Stock Dividends and Bonus Issues

A stock dividend (called a bonus issue in many non-US markets) is a company handing out extra shares to existing holders instead of cash — for example, a "1-for-10" bonus issue gives you one new share for every ten you already own. Unlike a cash dividend, no money leaves the company and no money arrives in your account. Instead, the same underlying pie of company value gets sliced into more pieces, so each share is worth proportionally less. If a stock trades at $110 and the company declares a 1-for-10 stock dividend, a holder of 100 shares receives 10 more shares (110 total), and the price adjusts down to roughly $110 x 100 / 110 = $100 per share. Before and after, the position is worth $11,000 — nothing has actually changed except how finely it's divided.

Companies do this for a few practical reasons: it lets a firm signal confidence or reward shareholders without spending cash that might be needed for operations, and it can bring a high share price down into a more "retail-friendly" trading range, similar to a stock split. Tax treatment differs by jurisdiction, but in most cases a pure stock dividend of this kind is not treated as taxable income, since the shareholder hasn't received any new economic value — only more, smaller slices of the same thing.

For someone tracking a position, the key operational point is that historical price and volume data must be adjusted retroactively for the bonus ratio, or a stock dividend will look like a price crash on a chart when nothing actually happened to the company's value.
