Stocks were indicated higher on Wednesday ahead of the pending FOMC decision on interest rates. Tuesday’s rally was yet another instance where investors proved that they want to buy stocks after every stock market sell-off. 24/7 Wall St. reviews dozens of analyst reports each morning to find new trading and investing ideas for its readers. Some analyst reports cover stocks to buy, and other analyst calls cover stocks to sell or stocks to avoid.

These are this Wednesday’s top analyst upgrades, downgrades, and initiations.
