In August 2024 the Securities and Exchange Commission announced a final judgment against Shaohua (Michael) Yin, a Hong Kong private equity partner charged with trading DreamWorks Animation and Lattice Semiconductor shares through five nominee accounts, for alleged profits of $29 million on DreamWorks and about $7 million on Lattice. The judgment imposes a $39.5 million penalty paid from frozen funds and an injunction; his alleged Lattice source, Benjamin Bin Chow, was separately enjoined, barred and convicted.

A dash means the release did not state a figure we could extract, not that the figure is zero. Penalty and disgorgement are stored separately so aggregates across the library do not double-count the same dollars.

What is alleged to have happened

The Securities and Exchange Commission announced this judgment on August 30, 2024 as release LR-26093, in a Southern District of New York case begun in 2017. The final judgment was entered on August 16, 2024 and concludes the SEC's litigation.

The amended complaint alleged that Yin amassed more than $56 million of DreamWorks stock ahead of Comcast's April 2016 acquisition and over $44 million of Lattice stock ahead of its November 2016 sale. Chow's judgment was entered in August 2022 and a broker-dealer and adviser bar followed in September 2022.

For the regulator's own account of the facts, read the primary document linked above. This page deliberately summarises the structured record rather than reproducing the release.

Money note: the dollar amounts in this record's text describe the $39.5 million penalty in the August 2024 final judgment; to avoid counting the same amounts twice, the money fields are left empty here and the figures are held on the record for the same case under release LR-23747 (sec-shaohua-michael-yin-et-al-insider-trading-2017).

Same matter

The library links these 2 records because they appear to concern one matter: the same lead defendant, an overlapping technique tag and close filing dates, or a shared court docket or a release that cites the other. Records are listed by date filed.

This grouping is the library's, made by matching names, techniques, dates and citations when the site is built. It is not the regulator's or a court's determination that the records are one case, and it errs towards missing a link rather than making a false one.
