The invention relates to the technical field of fund
transaction data processing, in particular to a security investment fund
transaction data processing method and
system, and the method comprises the following steps: capturing external original information, and completely storing the external original information in an undetermined information
pool without content screening; identifying fund transaction; analyzing statistical characteristics of fund outflow behaviors; judging whether the fund transaction is in a collaborative low-speed outflow state or not; if it is judged that the state is the collaborative slow outflow state, first-level early warning is generated; when the total fund
outflow rate of the fund exceeds a first preset threshold value in a preset first time window, extracting corresponding fund outflow information, and querying whether first-level early warning exists or not; if yes, the fund outflow information and the first-level early warning are combined to form an event
record, and the potential external inducement information is attached to the event
record to form a composite abnormal event report. Cooperative low-speed fund outflow caused by hidden external information can be effectively identified and early warned.
