What this tells us
2 of today’s 2 actions reference a parallel criminal proceeding, which is a high share for a single day. The 2 techniques represented today span part of the taxonomy. A single day tells you very little on its own — enforcement counts are dominated by the timing of announcements rather than by anything happening in markets. The year index and the charts are where a trend would show up, if there were one.
