关于此图
- Size = issuance (shares offered × par) — the face value of the deal. A filed share count backs 318 of 378 issues; the rest show at a floored size and faded. Switch Size → Liquidity (average daily dollar volume, ~99% covered) or Equal to weight every issue the same.
- Colour is the day's move by default; Current yield diverges around the median (high-yield green, low red) and vs Par is discount-green / premium-red. Grey means the issue didn't trade on the latest session, so its move can't be shown.
- Sectors are normalised from the raw
issuers.sectorfield into 10 groups. Yields exclude anything flagged as suspect, matching the rest of the site.
