Largest Cumulative Stock Split Multipliers — Stock Rankings

Think of this table as a stock split history leaderboard ranked by a single number: we multiply every forward and reverse split ratio in our database—the same definition as the cumulative column on that ticker's Stock splits page (open it from the company profile). A 2:1 forward split contributes ×2; a 3:2 split contributes ×1.5. The product is a share-count adjustment chain: "how many times would one pre-split share have become today's share count" if you applied every event—separate from price charts, which are usually split-adjusted elsewhere. The Splits column counts how many split events each company has on record; sort by it to see which companies have split most often, a separate question from the largest multiplier.

Reverse stock splits (e.g. 1:10) enter as ratios below one and shrink the product. We only include rows where the ratio is positive; exchange-traded funds are excluded to match other company leaderboards. For the full mechanics, read cumulative split multiplier explained. This metric is not total return—for performance see returns since IPO or max return.
