A second peer-reviewed method finds abnormal pre-attack trades across airlines and banks
- what the source states
- "Comparable abnormal trades have been found for American Airlines, United Airlines and Boeing (and to a lesser extent for Delta Air Lines and KLM) before the terrorist attacks of 9/11, and are discussed in the separate appendix."
- what we infer
- A second independent method reaching a compatible conclusion, which is why the anomaly is graded well supported rather than merely reported. Recorded with a sourcing precision this case had to correct: the granular figures widely attributed to this paper — a specific count of trades and specific dollar gains — are not in its published body but in its working-paper version and separate appendix, and are not quoted here.
- limitations
- The published paper treats the September 11 trades only summarily; its detailed findings sit in a separate appendix this case has not verified.
- Detects statistical abnormality, not identity or intent.
