I’m not the smartest person out there, but I don’t see why not.
Greg, Ted, Todd, and Ajit are all capable, ethical people I trust to run the company. Berkshire is nice because even ignoring the wholly owned stuff, half of the stuff they own you can feel good about holding for decades. Plus you have the potential dividend if the new managers recognize they aren’t Warren and instead focus on maximizing investor returns via stuff like that instead of stock picking.
Is Berkshire really that different from a curated SP500 type index even without Buffett?
