Understanding late-day trading

Late-day trading is a deceptive practice wherein trades are executed after hours but recorded with an earlier timestamp, usually before a mutual fund’s daily NAV calculation. This manipulation allows certain investors to exploit events occurring after market hours to their advantage. For instance, a hedge fund may place trades after receiving information that impacts a fund’s value, such as significant earnings announcements.
The illegality of late-day trading stems from its violation of federal securities laws, including Section 17(a) of the Securities Act of 1933 and Section 10(b) of the Securities Exchange Act of 1934. By artificially adjusting trade timestamps, perpetrators deceive mutual funds and unfairly benefit from advantageous pricing based on outdated NAV calculations.

Late-day trading regulations

Regulatory authorities have implemented measures to combat late-day trading and protect investors’ interests. Initially, rules required broker-dealers and investment advisors to verify trade placement times. However, this system proved inadequate, leading to revisions in 2003 and 2004.
The updated regulations shifted responsibility to mutual funds to ensure compliance with trading deadlines. Purchase and redemption orders must be received before NAV calculation time, and prospectus disclosures related to market timing have been strengthened. These measures aim to prevent late-day trading and enhance transparency in mutual fund operations.

Late-day trading fines

Numerous cases have highlighted the severity of late-day trading violations and resulted in substantial fines. Notable among these is the SEC’s enforcement action against Pentagon Capital Management, a UK-based hedge fund. The fund was fined $98.6 million for engaging in late-day trades through its broker-dealer to profit from post-market information.
Courts have consistently upheld the fraudulent nature of late-day trading, emphasizing its deceitful intent and detrimental impact on investors. Despite attempts to evade liability, perpetrators have been held accountable for manipulating trade timestamps and unfairly exploiting market dynamics.
Here is a list of the benefits and the drawbacks to consider.
  • Provides investors with an opportunity to profit from events occurring after market hours.
  • Unethical practice that unfairly disadvantages other investors.
  • Violates federal securities laws and can result in substantial fines.
