When Markets close on Friday nearly every market participant from brokers, analysts, investors, money managers and even the media flee their terminals and turn their attention to their personal lives until they boot up again on Monday morning. Monday is when everyone logs back on gets plugged back into the market pulse and are bombarded with the latest news of the morning.

Experienced management from public companies that are very crafty and slick who wish to hide SEC disclosure file any unfavorable news on Friday Nights when everyone is away knowing that when the new week starts, last week's news is buried. Michelle Leder of @Footnoted coined Friday Night Filings as the #FridayNightDump

Journal of Accounting and Economics published research by professors from Cornell University and Simon Fraser University unveiling statistics of Friday Night Filers.

"Abstract

Using combinations of weekdays and times of day (before, during, and after trading hours) of earnings announcements, we examine whether managers attempt to strategically time these announcements. We document that the worst earnings news is announced on Friday evening and find robust evidence that only Friday evening announcements represent managers’ rational opportunistic behavior. Friday evening announcements are followed by insider trading in the direction of earnings news and the largest post-earnings announcement drift. Managers also attempt to reduce interaction with investors and hide more than just earnings news by announcing on Friday evening. We find that Friday evening announcements occur later in the evening than announcements on other evenings, firms have a reduced propensity to hold conference calls, and major firm restructuring events are relatively more likely to occur after Friday evening announcements."

Michelle Leder of *Footnoted is one of the best follows on all

of Twitter. Every Friday night she posts about public

companies who sneak in SEC filings before the

weekend,.... sometimes to simply avoid being noticed.
