I’m saying the author of the article (the reddit post) approached valuing it based on fundamentals. That is the whole point of a short equity squeeze - a stock’s valuation is predicted by many (wrong folks) to fall, institutional money takes a large short position, but a few smart speculators see a valuation-based reason why the price will actually (truly, not artificially) go up, thus squeezing the short sellers. The strategy kicks in only at that point, when buying and holding (based on speculating more intelligently about the true valuation) leads to further gains because of the short sellers’ situation. The reddit author even says explicitly - this is not a pump and dump, the stock will stay high.
Sharing a smart analysis and offering others the chance to execute the same strategy is not manipulation. It’s just a smart strategy. This guy and others who saw the opportunity early, realized GME was both fundamentally undervalued and also had super high short interest, just out-smarted professional traders and they are mad, so resorting to backchannel politics to drum up claims of “manipulation.”
