Top Analyst Upgrades and Downgrades: AcelRx, Alcoa, Costco, Lululemon, Walmart, Trulia and More

Stocks were indicated higher on Tuesday morning despite sanctions in Russia. Investors still want upside from their investments, but they seem to be looking at individual companies and sectors rather than the broad market as a whole. 24/7 Wall St. reviews dozens of analyst research reports each morning of the week to find new investment and trading ideas for our readers. Some analyst reports cover stocks to buy. Others feature stocks to sell or stocks to avoid.

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

AcelRx Pharmaceuticals Inc. (NASDAQ: ACRX) already took at least one downgrade on Monday as its stock fell 41% after the FDA rejected its pain device. Now on Tuesday it was downgraded to Neutral from Overweight at Piper Jaffray.
