% of holdings sold = shares sold ÷ (shares sold + all holdings the insider reported on that Form 4, direct and through trusts).
Insider type follows Cohen, Malloy & Pomorski (Journal of Finance, 2012). An insider who traded the stock in the same calendar month in each of the past three years is a routine trader; one who traded in each of those years without such a pattern is an opportunistic trader. In their study, trades by opportunistic insiders predicted future returns and trades by routine insiders did not. Counts open-market purchases and sales only (SEC Form 4 codes P and S) by that insider in that company. Not investment advice.

- “Based on information available as of today, Ambarella is offering the following guidance for the third quarter of fiscal year 2027, ending October 31, 2026: Revenue is expected to be between $115.0 million and $124.0 million. Gross margin on a non-GAAP basis is expected to be between 59.0% and 60.0%. Non-GAAP operating expenses are expected to be between $56.5 million and $59.5 million.”
