🔥 HOT: Shares of DexCom (NASDAQ: DXCM) rose by 9.7% on Tuesday after the U.S. Secretary of Health, Robert F. Kennedy, Jr., announced an advertising campaign aimed at bringing more awareness to wearable health devices. DexCom makes a wearable glucose monitoring system to help people with diabetes manage their condition and stands to gain from increased awareness in the space. Our research finds that DXCM is Financially (B rating) strong and has significant Growth potential (B rating). We give the stock an overall Zen Rating of B and a Buy recommendation.

🥶 NOT: Circle Internet Group (NYSE: CRCL) is a newly IPO-ed stock that controls the crucial USDC stablecoin that allows cryptocurrency users to easily convert U.S. dollars to other tokens. The company gained more than 300% in just over two weeks since its IPO before losing 25% on Tuesday in a move that suggests that its previous rally was largely due to short-term traders. Our analysis of CRCL puts it in the middle of the pack compared to other stocks in the credit services industry. Its current Value is its weak point, and the D rating we give it reflects our opinion that this initial run-up is powered by hype more than fundamentals. We give CRCL a C Zen Rating and a Hold recommendation, for now.

🔥 HOT: Uber’s (NYSE: UBER) stock popped for a 7.5% gain on Tuesday after the company began offering autonomous ride-hailing services via Waymo’s robotaxis in Atlanta, Georgia. This news comes on top of Uber’s aggressive expansion of EV chargers for its drivers in major cities like London and Boston as it attempts to be the first ride service to fully adopt self-driving and electric vehicles into its services. Uber’s strong suits are its Financials and Sentiment, both of which receive A ratings from our analysis. The company’s Growth potential and current Value leave a little to be desired, which lowers its Zen Rating to B. Still, that’s enough to put UBER on your radar and for us to give it a B rating.

🥶 NOT: Shares of language-learning app developer Duolingo (NASDAQ: DUOL) lost another 5.7% on Tuesday, bringing its total drop to 21.8% since its recent swing high 11 trading days ago. The company is in a strong place Financially (B rating) but has been facing backlash over its decision to become an AI-first company by firing a large portion of its translators and cultural advisors. The backlash triggered a selloff and prompted the company to scrub its TikTok and Instagram accounts in an attempt to mitigate the negative discourse about the decision. The company’s fundamentals are still strong, but that might not matter if the public sentiment surrounding the company remains this negative. We give DUOL a C Zen Rating and a Hold recommendation.
