How to read this comparison
Neither column is a verdict. Market cap tells you size, not value. The sentiment score describes how a stock is currently behaving relative to its own history and its peer group — a high score often reflects a large recent move rather than an opportunity. Because these two compete in the same segment, relative strength is the more informative line: it strips out the move the whole group made.
