What is a stock split?

A stock split increases the number of shares each existing investor holds by dividing each share into multiple new shares, while reducing the per-share price proportionally. In a 3-for-1 forward split, every share becomes three new shares and the per-share price is divided by three. The company's total market capitalization, the holder's aggregate position value, and the holder's ownership percentage are unchanged by the split itself — only the unit of denomination changes.

Forward splits are most often executed by large-cap companies whose share price has risen high enough that the headline number becomes a friction point for retail buyers (e.g. Apple's 4-for-1 split in 2020 at ~$500, Nvidia's 10-for-1 split in 2024 at ~$1,200). The mechanical effect is purely re-denomination; the post-split market reaction is its own thing and typically modest.

What is a reverse stock split?

A reverse stock split reduces the share count by combining multiple existing shares into one new share, with the per-share price increasing proportionally. A 1-for-10 reverse split turns ten old shares into one new share at ten times the prior price. Like a forward split, the reverse split is a re-denomination — market cap, total position value, and ownership percentage are unchanged at the moment of the split.

The dominant driver of reverse splits on US exchanges is continued-listing bid-price compliance. Both Nasdaq and NYSE require listed common stock to maintain a closing bid above $1. After a sustained drop below the threshold, the exchange issues a deficiency notice with a cure period — typically 180 days, extendable in some cases. A reverse split is the fastest mechanical way to lift the bid back above $1 without needing operating-performance recovery. As a result, the majority of US reverse splits are filed by micro-cap and small-cap issuers; large-cap reverse splits are rare and usually signal a major capital-structure or spinoff event.

Ratio mechanics and ex-date vs. effective date

The split ratio is the most important field on this page. A 3-for-1 forward split means every one share becomes three. A 1-for-10 reverse split means every ten shares become one. Wiseek normalizes ratios to a standard "X-for-Y" form; non-standard or fractional ratios are flagged with "(approx)" so traders can verify against the filing.

Two dates matter: the record date is the cutoff that determines which holders are entitled to the split, and the effective date (also called the ex-split date) is the trading day on which the security trades at the new post-split price and the new share count is reflected in brokerage accounts. The dates shown in the tables above are effective dates. Some exchanges also publish a separate "payable date" which is operationally similar to the effective date for splits but may differ for stock dividends.

Frequently asked questions

How does a split affect my brokerage account?

Brokers automatically adjust share counts and cost basis on the effective date — no action is required from the investor. Open limit orders and stop orders are typically cancelled around the split and must be re-entered at the post-split price. Fractional shares resulting from a reverse split are usually cashed out at the closing price on the effective date, since most US brokers do not hold fractional shares of all securities.

Does a stock split change a company's market capitalization?

No. A split is purely a re-denomination of existing equity. Market cap equals share price multiplied by shares outstanding, and a split changes both proportionally and in opposite directions, leaving the product unchanged. Subsequent market reaction can move the price, but the split itself is mechanically value-neutral.

Why do so many small companies do reverse splits?

The single largest driver is exchange listing compliance. Nasdaq and NYSE both require listed common stock to maintain a closing bid above $1. After a sustained drop below that threshold, exchanges issue a deficiency notice with a cure period (typically 180 days, extendable). A reverse split is the fastest mechanical way to lift the bid price back above $1 without needing to drive operating performance. As a result, the great majority of reverse splits on US markets come from small-cap and micro-cap issuers managing listing compliance rather than large-cap companies.

Is a forward split a buy signal?

Splits are not earnings events and do not change fundamentals. Some academic studies have found small post-split outperformance for large-cap forward splits, attributed to signaling (management confidence) and retail accessibility (lower per-share price), but the effect is modest and not robust across periods. Wiseek does not treat splits as standalone trading signals; they appear in this calendar as an informational data point and link out to each ticker's filings page for context.
