13F filings with amendments or confidential positions

Declared options (25)

Besides stocks, Optiver Holding B.V declared 14 puts (they gain if the stock falls) and 11 calls (they gain if it rises) with a notional of $364 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: its portfolio is not within 5 to 100 positions; it turns over more than 50% of the portfolio per quarter; more than 20% is options; more than 20% is ETFs; it is a bank or trading desk; its positions are usually hedges or inventory. Its portfolio is shown all the same, but it is left out of manager counts, the consensus and the ranking. How this is decided

Managers of a similar size

A 13F portfolio value between a third and three times this one, whatever the type of filer. It is not a comparison of what they hold.
