No percentages here. This company's share count has moved by a factor of 20.0 over the window, from 1,919,441 to 38,339,697 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.
