How to read this ranking
52-Week Gain is the column the table is ordered by: the percentage change from the split-adjusted close one year ago to the latest close. Because the prices are split-adjusted, a split inside the window contributes nothing to the figure, and a company that split three-for-one shows the return its holders actually earned rather than a two-thirds fall.
Start Close is the split-adjusted close a year back that the gain is measured from, dated. Market Cap and Price describe the company as it is today. A gain of several hundred percent takes far less buying on a small company than on a large one, so small companies can reach the top more easily, but large companies appear there too.
The board admits companies above $100 million in market capitalization listed on NYSE, Nasdaq and NYSE American, with no liquidity test and no price minimum. It leaves out preferred shares and other non-common equity, price histories with a gap of more than 30 days, symbols held for a data review, and symbols this site does not publish. A company needs a close a full year back to be measured at all, which is why a recent listing is absent here while it appears on the year-to-date board. Country and Sector come from each company's own record and are what to check first when a symbol near the top is unfamiliar.
