The report says the shorts will pay off if the S&P 500 or Euro Stoxx 50 decline and is mostly composed of puts that expire in March and are tied to around $100 billion worth of the indexes.

The trade is only a small part of the $150 billion in assets under management at the firm.

There has been a notable rise in S&P 500 put options.
