The study of Form 4s, which track changes to stock holdings by company directors and officers, showed an average timing advantage of about 10 seconds.
On Tuesday, filings were published on the SEC’s website an average of 35 seconds after Mr. Jackson received them on his direct feed. The lag dropped to 27 seconds on Wednesday, when the Journal article was published. On Thursday and Friday the delay narrowed even more, with filings appearing on the SEC’s “Edgar” site an average of about three seconds and 2.5 seconds, respectively, after being published on Mr. Jackson’s feed. The drop in the lag time continued Monday, according to Mr. Mitts.
