A corporate action that increases the share count and proportionally lowers the price per share, leaving total value unchanged.

Formula

New Shares = Old Shares x Ratio; New Price = Old Price / Ratio

What it is

A stock split divides each existing share into more shares, for example two new shares for each old one in a 2-for-1 split. The price per share drops in proportion, so an investor's total holding is worth the same immediately after. It changes the number and price of shares, not the value of the company or your stake.

Why it matters

Splits are mostly cosmetic, often done to make a high-priced stock look more affordable and improve liquidity. The pitfall is treating a split as good news about fundamentals; it adds no value, and historical price charts and per-share metrics must be split-adjusted to compare correctly across time.

How it's calculated

Apply the split ratio: multiply the share count by the ratio and divide the price by the same ratio. A 3-for-1 split triples the shares and cuts the price to one-third.

How Quintarthai uses it

Each company's deep-analysis page has a dedicated Stock Splits tab showing its split history in the app.

Cross-border note. A US-listed and TSX-listed dual listing of the same company splits on both exchanges together, but the resulting per-share prices stay denominated in each listing's currency (USD vs CAD).

FAQ

Does a stock split make me richer?

No. You own more shares at a proportionally lower price, so the total value of your position is unchanged at the moment of the split.

Do my per-share metrics change after a split?

Yes, figures like earnings per share and historical prices are restated on a split-adjusted basis so comparisons over time remain valid.
