Declared options (6)
Besides stocks, SummitTX Capital declared 4 puts (they gain if the stock falls) and 2 calls (they gain if it rises) with a notional of $94.7M. 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
Type not verified: we have not assigned a type because we found no document that is enough to tell. Most 13F filers are in this situation: we only review in depth those that meet the portfolio criteria.
Not counted as a concentrated manager: it has fewer than 8 quarters of history; its portfolio is not within 5 to 100 positions; its top 10 positions are under 45%; more than 20% is ETFs. 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.
