In the firm's Q1 letter to investors, David Einhorn's Greenlight Capital disclosed new long positions taken during the quarter, including taking stakes in HP Inc. (HPQ), Penn Entertainment (PENN) and Roivant Sciences (ROIV). In the letter, the firm stated that it established a new "medium-sized position" in Penn at an average price of $22.69 per share, arguing that "were the market to credit PENN with merely 15% of DraftKings' value, [Penn's ESPN BET] segment alone would be worth $20 per share." On HP Inc., Greenlight stated that it had established an initial position at an average price of $30.76 per share, adding that it believes "that we are, at a minimum, on the cusp of a normal PC refresh cycle, which should drive earnings above estimates." On Roivant, Greenlight said it had established a "small long position," adding that "in addition to an exciting pipeline, ROIV has a strong track record of positive trial results and successful monetization of pharmaceutical assets." Einhorn's Greenlight Capital also noted that it reduced its Teck Resources (TECK) long position into strength during Q1 and that the firm bought a "small position" in Liberty Global (LBTYA) during Q1.

The firm, which included the "important reminder" that "this is just a petition," says the uncertainty created by the petition is "incrementally positive" for First Solar and negative for Canadian Solar (CSIQ), Array Technologies (ARRY) and Nextracker (NXT).

Ferrari (RACE) announces that Ferrari S.p.A. has signed a multiyear partnership agreement with HP Inc. (HPQ), through which its brand will appear on racing properties of Scuderia Ferrari.

As previously reported, Evercore ISI analyst Sean Morgan upgraded First Solar to Outperform from In Line with an unchanged price target of $227. The market is expecting the Biden administration to remove a trade exemption for bifacial solar modules imported to the U.S., which now represent about 98% of U.S. solar imports, the analyst noted. Solar panel imports skyrocketed in 2023 to 54GW and some market participants have stated that reliance on imports and oversupply are negatively impacting solar domestic factories, which have been a priority for the current U.S. administration, putting pressure on greater U.S. trade protections and policy support, the analyst added.
