No percentages here. This company's share count has moved by a factor of 2.7 over the window, from 39,954,607 to 107,225,238 shares. A split, a merger or a large issue changes what the company is, and a holding measured at one point in that run is not a fraction of it at another.

Nothing of that kind in this period.
