40,000% gain in one day

There is a lot of talk about the 'timing' of the SEC charge against Goldman Sachs as it related to hearings on regulations, but did anyone notice that the timing fell on an options expiration day? Goldman Sachs April $165 puts jumped from 1 cent to $4, a 40,000% gain! Bhahaha! I hope GS was not in on this short for a change! What is the SEC's motivation: fixing the wrong or crowd control?
