Reference Case Number: FOI9983
Freedom of Information: Right to know request:
1. The number of alerts relating to insider dealing and market manipulation, (but not suspected market abuse) generated as a result of FCA internal surveillance.
2. How many instances of suspected market abuse were reported to the FCA over the same period?
3. How many enforcement investigations relate to insider dealing and market manipulation?
a. How many are ongoing?
b. How many were closed without further action?
c. How many relate to activity detected at firms dealing in contracts for difference?
FCA response:
By way of context, however, please note that alerts and STORs are intelligence tools, not tools for measuring market abuse. It is not possible to draw useful inferences between the raw number of alerts, STORs and enforcement cases and we would caution against using trends in these data to make assumptions about the amount of market abuse in the UK or our work.
We work with firms who submit STORS and with our own internal alerts systems to optimise their utility as lead generators for potential market abuse. However, we do not pursue fixed conversion rates. Alerts, and to a lesser extent STORs, are susceptible to external variables, such as market volatility. Alerts are particularly sensitive to experiments we run around calibration, and we are comfortable with various levels of false positives between alerts and between different time periods. We deploy advanced analytics techniques and tools both before and after alert generation to assist with the triage of cases. STOR numbers are sensitive to supervisory work we conduct with firms, with STORs typically rising or falling following our supervisory work. The relationship between STORs and alerts and enforcement cases is not linear. A case may be generated from a single alert or may map to dozens of STORs and alerts.
