Guides to gilts and to using GiltIQ, written against the site's own data and pages.
A conventional gilt's gross yield is a cash return and an index-linked gilt's real yield is a return after the inflation the gilt is priced for, so the two are only comparable once the inflation between them is put back explicitly.
An index-linked gilt's clean price can be quoted with the inflation uplift inside it or with the uplift taken out, and the two figures differ by the index ratio — which is why the basis matters as much as the number.
The DMO yield follows the gilt market's twice-yearly, actual-days convention while the annual figure compounds once, and the two differ by an amount that grows with the level of the yield.
The net redemption yield is the gross yield with income tax on the coupons taken out, so the gap between the two columns depends on the coupon and the price rather than on the gilt's quality.
A gilt is quoted per £100 of nominal on a clean basis, and the pounds paid at settlement are that quote plus the accrued interest, multiplied by the nominal bought.
A gilt row can carry two price changes, one for the clean price and one for the dirty price, and they differ because the accrued interest moves every day and resets on each coupon date.
The trend column draws a gilt's recent yield history as a sparkline, and the twelve-month record behind it is the context that turns a single day's change into a meaningful move.
The Change column on a gilt row records how far the yield moved between two stored reports, and reading it correctly means knowing which two reports and what a blank cell means.
A gilt row carries a change in its yield and a change in its clean price, and the two always point in opposite directions because they measure one movement from two sides.
A guide to every column on the conventional gilts list, what figure each one shows and where that figure comes from.
A gilt is quoted per £100 of nominal value, so the pounds it actually costs are the dirty price multiplied by the number of £100 units bought.
A reference to the three yields GiltIQ shows for a gilt — gross, DMO and net redemption — and the rules for comparing them without mixing conventions.
