> Short sellers taking positions and then putting out report and marketing to bring a company’s price down can also be perceived as market manipulation.

Sure, in the same sense that releasing a 10-K can be perceived as market manipulation. In fact, if we define "market manipulation" to mean anything that might affect the market, many things can be perceived as market manipulation!

The question I think is more important is, is it bad? Sharing investment information you believe to be true and material to investors seems good to me.
