The shape of the figures

Each spoke is one ratio. Further out means a higher figure than more of the index — not a better one. A high P/E or high debt sits far out too, so the size of the shape is not a score.

Drag to turn the shape. Tap or point at a dot to read the figure behind it.

The figures and what each one means are below. A hollow dot means the company doesn't report that figure.

Key figures, against the S&P 500

Figures as of 9 Nov 2026, refreshed weekly

Each bar places this company among the S&P 500 companies that report that figure. Further right means a higher figure — not a better one. Whether higher or lower suits you depends on what you are looking for, so the bars don't add up to a score.
