How to read it

2013–2026 · strongest month on average Nov +3.6% · weakest Sep -1.1%

Every value plotted for a past date could have been computed on that date. Normalised series expand their window rather than scaling against the full history, so nothing here is drawn using information that did not exist yet — which is also why the early years of a normalised series are dropped rather than shown against a range of one.
