Sold out of this quarter

Valued at what the position was worth in the previous filing, because by this one it is gone.

• PDT Partners LLC · Quantitative$1.0m held before

Reported as options rather than shares

A put or a call on a name is not a position in it, and the filing states the notional rather than what the option cost. These lines are listed apart for that reason and are not counted in anything above.

What ALAB is worth

Knowing who owns it is half the question. The other half is what it is worth against the companies it trades beside, which is the one an interviewer will follow up with.

How much of the picture this is

A Form 13F reports US-listed long equity and nothing else: no shorts, no bonds, no cash and no non-US listings. It arrives forty-five days after the quarter ends, so a manager who sold in July still shows the position in a filing published in August. This page reads the managers on file here rather than every filer in the market, and each manager’s largest positions rather than the whole table, so a small position in a very large book may not appear. Say “their last filing showed” rather than “they own”, and the distinction will do you credit.
