It gained more than a 50-percent stake of the company in January this year.

Can I replace 'gained' with 'owned' or 'bought'?
'Bought' is OK, I think, though there are other ways to acquire shares; 'owned' is not good.
Students: Are you brave enough to let our tutors analyse your pronunciation?
Note also that "bought" implies that the whole stake was bought in January. "gained" could well mean that the January purchase was a smaller one that tipped an existing stake over 50%.
Thanks, Mr M and Mr W.
