China is home to more than its fair share of red-hot foreign stocks. But names from Russia and Latin America also are appearing on growth investors’ radars.

Yandex (YNDX ) is Russia’s dominant search engine, commanding more than 60% of that country’s market share. Yandex shares, however, have become extended above their 10-week moving average, so investors should wait for a new entry.

That test appeared in much the same way as those of other leaders. A high-volume sell-off Oct. 8 saw it rush to the 10-week line, which held fast. The next day it not only found support but reversed higher.

Yandex has been rising from that support in active trading.

U.K.-based chip designer ARM Holdings (ARMH ) rose on Wednesday from its 49.45 cup-with-handle buy point. However, volume was slightly below average, making the breakout suspect.

The company made headlines recently when Apple revealed that its new iPhone 5S is powered by ARM’s 64-bit chip. Thirty-two bits had been the industry standard, but ARM seems to be raising the bar.

If the iPhone has a 64-bit chip, why can’t Samsung, HTC or LG keep up?

They may have to. More bits mean more speed, which is crucial in the scramble for smartphone market share. ARM has a near-lock on the market for smartphone chips, and it earns higher royalties on the 64-bit chips than on the 32-bit chips.

E-commerce company MercadoLibre (MELI ) also is rising from its 10-week line. The stock managed to rise just 6% from a buy point at 132.95 before falling victim to the broad market’s swoon Oct. 8- 9.

The stock sank as much as 6.4% below its cup-with-handle buy point Oct. 9 not enough to trigger the 8% sell rule, but enough to scare out many longs in such an unnerving environment.

That session ended with MercadoLibre in the upper 60% of the day’s trading range, while volume swelled well above average. This positive behavior also saw MercadoLibre regain its 10-week line, which put the stock in a secondary buy area.

MercadoLibre is a sort of Latin American eBay. It’s based in Argentina but earns more than half its revenue in Brazil.

One final note: While many non-Chinese leaders are doing well for their shareholders, they have been lagging their Chinese peers the past few months.

Look at a weekly chart of Yandex. Now, fast, punch up China’s Qihoo 360 Technology (QIHU ).

Compare MercadoLibre with Vipshop (VIPS ). Now look at SouFun (SFUN ) and Zillow (Z ). One sees a pattern.
