"neutral", "market perform", and "sector perform" are the code words for "sell" From the looks of X action yesterday, being moved from "conviction buy" to "buy" is also a code word for "sell".
Here's the cliff's note to analysts' ratings: http://www.finra.org/Investors/Smar...nderstandingSecuritiesAnalystRecommendations/
Market perform is a stock within +/- 10% of the future, or some other percentage depending on which firm made the call. Sector perform is within 10% of the benchmark's sector. Market outperform is exceeding the market by 10+%. Market underperform and the stock is predicted to underperform by 10% to the market. Strong buy is an absolute price call beating the market by at least 10% over 6-18 month periods. Generally these are all relative to benchmarks, but it depends on the analyst and who they're with.
