, approaching their recent highs. While U.S. markets were probing new lows in June, these ETFs were already in a resumed uptrend. THD is the weakest of the three right now -- though still within 5% of its highs for the year -- because political instability has weighed on shares. Political turmoil caused Thai stocks to drop in early April and continue lower as prolonged political demonstrations turned violent in the heart of downtown Bangkok. However, the political situation did not deteriorate and THD actually held up better than most ETFs during the May sell-off. Prior to the drop-off in Thai markets, shares had been moving steadily higher, helped by attractive valuations that lured foreign investors. Currently, the political situation has stabilized, but the ruling party faces a court challenge to its very existence because opponents have filed a court case seeking to ban the party. THD remains steady though, as investors focus on the value in the Thai market. Looking at these funds in comparison to other Asian markets also shows the extraordinary way in which they have performed over the previous three months. iShares MSCI All Country Asia ex Japan ( AAJX), a fund with 27% of assets in China, 18% in South Korea, 14% in Taiwan, 11% in India, and 11% in Hong Kong, has fallen 6.8% in the past three months, but IDX, EWM and THD have returned 1.4%, - 0.55% and 4.7%. Investors have reason to continue to be bullish on THD, EWM, and IDX, in light of the recent decision by the Chinese government to allow the yuan to appreciate against the U.S. dollar.
