That article , and it’s enclosed link, shows No Verified way to know that “ a record amount of commercial short interest exists”. The author is purely speculating this theory based on futures data. There is no mechanism I know of that compels institutions to report their short positions in real time. The numbers the author posts per category may be accurate , but there’s no granulated data for each of these categories to support his claim.
Seeking Alpha deserves to be viewed w critical skepticism, because all their “ articles” are nothing but glorified , dressed up , posts. I’ve seen “ articles “ on SA that are pump pieces for Otc scams, and I’ve seen articles that are borderline libel muck trashing a Co, because the “ author “ has a short position.
Not jumping your train here, just very critical of SA, and the author in this piece you site has no piece of evidence that directly supports the dubious premise of “ largest commercial SP short interest ever” .
