Every day, the sun rises on Wall Street, and a plethora of professional analysts wake to issue new opinions on stocks. Here at the Fool, we use our "This Just In" column to examine some of these picks-- and the track records of the banks behind them -- so individuals can make better investing decisions.

In addition to following professional banks, anyone can use Motley Fool CAPS to monitor the collective opinions of more than 150,000 members, many of whom demonstrate better investing insight than published analysts do.

After holding a three-star rank for the past several months, enough top-performing CAPS members have turned bullish on MercadoLibre (Nasdaq: MELI) recently to upgrade it back to a more formidable four stars. A total of 829 members have given their opinion on the online trading firm, with many of them offering analysis and commentary explaining the recent optimism.

As global markets claw their way toward some sense of normalcy, CAPS members like the long-term prospects for MercadoLibre and its position in emerging markets. MercadoLibre is often described as the Latin American eBay (Nasdaq: EBAY), and investors see big growth potential for the company as more consumers make online purchases.

While Amazon.com (Nasdaq: AMZN) and traditional retailers like Wal-Mart Stores' (NYSE: WMT) walmart.com continue to show amazing growth in the U.S., MercadoLibre is focused on countries to the south and recently knocked down another quarter of strong growth. It reported a 47% sales increase in the fourth quarter, with full-year 2009 earnings jumping 77% over 2008. The company sold 47% more items on its site, the seventh consecutive quarter of accelerating growth in this metric.

MercadoLibre's payments business, similar to how PayPal facilitates Visa (NYSE: V) and other online payments, saw transactions more than double over the prior year. Such rapid growth always lures in competition from big sharks, of course, but MercadoLibre shows no sign of letting up, as the stock's big run in the past year has outpaced that of other Internet stocks like Google (Nasdaq: GOOG) or Yahoo! (Nasdaq: YHOO).

The lofty premium that MercadoLibre shares have commanded led to a sizable sell-off recently, but many investors are looking further into the future and see big, long-term potential.
