True. But he is considered a savvy investor. If most people on this board can see the value in these corporations, why shouldn't he? If I remember correctly, his price at the time of his published investment was around $4 a share.
As some detractors keep repeating, we don't know if he still holds any shares, but we also don't know how much more he has accumulated. Given his investment history, I am inclined to believe he has been accumulating.
