Criminal parallel share by technique

The likelihood that a manipulation action runs alongside a criminal prosecution varies sharply by technique. Schemes with identifiable individual victims and clear documentary evidence attract criminal attention far more often than order-book conduct, where intent must be inferred from data.

The share of actions in each technique that reference a parallel criminal proceeding.

How this was calculated

A case is flagged as having a criminal parallel when the regulator’s release refers to the Department of Justice, a US Attorney, an indictment, a criminal complaint, or a guilty plea. This is a reference in the civil release, not an independent search of criminal dockets.

What this chart does not show

  • This measures what the civil release mentions. A criminal case brought later, or brought without a civil counterpart, will not appear.
  • Because DOJ coverage in this library is partial, the true criminal share is higher than shown for every technique.
  • Techniques with small samples produce unstable percentages. Sample sizes are printed on each bar for that reason.
