Who gained and lost the most market cap
Market cap is shares on issue multiplied by the share price, so a 4% week at a large producer can be worth far more money than a 60% week at a small explorer. These boards rank ASX mining and healthcare companies by the dollars their market cap moved over the week, the month, the quarter and the year — not by percentage, which the home page already shows.
Open any company for its news-flow record — every market-sensitive announcement it has filed this year, against its price.
Market cap is shares on issue × close — what the whole company is worth. Ranked by the A$ change across the last 5 trading sessions, A$250k+ traded over the period. Rows marked * are measured on today’s share count, so they are what today’s shareholders gained or lost on the price — not the company’s change in market cap.

* Every figure here is measured on today’s share count. We began banking a dated share count each trading day on 15 August 2026; as that record fills, these become true changes in market cap — the weekly board first, the yearly board last.
A company that issues new shares is worth more money without anybody having paid more for it. Where we know the share count at both ends of a window, the figure above is the true change in market cap and the row says so; where we do not, it is what today’s register gained or lost from the price move, marked *, and ↑shares marks a company that announced a capital raise inside the window.
Measured across 953 ASX mining and healthcare companies; 784 had a share count at this close.
