The following video is part of our "Motley Fool Conversations" series, in which analyst John Reeves and advisor David Meier discuss topics across the investing world.

Over the past six months, lots of great growth companies have seen their share prices fall pretty dramatically. John and David think there are two great growth stocks out there that are very much worth buying today. The first one is InvenSense, which makes motion sensors for electronic devices, including smartphones using Google’s Android operating system. The company believes the previous issues at Qualcomm are behind it, putting InvenSense squarely back on the growth track.

The other stock is MAKO Surgical. The company has hit a slow patch, which is never good for a growth company. But its installed base of orthopedic surgical robots should help influence the next round of purchases. It may not be the next Intuitive Surgical, but it’s got a great shot. As with any growth stock, it’s important to take a long-term view. There will be ups and downs. But if the business has a good product and a big market to serve, the odds of success go up. That’s why John and David own both of these companies in their real-money portfolio.

The recent market sell-off of MAKO Surgical shares has some folks wondering whether the potential growth prospects of the robotic surgery company make it a buy today or a stock to be wary of. Read our premium report to catch up on the details of MAKO's story. Click here to access it now.
