What is alleged to have happened

the Securities and Exchange Commission announced this matter on December 10, 2018 as release 34-84764. The respondents named are Lai Guanglin (Alan) (1 individual, 0 entities).

This library tags the matter as marking the close and price manipulation, based on the conduct the regulator describes. Each tag links to a page explaining how that technique works, what statute it engages, and what penalties comparable actions have attracted. The tagging is ours, not the regulator's: agencies charge statutory provisions, not technique names.

The conduct is recorded against equities, with NYSE identified in the release.

The relief recorded in our data is a civil monetary penalty of $400,000. Penalty and disgorgement are distinct: disgorgement returns the gain, while the penalty is punitive. We store them separately so that aggregate figures across the library are not double-counted.

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.
