Yep "including clients of our wealth management businesses."
The people running the UBS wealth management business need to be terminated. This is most likely the catalyst for why UBS is actually suing. Rest of the "clients" who did no research and just bought into the hype are just along in the lawsuit for the ride.

unlikely. from their quarterly report " NASDAQ ultimately filled all of these orders, exposing UBS to far more shares than our clients had ordered".
their clients ordered X shares of FB. UBS sent out 5 * X shares (or something like that). they sent out extra orders because NASDAQ wasn't sending acknowledgements for the initial orders. so UBS had to liquidate 4 * X shares at a loss, because the price took a dive. the loss from liquidation is why they sued.
