Because there weren't any HESG FTDs. The SEC says no FTDs means no report on HESG. See italicized details below.
I have a question that addresses my original post, what is the significance of posting the daily regsho? It doesn't show HESG short interest nor open positions at the end of each day. It's only about ownership marking.
If the aggregate net balance of shares that failed to be delivered is zero as of a particular settlement date on or after September 16, 2008, then no record will be present in the file for that date. Fails to deliver on a given day are a cumulative number of all fails outstanding until that day, plus new fails that occur that day, less fails that settle that day. The figure is not a daily amount of fails, but a combined figure that includes both new fails on the reporting day as well as existing fails. In other words, these numbers reflect aggregate fails as of a specific point in time, and may have little or no relationship to yesterday's aggregate fails. Thus, it is important to note that the age of fails cannot be determined by looking at these numbers. In addition, the underlying source(s) of the fails-to-deliver shares is not necessarily the same as the underlying source(s) of the fails-to-deliver shares reported the day prior or the day after.
