Declared options (25)
Besides stocks, Alkeon Capital Management declared 5 puts (they gain if the stock falls) and 20 calls (they gain if it rises) with a notional of $48.1 bn. 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.

How we classify it
Not counted as a concentrated manager: more than 20% is options. Its portfolio is shown all the same, but it is left out of manager counts, the consensus and the ranking. How this is decided
Similar managers by type and size
Same type of filer and a 13F portfolio value between a third and three times this one. It is not a comparison of what they hold.
