What Is a Stock Split?

A stock split multiplies the number of a company's outstanding shares by a fixed ratio and divides the share price by that same ratio, so the total value of the company, and of any single investor's holding, does not change at the moment of the split.

How it works#

In a 2-for-1 split, one existing share becomes two, and the price per share is roughly cut in half. In a 10-for-1 split, one share becomes ten and the price per share drops to roughly a tenth of what it was. Nothing about the company's revenue, profit or assets changes; only the number of slices the same pie is cut into changes.

Companies announce a split with a declaration, then a record date and an effective date, similar in structure to a dividend's timeline. Existing shareholders receive the additional shares automatically in their brokerage account on the effective date; no action is required and nothing is bought or sold.

A real example#

Monster Beverage Corporation completed a 2:1 forward stock split effective August 11, 2026. Every 1 share held before that date became 2 shares, and the share price was roughly cut in half on the split date, matching the ratio exactly. A shareholder who held 100 shares worth $60 each the day before, $6,000 total, held 200 shares worth roughly $30 each the day after, still $6,000 total, before the stock moved for any other reason.

The board had declared the split about a month earlier, on July 8, 2026, with a record date of July 24, 2026, so the mechanics played out over roughly five weeks from announcement to the shares actually showing up split-adjusted in accounts. That gap between announcement and effective date is typical; it gives brokers and exchanges time to update systems before the new share count and price go live for every holder at once.

Forward splits, reverse splits and why companies do either#

Everything above describes a forward split, the common kind, usually done when a company's share price has climbed high enough that management believes a lower, more familiar-looking price will be easier for smaller investors to trade in round numbers. A reverse split runs the opposite direction: a company reduces its share count and proportionally raises its price, often because the price has fallen low enough to risk delisting from an exchange that sets a minimum bid price, or simply to look less like a distressed stock. Beyond Meat's 2026 reverse split, a 1-for-30 combination that multiplied its share price by 30, was explicitly framed around staying above Nasdaq's $1.00 minimum listing requirement rather than any change in the underlying business.

Neither type of split, by itself, is a signal about business quality. It is a signal about what the board believes the share price needs, cosmetically, at that specific size.

Common misreadings#

The most common misreading is that a split makes a stock "cheaper" in any meaningful sense. The company is worth exactly what it was worth the day before; a lower per-share price just means each share represents a smaller slice of the same pie. A second misreading treats an upcoming split as inherently bullish. The market sometimes bids a stock up ahead of an announced split on the expectation that other investors will buy in once the price looks more approachable, which is a bet on other people's behavior, not a bet on the business getting better.

Related terms#

A reverse stock split is the mirror image of everything above, usually triggered by a struggling share price rather than a rising one. EPS and market cap both look different after a split purely because the share count changed, even though nothing about the company did.
