We are short shares of Virgin Galactic Holdings, Inc., often described as the only publicly traded space-tourism company. After going public in October 2019 by way of a merger with a “blank check” company, Virgin Galactic has seen its share price and trading volume soar. It’s become a retail darling, with day traders captivated…

We are short shares of Plug Power, a $40 billion provider of hydrogen fuel-cell solutions that’s set to generate a paltry $300 million in revenue in 2020 and trades at 40x its own aggressive revenue projection for 2024. The company’s stock has almost doubled in just the last few weeks, and has risen by 15x in the last year…

We are short shares of Fubo, a $6bn company that has seen its share price increase 4x following its October 7^th IPO on the NYSE. Remarkably, even after its recent retracement from truly nosebleed levels, Fubo still trades at valuations completely unmoored from reality: 14x 2021E sales, equivalent to $12,000 per current…

We are short shares of Tattooed Chef, a $1.2bn packaged-food company that trades at about 7.5x 2020 revenues despite extreme customer concentration and flagging retail sales. Having recently gone public through acquisition by Forum Merger II Corporation, a special purpose acquisition company (SPAC)…

We are short shares of AtriCure, a $1.9bn medical device company that manufactures and sells ablation equipment used in the surgical treatment of atrial fibrillation (AF). At about 7x forward revenues, AtriCure’s valuation implies that the company’s outlook is brighter than at any point in the last decade. But with…

We are short shares of Mirati Therapeutics, a $4.6bn clinical-stage biopharmaceutical company whose lead drug candidate, MRTX-849, is a small-molecule KRAS inhibitor (KRASi). The KRAS protein plays a critical role in cell proliferation and differentiation, and mutations of the gene that encode it are present in…

We are short shares of Match Group and IAC/InterActiveCorp, two companies trying to break apart before an FTC lawsuit that alleges a disturbing level of civil fraud and a parallel DOJ criminal investigation leads to the market dumping them both. Last September, the FTC sued…

We are short shares of Principia Biopharma, a company whose $2 billion valuation rests on a single obscure molecule known as Bruton’s tyrosine kinase (BTK). Named after a pediatrician who discovered an immunodeficiency later found to be caused by a defective mutant form of…

We are short shares of CareDx, a $1.7bn diagnostics company whose share price has increased by 30x over just the last two years and now trades at over 18x sales. The meteoric rise and generous valuation have come in the wake of excitement over the commercialization of AlloSure, a blood test intended to identify organ rejection in kidney transplant recipients. Transplant nephrologists have long used measures of kidney function to assess the probability of rejection, with a tissue biopsy providing a definitive diagnosis. To hear CareDx tell it, AlloSure is the…

Tucows (TCX) operates two declining tech/telecom businesses and a fledgling low-return fiber division, yet is being valued by the market at 60x trailing normalized earnings. Its two profitable segments barely deserve double-digit earnings multiples given their bleak growth profiles, and the company’s cash flow is being plowed back into a third segment that will prove to be a massive destroyer of capital. TCX’s valuation is wildly overstretched and the stock is worth 50%+ less…

We are short shares of Qualcomm Incorporated, a semiconductor company teetering on the brink of disaster. For years, Qualcomm has presented itself as a technological innovator that monetizes its R&D in two ways: 1) selling chips that go into smartphones and other wireless devices and 2) licensing its patent portfolio. The licensing business, despite contributing far less revenue than the chip business, has historically supplied roughly two thirds of Qualcomm’s…
