There are a multitude of reasons why JPM would be buying wamuq... but the two obvious reasons would be to:
a) payout in wamuq shares and pretty much screw us over even more
b) to limit the amount of outstanding shares that they will have to make payouts to.
However, if JPM, or subsidiaries were found to be buying up wamuq shares wouldn't that lead to another lawsuit or more problems? Idk if JPM is that dumb, but based on their track record, its very probable that they are eating up these shares.
