DH has a few...but these are funds ( recognised grouping of companies) not single companies. However he followed them for at least 12 months by investing theoretically and watched their performance. He has a financial brain and does a lot of research and watches everything very carefully and on the whole it is a bit of a long game.
I think the mantra to those new to it is never invest anything you cannot afford to loose.
