🔥 HOT: NCS Multistage Holdings (NASDAQ: NCSM) has been flying high since its fourth-quarter earnings report revealed an EPS nearly triple consensus estimates. The stock has gained 42.4% since its earnings call on March 10th, with daily volumes 2-3 times higher than its pre-earnings average. We give NCSM B ratings in Momentum, Growth, and Financials and an overall Zen Rating of A. The company has surpassed its profit targets for the last four quarters and is on track for an outstanding 2025.

🥶 NOT: Shares of Luminar Technologies (NASDAQ: LAZR) continued coming back to Earth on Wednesday as the stock lost 12.0%, closing in the red for the third straight day. The company showed some life after its latest earnings report, but even outperforming Wall Street’s predictions for EPS and revenue couldn’t erase the bad taste investors have from a year-over-year loss of 78.4%. There’s not a lot we like about LAZR. It gets F ratings for Value, Financials, and Momentum and C ratings in Growth, Sentiment, and Safety. It’s one saving grace that prevents it from being an F overall is its partnership with Volvo and Nvidia. We give LAZR a D Zen Rating and a Sell recommendation.

🔥 HOT: Perimeter Solutions (NYSE: PRM), a chemical company that makes firefighting foam, gained 10.0% on Wednesday after analysts at UBS raised the stock from neutral to buy. The increase in frequency and intensity of wildfires means that PRM’s products are going to be in higher demand than previously expected as long as weather conditions continue to trend hotter and drier. Our internal research gives PRM an A rating in Sentiment and a B rating in growth, leading to an overall Zen Rating of B and a Buy recommendation.

🥶 NOT: AirJoule Technologies (NASDAQ: AIRJ) lost 26.6% on Wednesday after an upbeat call with shareholders that revealed improvements in the company’s bottom line and efficiency breakthroughs for its primary product line. So why did it lose so much? Unfortunately, our analysis shows that despite outward appearances, AIRJ isn’t the most stable company. We give AIRJ D ratings for Value, Safety, and Financials, which means that it’s a risky play that’s more likely to go sour on you than generate significant returns. While it does get a B rating for Sentiment, the cold, hard truth is that the company is on uneasy footing at best. We give AIRJ a D Zen Rating and a Sell recommendation.
