Recently a number of folks here and on other websites have mentioned some utility ‘illiquids’ for a possible purchase for those wanting a very safe income stream.
The very old (issued in the 1950’s and 1960’s) preferred shares from Connecticut Light and Power (parent Eversource-ES) are now selling at attractive levels providing current yields of 6.3% to 6.9%. These issues are all $50 issues and trading volumes are pretty lite. They may be redeemed at anytime at various redemption prices – $50 or above. They are cumulative and qualified.
I have a spreadsheet of $50 and $100 issues here – I do not keep this well updated but it is a starting point for potential investments.
