Dark Pool Activity: CLH — 35,457,890 shares traded off-exchange
This report covers off-exchange dark pool trading activity for $CLH on FINRA-registered Alternative Trading Systems (ATS). Dark pool volume data is published by FINRA on a two-week delayed basis under its ATS transparency program. Institutional investors favor dark pools to execute large block trades while minimizing the market impact that would result from routing the same orders through public exchanges. A spike in $CLH dark pool activity — particularly when it represents an elevated percentage of total market volume — often precedes significant price moves, as institutional accumulation or distribution can take multiple sessions to complete.
