IMO. What can effect the SP is extremely subjective. If you have read an article and formed an opinion, yes, it has the potential to effect the SP. If you read about another debt financing company, it has the opportunity to effect the SP.
I wouldn't say that those majority holders and large buyers are going to be persuaded too much by an article, but it may spark their interest into understanding the fundamentals and trajectory of the business.
I personally wouldn't put my money into the shallow opinions of MF authors, when their main outputs are purely click bait and "Where to put your next 1k" titles articles. They're target audience is small scale investors and hence SP shouldn't be effecting in the long.
