With market manipulation being so vague and up for interpretation, you might as well ban every CEO and any possible influential individual from voicing their opinion (tweeting, upvoting, chiming in) since their reputation and personas will impact the market value of the stock. People who trust in say Elon, Jeff Bezos, Trump, etc. will be likely to buy up shares of a company because these influential leaders pick sides. What is and isn't stock market manipulation is very nuance and there will be no laws that elites/hedge funds can't bypass simply with a bit of elbow grease to the lobbyist and law makers. Law makers and market markets are in the bed simply because it's almost a guaranteed successful ROI on anything they do. In the end the retail investors are stuck holding the bags.

Stop letting hedge fund managers group up together and have "idea dinners" where they plan their next strategic shorts behind closed door. Oh that's right you can't stop rich people from having dinners and talking about manipulating the market. The only thing imposing restrictions and laws in a free market now is solely to fuck over the retail investors while letting the elists continue controlling the market. I'm sure it's been thought about during the 1918 crash and the 2008 crash. Everyone is making it seem like the stock markets only experienced crippling manipulation only during 2000s. The game is set in stone and any government intervention prevents it from ever being a "free market" ideologically.
