Investors often interpret analyst opinions from different angles — when companies have a low rank among analysts, it isn't necessarily the case that investors should conclude that the stock will perform poorly. It can, of course, but a bullish investor could also take the contrarian angle and read into the data that there is lots of room for upside because the stock is so out of favor. For these reasons, we at ETF Channel find value to putting together these rankings, because both the top and the bottom ends of the list can often make for some interesting stock picking ideas for further research.
