Can I use this fact to detect upcoming potential investigations or enforcement actions which may not be public knowledge, and use that to my advantage?
[Edit:] This also seems to have the unfair effect that SEC employees get an "out" from previous investments in companies that the SEC is about to investigate. Isn't that ultimately another form of trading on insider knowledge, even if it's mandatory?
On the other hand, if SEC employees are not forced to sell, then their holdings may diminish their impartiality. It seems like the only fair and neutral approach is to require SEC employees to hold no individual stocks at all during their employment - or any type of financial instrument issued by organizations they might potentially investigate.
(Is this perhaps what the SEC means, that employees are forced to sell because they've just joined the SEC? If they're forced to sell an individual instrument only at the beginning of a specific investigation into a single organization who issued the instrument, then that seems like a loophole.)
