If you’re like me, you’re an eternal optimist when it comes to the march of scientific progress and its ability to improve human life. Making new technologies, foods, and medicines is never easy, but it still pays off time and time again for investors and members of the public alike. If you want to get rich off of advancements in science, however, you’ll need to know which innovative companies are the most promising — preferably long before everyone else realizes the same thing.
The stocks that I’ll discuss today are micro-cap stocks, which means that they have market capitalizations between $50 million and $300 million. Think of them as early stage public companies that don’t have much consistent revenue yet. Their products or methods might be unproven, but their businesses tend to have a lot of room to grow. So, while you shouldn’t allocate 100% of your portfolio to micro-cap stocks, they can be great for long-term investing.
