Declared options (2)
Besides stocks, 140 Summer Partners declared 1 put (they gain if the stock falls) and 1 call (they gain if it rises) with a notional of $166M. The 13F reports the value of the underlying shares, not the premium paid, so these figures look large and are not added to the portfolio. Nor does it say whether the option is bought or written, or its strike or expiry: it may be a hedge.
