Prospect Capital Corporation (NASDAQ:PSEC) sports a five-year average annual revenue growth rate of 45% and a net profit margin of 48.4%. Prospect is a private equity business development company (“BDC”), specializing in energy companies, and recently yielding close to 12%. Its earnings jumped significantly recently, and it has been busy making many new investments. A risk it faces is that of companies defaulting, but its default rate has been low and Prospect is not that leveraged, overall, compared to some peers. It has been issuing a lot of shares, though, which concerns some, but my colleague Tim Beyers has supported the move.

Seadrill Ltd (NYSE:SDRL) sports a five-year average annual revenue growth rate of about 21% and a net profit margin of 23.1%. One of the world’s largest oil and gas offshore drillers, it carries substantial debt, but also sports a massive backlog of topping $21 billion and operates in the most profitable deepwater drilling regions, among other locations. Bears don’t like its negative free cash flow , but that’s been moving in the right direction, and in the meantime, the company pays a hefty 9% dividend yield and is expanding its fleet.

Intuitive Surgical, Inc. (NASDAQ:ISRG) sports a five-year average annual revenue growth rate of 29% and a net profit margin of 30.1%. Intuitive is the leader in robotic surgical equipment, and there’s much to like about it, such as its repeating revenue from service contracts and supplies. Here’s a concern, though, that recently sent shares downward: Some studies suggest that robot-assisted surgeries may not be much more effective than traditional ones. (Some of these studies ignore the faster recovery times for less-invasive procedures.) The company has been trying to appeal more directly to doctors and hospitals lately. A new tax on medical devices will squeeze Intuitive Surgical, Inc. (NASDAQ:ISRG)’s bottom line a bit, but it has the earnings to handle it — and, on the plus side, the tax is likely to hurt its less profitable or unprofitable peers more.

Fat profit margins and heady growth are a nice combination. Just be sure to check out other numbers and factors as well before investing. Make sure you’re keeping your money in your best ideas.
