There's a precedent where the SEC thought otherwise. In the case, the defendants later agreed to a settlement and admitted wrongdoing. The following text is from the link, emphasis mine:

Describing the
illegal short squeeze, Gerald W. Hodgkins, Associate Director of the SEC’s Division of Enforcement said, “After he took control of an entire issue of high-yield bonds, Falcone
kept buying with an eye toward rigging the market and punishing short sellers to settle a score. In the process, Falcone hijacked the market for the bonds and illegally manipulated their price and availability. The Division will continue to police the bond market to make sure it operates as an efficient market, free of the corrosive effects of manipulators such as Falcone.”
