"Owning the right penny stock can really turbocharge a portfolio’s performance. For evidence, look no further than Filtronic, which was trading for 7p per share just over five years ago. Today, you’d have to pay more than 220p for the very same share!
The flip side, of course, is that penny stocks are notoriously high-risk. For every Filtronic, there are many dozens that completely bomb. Therefore, while exciting, I would only ever invest a very small part of my portfolio in an ultra-small-cap stock. But that might be all that’s needed.
Returning to Filtronic, for example, £150 invested in this stock five-and-a-half years ago would now be worth nearly £5,000!" End
