You wanted to buy a share, the main criteria being a gently rising dividend, yielding 7% or greater, without too much risk to your hard earned.

7% is important as it doubles your income every ten years.

First check, how reliable is the dividend ?

You check back 5 years, a lot can change in 5 years, so recent history is more important than days of yore. There has been one miss, June 2021 but a gently rising dividend.

7% is important as it doubles your income every ten years.

Mr. Market has given you a great opportunity as the yield historically was around 5%. If you had been following SUPR you could have earned a yield of 9.3%, 2% compounded over 30 years makes a huge difference. If in time interest rates fall and the yield falls as the price rises, the yield could fall back to around 5%.

Compound growth on 10k of seed capital. The really good news is that if you only have a modest amount to invest, compound interest takes a few years to make a big difference to your Snowball.

Now SUPR may not be traded in 30 years time, so you may have to switch horses but as long as your new Investment Trust or ETF, yields 7%, your yield on initial investment will be around 53%, why would you want to sell any of your shares ?

You need to check the dividend announcement 4 times a year and if the dividend is maintained or increased, you could re-invest the earned dividends back into SUPR, until the yield falls below 7%.
