Top Stocks by Max Return

We rank stocks by historical max profit: the single best buy date and sell date in our price series, expressed as total return with perfect hindsight. It is a theoretical upper bound for comparing how far a price has run between a trough and a peak—not a return you could plan to capture in advance.

Unlike return since IPO (buy at listing, hold to today), max profit can start after the IPO and uses whichever dates maximize the gain. Useful for seeing how volatile a name has been; not a realistic investing outcome.
