A share consolidation is when a company decreases the total number of shares it has in the market, by increasing the value of each share it has there. This means that if you’re a shareholder, you’ll have fewer but more valuable shares.

A stock split is sort of the opposite of a share consolidation. It’s when a company increases the number of its shares in the market by proportionally decreasing its share value. So if you’re a shareholder of a company which does this, you’ll have more shares but the value of your investment is the same as before the stock split.

When either a share consolidation or stock split happens on one of your investments, you’ll get a corporate action notification to let you know this and your shares will be replaced with the new number – which’ll total the same investment value as before the corporate action.
