Declared options (25)

Besides stocks, Mirae Asset Securities (usa) declared 25 puts (they gain if the stock falls) with a notional of $1.3 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.

Stakes above 5% (13D/13G)

Companies where this filer reported holding 5% or more of the shares. It is the figure from its latest filing on each one; history since December 2024.

How we classify it

Not counted as a concentrated manager: 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.
