How stocks pay you
Splits, groupings and bonus shares
4 min
Sometimes the number of shares you own changes overnight — without you buying or selling anything. Three corporate actions cause this, and none of them, on their own, makes you richer or poorer.
Stock split (desdobramento)
A split divides each existing share into more shares. In a 2-for-1 split, every 1 share becomes 2, and the price per share is halved. If you held 100 shares at R$ 80, you now hold 200 shares at R$ 40 — the same total value of R$ 8,000.
Why do it? A lower price per share can make the stock feel more accessible and improve liquidity for small investors.
Reverse split / grouping (grupamento)
A grouping is the opposite: shares are combined and the price rises proportionally. A 1-for-10 grouping turns 100 shares at R$ 1 into 10 shares at R$ 10 — again, the same total value. Companies often do this to lift a very low share price off the floor.
Bonus shares (bonificação)
A bonus issue (bonificação) hands existing shareholders extra shares for free, usually by converting accumulated reserves into capital. You end up with more shares, but each is worth a little less, so your total stake is essentially unchanged at the moment it happens.
The mindset
The common thread: these actions reslice the same pie, they do not add filling. Do not confuse "more shares" with "more wealth." What matters is the total value of your holding and the company's underlying performance, not the share count.
