Citi analyst Lucio Aldworth sees several reasons why eBay's (EBAY) sale of a majority of its stake in MercadoLibre (MELI) creates a "large overhang" on the latter's shares. Namely, he believes the market has always seen eBay as a plausible candidate to take over MercadoLibre, but he thinks this action should remove any M&A premium currently priced into the stock. Additionally, Aldworth notes that eBay said its commitment to Latin America e-commerce remains unchanged, which could mean it will eventually enter the market directly, intensifying competition for MercadoLibre. Aldworth keeps a Sell rating on MercadoLibre shares, which are down 8% in early trading to $168.40.

DZ Bank upgraded MercadoLibre to Buy from Hold with a $1,685 price target.
