If you was a decent starting investment that pays an extremely reliable dividend I’d give my vote to City of London Investment Trust (CTY on London Stock Exchange.)
An investment trust works in a similar way to a fund (ETF or mutual) there are some differences but I wouldn’t worry about those finder details as they are more technical and don’t impact the investment.
These guys are not on the cheap side in terms of ongoing fees, they are active managers and being listed on London Stock Exchange isn’t cheap. I like to think you get value for money though.
This was the first big dividend paying stock I ever picked up, they are heavily UK focused but spread across multiple industries. They are very well known for never reducing their dividend.
Personally I don’t hold this investment anymore as I go for accumulation units or don’t value a dividend as much.
