"Mr. Rowghani has been selling Twitter shares heavily since May, when insiders were first allowed to sell after the company’s initial public offering in November.
Last month, he sold 300,000 shares, worth about $10 million. And this month, he sold nearly 75,000 shares worth more than $2.5 million. He remains a major stockholder, however, owning about two million shares, according to his latest regulatory filing."
This is a non-story. This is a guy that had a mountain of net-worth 'on paper' and since he is now legally able to, he's brought a portion of that net-worth into the bank.
I don't know about you, but if I had 50MM+ on paper in a single investment, I'd want to take at least a fifth of it and turn it into cash for investing elsewhere, building that dream home, going on vacation, etc.
Now, maybe he's filthy rich already, but this just strikes me as a very typical, sane 'diversify your assets' type of situation.
