Largest Cumulative Stock Split Multipliers — Stock Rankings
Companies ranked by the product of every historical split ratio in our database—active listings, ETFs excluded.
What “cumulative split multiplier” means
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.
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.

Frequently asked questions
What is a cumulative stock split multiplier?
- It is the product of every split ratio (numerator ÷ denominator) recorded for a ticker in our database. A 2:1 split multiplies by 2; a 1:10 reverse split multiplies by 0.1. The result describes how many times share count would have scaled if you chained every event—separate from price charts, which are usually split-adjusted.
How is this different from a stock split history page?
- Each company profile has a Stock splits timeline with per-event ratios and the same cumulative column. This ranking sorts companies by that final cumulative value so you can compare tickers on one leaderboard.
Do reverse stock splits count?
- Yes. Reverse splits use a ratio below one, so they reduce the cumulative product. Only rows with a strictly positive ratio are included in the product.
Does a high multiplier mean the stock went up?
- No. Splits change share count and nominal price; they are not a performance metric. For returns, use rankings such as best performing stocks since IPO or max return.
Data & methodology
How is the multiplier computed?
- For each symbol we multiply every qualifying split ratio from our fmp_splits table. Qualifying means denominator is non-zero and the ratio is positive. Multiplication order does not change the product.
How often is the ranking updated?
- The page reads the latest split rows in the database. When new splits are ingested, the leaderboard and “through” date reflect the newest qualifying event dates among listed companies.
