Okay, if that's the case, then say "investing in sustainable companies" rather than "divesting from fossil fuel companies" because doing the latter does not imply that you are also doing the former.

And by the same logic I mentioned, you'd still have to be buying the stock from the company itself, not from someone else, to ensure that you're actually helping them. If a company isn't selling their stock, it's not at all clear that buying their stock from someone else helps the company.
