A Technical Analysis on TLG, page-925

It may well be connected to the 3B notice yesterday indicating someone had exercised 369,866 options. You would guess that exercising options so early suggests the purpose was to sell them - which may have happened today.

Incidentally, the options exercised included 69,866 listed option (45c due 31 Dec 18), and 300,000 unlisted options. The latter were made up of 50,000 unlisted 45c options (31 Dec 18) and 250,000 unlisted 54c options (20 Aug 19). The 3B from a couple of weeks ago exercised 150,000 of those same unlisted 54c option (20 Aug 19).

Tracking back the unlisted 54c options, they were issued on 20 Aug 14 as "employee options" (1.6m were issued in total). So it does appear an "employee" issued at least 400,ooo options in Aug 14 and who also was pretty strongly involved in the mid 2016 capital raising, is exiting at least from his/her options.
