The daily paint job EOD has been such a constant fixture in NTEK trading that it's hard to even notice any more.
I don't know if the SEC considers that a particularly heinous form of stock manipulation, but at a guess, their inaction means they don't care all that much.
And, of course, NTEK has committed far more blatant manipulation than that. The Google Super Tweet is probably the single most obvious example. Photos of empty NP-1 boxes would do it, too, but that's further in the past.
