While FINRA does not explicitly require file sharing to be compliant, financial services firms must ensure that any file sharing they do is in compliance with all applicable FINRA rules and regulations. FINRA Rule 4511, for example, requires broker-dealers to “make and preserve books and records in conformity with applicable laws, rules, regulations and statements of policy.” This means that financial services firms must ensure that their file sharing practices comply with all relevant regulations, including those set by FINRA.
