Try something ethical. Might not offer returns in line with tobacco companies, but seriously – are you all happy propping that industry up?
I don’t care. The whole concept of investment is doing whatever to make more money flow from others to me.
Tobacco etc. historically have reasonably good returns, and even when UK/EU/US might be swaying towards e-fags, the rest of the world can’t get enough baccy.
There are ethical fund trackers etc. too.
As for diversification, 100% agree. Hence monthly few quid in a tracker. It evens out the peaks and troughs, so if the market goes down, your 20 quid buys a little more, and when it goes up, it buys a little less. And the costs of a computer that picks stocks once every quarter when the make-up of the FTSE 250/100 is adjusted, are minimal.
Utilities is the other single stock or single sector I’d look at. Water, Leccy, Gas etc. also tend to be recession-proof and pay big dividends (probably find a lot of pension funds investing there). Some will call that unethical too. Investing in what others believe should be state owned.
Whatever, make sure it’s wrapped up via ISA.
