What I'd really like to see would be trails going off into the future -- rather than just a +/-% for the +3yr mark, why not just show the whole story for each company (perhaps only when you hover over it to avoid clutter). This would make the current color-coding much more useful -- each trail would be the color of the company's IPO year.
