Market Behavior

Market Behavior is a data page on the Markets desk of Glassbox Auditing. Trading patterns such as pressure into the close, moves toward a strike on expiry day and activity before announcements, flagged for review in stored trades and quotes, beside a library of documented enforcement and court matters, each with its legal status. These are the patterns market surveillance looks for, and the cases show how regulators and courts have treated them.

What does this page lead to?

Federal Reports (Calendar): One template measures trading in the hour before scheduled releases such as the Fed decision and the jobs and CPI reports, and the move in the hour after, so each date on Federal Reports is an anchor it checks. (either way, depending on the cause; the hour around each release; economy scale) Source: Market behavior measured by the terminal (fixed episode templates over stored trades, quotes and bars).
Company Reports (Calendar): The same template anchors on companies' results filings (8-K item 2.02), measuring trading in the hour before the filing time; whether the news was public earlier is not checked. (either way, depending on the cause; the hour before each filing; company scale) Source: SEC EDGAR filings (10-Q/10-K text).
Dealer Gamma (Options): On monthly and quarterly expiry days a strike holding a large share of the expiring contracts can draw the price toward it as hedges unwind; Dealer Gamma shows where such strikes sit. (either way, depending on the cause; expiry day; economy scale) Source: Market behavior measured by the terminal (fixed episode templates over stored trades, quotes and bars).
Courts & Lawsuits (Companies): The case library lists enforcement and court matters for the same trading patterns, each with its legal status; a matter naming a listed company also appears among its cases, as an allegation until ruled on. (either way, depending on the cause; as filed; company scale) Source: SEC litigation releases.
Stock by Stock (Markets): Two templates compare SPY with its holdings: a few large holdings moving the index, or SPY's price drifting from its basket until arbitrage closes the gap; Stock by Stock shows those holdings' own days. (either way, depending on the cause; same day; company scale) Source: State Street, SPY daily holdings.
Retail vs Institutions (Markets): One template flags a shift of a stock's volume between venues beside a price move; the same venue mix, on and off exchange, is what Retail vs Institutions reads from FINRA's weekly files. (either way, depending on the cause; same day; sector scale) Source: FINRA OTC Transparency weekly summary (dark pool and other off-exchange shares per stock and firm).
Fear Gauge (VIX) (Briefing): Order books thin out when volatility is high, so short bursts against a thinning book, one of the patterns here, tend to be more common on days the VIX is elevated. (moves the same way; same day; economy scale) Source: Cboe VIX index data (daily history and delayed quotes).

Stock by Stock (Markets): The engine checks each stock's stored trades and bars for the same days Stock by Stock shows, against that stock's own usual session, and flags the patterns it finds for review.
