I'm sure you meant to say, "when Barron's carried a small news note about a shill who claimed ALGN was a $3 stock."
I like Barron's because they are somewhat ruthlessly devoted to the actual facts a lot of the time. They have the humility and self respect to admit early and often that they might be wrong and describe the reasons that support the idea they are in error.
They report those shill comments every week. Some of them contradict each other on the same page.
