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 NSP's gamma exposure and options volume history to see whether unusual dark-pool activity coincides with rebalancing in the options book.

Frequently asked NSP market structure questions
- What is the current NSP off-exchange volume?
- For the week ending May 25, 2026, Insperity, Inc. (NSP) recorded 574.0K shares across 3.0K trades (average trade size 192 shares). The 12-week cumulative total is 9.7M shares.
- What does NSP off-exchange volume mean for traders?
- Off-exchange volume on a single-name equity reflects institutional block trades arranged through alternative trading systems (ATS) for liquidity rather than information reasons. Persistent ATS volume on a name can signal large institutional repositioning; the lit-market price impact lags the off-exchange print by hours to days as the institutional counterparty hedges or unwinds.
- How is NSP market-structure data sourced?
- Weekly off-exchange volume figures come from FINRA's OTC Transparency reporting, which captures trades executed through FINRA-member off-exchange venues including ATSs and member firm internalization desks. FINRA publishes the data with a two-week lag (current-week-minus-two-weeks) for ATS-specific volume and weekly aggregate volume; the totals here aggregate all member firm reporting. Trades cleared via the listed-exchange auction are NOT included; the figure reflects only the off-exchange portion of total volume.
