Consider a deep discount oil Closed End Fund such as Adams Natural Resources which currently trades at a 15% discount to net asset value. PEO is about 16% XOM and 10% CVX. Holdings include about 35 oil stocks plus some service firms. Very blue chip and strongly US oriented. PEO dates back before 1929.
PEO has a 6% managed payout so it works well for those wanting a higher payout (which can sometimes cut into principle). I like CEFs as conservative investments but only if they trade 15% or more below NAV.
PEO has held SDRL at times (not sure about now). Also a Dow Index fund will get you some XOM and CVX. I've owned CEFs and index funds for many decades.
