Why This Trade Stands Out
Strong conviction signal
Scored above average across multiple factors. Roughly 15% of insider trades qualify as Strong.
~$9.3M purchase
Trades over $1M are rare. When insiders put this much of their own money on the line, they tend to have high conviction in their company's direction.
CHIEF FINANCIAL OFFICER
CFOs have direct access to financials before they become public. Their trades are among the most closely watched by institutional investors.
3 insiders traded in the same window
When multiple insiders independently buy within 30 days, it's called a cluster. Studies show clustered insider purchases outperform solo trades significantly, because several people with inside knowledge are reaching the same conclusion.
-8.7% in 90 days (S&P 500: -2.5%)
This trade underperformed the S&P 500 by 6.2 percentage points. Not every insider trade wins. We track all of them so you can focus on the insiders with the best records.

See who else bought · FreeOn September 12, 2022, Mick Gary — CHIEF FINANCIAL OFFICER of Six Flags Entertainment Corporation — filed a Form 4 with the SEC disclosing an open-market purchase of approximately ~$9.3M in Six Flags Entertainment Corporation (SIX) stock.
This transaction was part of a cluster — 3 insiders at Six Flags Entertainment Corporation made open-market purchases within the same 30-day window. Cluster activity from multiple independent insiders is one of the most studied patterns in insider trading research.
Under Section 16(a) of the Securities Exchange Act of 1934, corporate insiders must report all open-market stock transactions to the SEC within two business days.

How to Read Insider Trades
What is this?
When company executives buy or sell their own stock, they must report it to the SEC within 2 days. These public filings reveal what the people who know the company best are doing with their own money.
Why does it matter?
Insiders can sell for many reasons (taxes, diversification, expenses), but they generally only buy for one: they think the stock is going up. That's why insider purchases are more predictive than sales.
What makes a trade "strong"?
We score trades on 15+ factors: the insider's role (CEO > director), trade size relative to their salary, whether other insiders also bought (clusters), and historical accuracy of the insider.
