Markets are supposed to be random, the SUPR chart above says otherwise.

You would like to add SUPR to your Snowball, or you may already own and earned part of the 39% rise since a year ago.

The current yield is 7.1%

You have two choices, you can buy on or after the xd date when the share will most probably have fallen by the dividend 1.54p. You get more shares for your money and in the long run you should earn more dividends.

If you buy before the xd date, you will receive the dividend and in just over one year, you should receive 5 dividends around 7.7p.

A yield of 9%, if interest rates continue to fall, the share in the past traded above its NAV and may do again.

You could take your profit and try to do it all over again or just continue to hold subject to the current yield.
