No. As a general rule of thumb the super wealthy do not handle their own cash and investments. They have highly paid financial advisors that do that for them. And for the most part, barring a few exceptions, they invest in high value well established businesses. Not in new up and coming... err or down and going companies. You have to think a lot of actors/ actresses are one divorce, one bad incident, one awful film away from not having that big pipeline of cash. So, in general, their money is usually handled with extreme care. Again, not in all cases, but in most.
