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.

This library tags the matter as front running, insider trading and newsletter scalping, 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, Nasdaq identified in the release.
