Top 5 Buy Calls:

1. Chipotle upgraded to Buy at Rothschild & Co Redburn

Rothschild & Co Redburn upgraded Chipotle (CMG) to Buy from Neutral with a $55 price target. The firm says the correction in the shares reflects cyclical softness in Chipotle’s growth rather than structural weakness in its growth model. The company’s near-term expectations have been resent, but its unit economics remain best-in-class, supported by a “defensible value proposition, productivity innovation, and significant white-space expansion,” Rothschild tells investors in a research note. The firm believes Chipotle’s risk/reward now skews positive.

2. Zscaler upgraded to Overweight at Morgan Stanley

Morgan Stanley upgraded Zscaler (ZS) to Overweight from Equal Weight with a price target of $320, up from $280. The company has a strong position in zero-trust along with a longer-term platformization strategy, the firm tells investors in a research note. Morgan Stanley believes the Red Canary acquisition enhances Zscaler’s AI security capabilities. Morgan Stanley sees valuation upside for the shares.

3. Hubbell upgraded to Overweight at Wells Fargo

Wells Fargo analyst Joseph O’Dea upgraded Hubbell (HUBB) to Overweight from Equal Weight with a price target of $490, up from $445. The firm sees the company’s organic growth at 10% over the next four quarters, following negative 3% growth in the past four quarters. This should drive Hubbell’s relative valuation higher, the analyst tells investors in a research note. Wells expects positive revisions to consensus estimates.

4. Argus upgrades Wynn Resorts to Buy on Macau recovery, Vegas leadership

Argus upgraded Wynn Resorts (WYNN) to Buy from Hold with a $145 price target. The firm is positive on the company’s prospects for share gains and its leadership position in the Las Vegas market. Argus further cites “significant recovery” in Macau and anticipates “rapid growth” at the Wynn Al Mar Jan in UAE, boosting its FY26 EPS view by $1.20 to $6.50, the analyst tells investors in a research note.

5. Verisk Analytics initiated with an Outperform at Wolfe Research

Wolfe Research initiated coverage of Verisk Analytics (VRSK) with an Outperform rating and $320 price target, which offers 21% upside. The firm says the company’s strong structural position, recurring revenue growth profile, industry-leading margins, and growth opportunities from areas such as extreme events and property estimating warrant a premium valuation relative to peers.

Top 5 Sell Calls:

1. Dollar Tree downgraded to Reduce at Gordon Haskett

Gordon Haskett downgraded Dollar Tree (DLTR) to Reduce from Hold with a $95 price target. Following the Q2 earnings report, the firm remains concerned with Dollar Tree’s move into higher price points. The company’s traffic decelerated sequentially by 240 basis points, the firm tells investors in a research note. Gordon Haskett believes the downstream ramifications of Dollar Tree’s price changes to the business model “are immense.”

2. BNP Paribas Exane downgrades Constellation to Underperform after guidance cut

BNP Paribas Exane downgraded Constellation Brands (STZ) to Underperform from Neutral with a price target of $123, down from $181, following the company’s FY26 guidance cut. The firm’s “increasingly bearish thesis” is based on persisting, structurally skewed demand issues. BNP sees long-term beer operating margins as the “next shoe to drop” as volume pressures continue. The firm adds that its FY27 and FY28 EPS estimates are 16% and 23% below consensus, respectively.

3. Lam Research assumed with an Underweight at Morgan Stanley

Morgan Stanley analyst Shane Brett downgraded Lam Research (LRCX) to Underweight from Equal Weight with a price target of $92, down from $94, as the analyst took over coverage of the stock. Lam has regained market share led by NAND, China, and share gains at TSMC (TSM), but the firm is not confident about NAND and China growth into 2026, the analyst tells investors.

4. Fortinet downgraded to Underweight at Morgan Stanley

Morgan Stanley analyst Meta Marshall downgraded Fortinet (FTNT) to Underweight from Equal Weight with a price target of $67, down from $78. The firm believes the company’s consensus estimates for out year growth need to come down, likely pressuring the stock. Disappointment in Fortinet’s core firewall refresh will overwhelm the investment story in the near term, the analyst tells investors in a research note. Morgan Stanley believes the maturity of the company’s firewall refresh opportunity is not appropriately reflected in 2026 and 2027 Street estimates, providing a headwind to the shares.

5. Paramount Skydance initiated with an Underperform at BofA

BofA initiated coverage of Paramount Skydance (PSKY) with an Underperform rating and $11 price target. While the firm believes Paramount Skydance has the potential to be a dynamic global media company, it adds “there are no easy fixes and a turnaround such as this will take a significant amount of time,” pointing to Warner Bros. Discovery (WBD) as evidence that the restructuring will likely take years to implement, require substantial investment and investor patience.
