What a joke, short it then. We're waiting
@Rajadurai：Why a crash in meme stocks AMC and GameStop.. The substantial stock sales by directors of GameStop GME, +0.28% and AMC Entertainment Holdings AMC, +10.06% didn’t surprise most rational investors. It’s clear that the current prices of these and other meme stocks are vastly inflated. In fact, investors should have seen AMC’s issuing new shares at its bloated price to raise capital as a warning sign. Critics might lambaste the opportunism of such insider selling, citing corporate governance gurus encouraging director ownership to align interests with public shareholders. But who can blame them? What is surprising is that more outside shareholders haven’t taken the signal to sell. It’s common for savvy investors to scan insider purchases and sales for signs of good or bad news ahead. Aggregate insider trading levels presage total stock returns for up to two years, according to the research of University of Michigan finance professor Nejat Seyhun, author of Investment Intelligence from Insider Trading. That said, some insider trades contain no signal at all, as directors buy when required to maintain mandatory ownership levels and sell when they need cash or to diversify investments. Moreover, insiders face reputational and legal risks when trading, so are careful not to signal hoarding good or bad news, lest they veer into unethical or illegal insider trading. But these meme-stock cases seem clearer. At AMC, for instance, many directors all sold around the same time in large numbers, near the company’s recent stock offering. Research by Durham University accounting professor Guanming He and colleagues indicates that the presence of concentrated insider stock-selling is associated with an increase in stock-price crash risk. That stands to reason: insiders know more than outsiders, whether investors, strategists or economists. Of course, no one can discern the fickle features of markets that precipitate reversals. But He’s research supports the view that insiders’ anticipation of future stock-price crash risk — from whatever source — does lead them to trim their holdings. In particular, the evidence is that insider sales are associated with 15-month-ahead crash risk. Such research may be particularly meaningful in the bizarre context of meme stocks. Compared to conventional stock trading, insiders are poised to make greater profits trading meme stocks and their trades are more informative given the greater degree of noise trading by uninformed traders. Research on past outcomes is no guarantee of future results, but together with common sense and an appreciation that all bubbles eventually burst, I’d be willing to place my own bets. The 15-month time frame would put the bursting of the GameStop bubble in the first quarter of 2022 and AMC around the third quarter. I’d certainly take both bets before I bought either stock.
