Up to three companies side by side: how their shares have moved, then how the businesses compare on their latest filings and year by year.
The largest companies we cover in the same industry — tap one to add or remove it. No price move is shown beside a name: it would have to be measured over one window while the chart uses another. 5 more competitors with Pro
Every line starts at 0% at the left edge of the window, so what is compared is how each price moved — not what a share of any of them costs.
The latest figures from each company’s own filings, side by side. On measures of the business — growth, margins, returns and the balance sheet — the strongest and weakest of the companies shown are marked. Price and size are left unmarked: a lower P/E is a fact about the price, not about the business.

Each company’s last six fiscal years, as the amount or as the change on the year before.
Each fiscal year is placed in the calendar year most of its months fell in — NVIDIA’s year to January 2026 sits beside AMD’s year to December 2025 — so bars in one column cover close to the same twelve months. Hover a year to see each company’s own year end. Amounts are in US dollars. TTM is the latest twelve months each company has reported, so it runs past its last fiscal year. As a % change it is measured against the twelve months a year earlier.
