Sonia Attkiss is Facing a Billion-Dollar Investor Dispute Involving YES

Sonia Attkiss (CRD #: 2936806), a broker registered with UBS Financial Services, is involved in an investor dispute regarding her recommendations of YES (Yield Enhancement Strategy). This is according to her BrokerCheck record, accessed on April 20, 2022.

On December 21, 2021, investors alleged that Sonia Attkiss recommended an unsuitable options overlay strategy called YES. This strategy involved selling call and put options and lost money in a volatile market. Brokers should have known about these risks and warned their investors before investing. The investors are seeking to recover $1,200,000,000; the dispute is pending.

There are seven pending investor disputes alleging Sonia Attkiss misrepresented an unsuitable options overlay strategy. Earlier disputes are collectively seeking over $11 million.


  • FINRA Rule 2111 prohibits investors from recommending unsuitable investments. Brokers must only recommend investing strategies that fit their customer’s risk tolerance.
  • FINRA Rule 2020 prohibits misrepresentation. Brokers are not allowed to provide investors with unrealistic projections for future growth. They also should accurately represent the risk for losses.
