How Single-Name Off-Exchange Volume Affects Options

For single-name equities, persistent off-exchange volume concentrations can flag institutional positioning - large blocks arranged through ATS venues to avoid lit-market impact, or correlation-arbitrage flow from sector rotation. The flow doesn't directly move the lit-market price (it prints at the ATS) but it changes the inventory position of the institutional counterparty, which then drives subsequent lit-market flow. Compare the off-exchange volume series above with PRA's gamma exposure and options volume history to see whether unusual dark-pool activity coincides with rebalancing in the options book.
