Top Analyst Upgrades and Downgrades: Eli Lilly, Enphase, Lululemon, SodaStream, Yelp and More

Stocks were lower on Thursday after weak overseas trading. Investors are braced for Friday’s key unemployment and payrolls report, and they are still looking for upside from their investment funds. 24/7 Wall St. reviews dozens of analyst research reports each morning, hunting for new investment and trading ideas for our readers. Some of the analyst calls cover stocks to buy, and others are about stocks to sell or stocks to avoid.

These are this Thursday’s top analyst upgrades, downgrades and initiations from Wall Street firms.

AllianceBernstein Holding L.P. (NYSE: AB) was raised to Buy from Neutral at Citigroup.

Buffalo Wild Wings Inc. (NASDAQ: BWLD) was raised to Buy from Neutral with a $176 price target (versus a $145.17 close) at Sterne Agee. Keep in mind that this upgrade is on the heels of a 13% post-earnings drop.

Cliffs Natural Resources Inc. (NYSE: CLF) was raised to Market Perform from Underperform at Bernstein.

Ecolab Inc. (NYSE: ECL) was raised to Overweight from Neutral at J.P. Morgan.

Eli Lilly & Co. (NYSE: LLY) was downgraded to Neutral from Buy at Citigroup.
