I am a great believer in regular investment programmes. If you do this against a background of a long-term secular uptrend you are virtually certain to come out ahead in the end, very possibly well ahead.
My timing for starting QV for ETFs was not brilliant because shares in many centres have been performing badly. The FTSE 100 index, for example, has been trading for the three and a bit years since January 2017 at around 7,400. It is currently 6038.
