Intel Upgraded, CVS Health Downgraded: Updated Rankings on Top Blue-Chip Stocks

Market analyst Louis Navellier, editor of Growth Investor, released an extensive update to his proprietary Stock Grader system on September 14, 2026, revising the ratings for 93 prominent blue-chip companies. The adjustments, which range from significant upgrades to "Very Strong" buys to downgrades into "Very Weak" sell territory, reflect a shifting landscape in institutional buying pressure and corporate fundamental health. Among the most notable moves in this rebalancing are the elevation of semiconductor giant Intel Corporation (INTC) to a top-tier rating and the downgrade of healthcare conglomerate CVS Health Corporation (CVS) to a "Strong" but diminished status.

The revisions come at a critical juncture for the equities market as investors navigate the final weeks of the third quarter. Navellier’s methodology focuses on two primary pillars: quantitative grades, which measure institutional buying pressure or "big money" flow, and fundamental grades, which assess a company’s financial health, including earnings growth, profit margins, and cash flow. Of the 93 stocks reviewed, 14 were upgraded to the highest rating of "Very Strong," while others faced downgrades that suggest a cooling of investor enthusiasm or deteriorating balance sheets.

Leading the Upgrades: The Rise of Intel and Industrial Leaders

The upgrade of Intel Corporation from a "Strong" to a "Very Strong" rating (Total Grade: A) serves as a centerpiece of this week’s report. Despite a "C" fundamental grade, Intel’s "A" quantitative grade suggests that institutional investors are aggressively accumulating shares. This trend likely reflects optimism surrounding the company’s long-term foundry services strategy and its efforts to reclaim leadership in the semiconductor manufacturing space.

Joining Intel in the "Very Strong" category are several companies tethered to global infrastructure and commodities. Bunge Global SA (BG), a leader in agribusiness and food ingredients, received an "A" total grade, driven by high institutional demand. Similarly, Nucor Corporation (NUE), the largest steel producer in the United States, was upgraded to "Very Strong," reflecting its robust "B" fundamental grade and "A" quantitative score. These upgrades suggest a rotation toward "old economy" stocks that provide essential materials and services.

Other notable upgrades to the "A" level include:

• Travelers Companies, Inc. (TRV): The insurance giant shows balanced strength with a "B" in fundamentals and an "A" in quantitative pressure.
• nVent Electric plc (NVT): As a provider of electrical connection and protection solutions, nVent is benefiting from the ongoing electrification of the global economy.
• Venture Global, Inc. Class A (VG): The energy infrastructure firm continues to see high marks for its role in the liquefied natural gas (LNG) export market.

Healthcare and Consumer Staples: A Mixed Performance

The healthcare sector saw significant volatility in this round of ratings. While Viatris, Inc. (VTRS) and Illumina, Inc. (ILMN) were upgraded to "Very Strong," several industry stalwarts faced downgrades. CVS Health Corporation (CVS) was moved from "Very Strong" to "Strong" (Total Grade: B). While a "B" rating still indicates a healthy outlook, the downgrade suggests that the intense institutional buying pressure seen earlier in the year may be tapering off.

Amgen Inc. (AMGN) also saw a downgrade from "Very Strong" to "Strong." This shift highlights the competitive pressures within the biotechnology sector, where drug pricing regulations and patent cliffs remain constant concerns for analysts. Conversely, Pfizer Inc. (PFE) saw an upgrade from "Neutral" to "Strong," suggesting that the pharmaceutical giant may have found a floor after a prolonged period of post-pandemic adjustment.

In the retail and consumer discretionary space, Five Below, Inc. (FIVE) moved up to a "Very Strong" rating. The discount retailer’s ability to maintain high fundamental health ("B") while attracting institutional capital ("A") underscores the resilience of the value-oriented consumer segment. This stands in stark contrast to Dollar Tree, Inc. (DLTR), which was downgraded from "Strong" to "Neutral" (Total Grade: C), indicating a loss of momentum relative to its peers.

Semiconductor and Technology Shifts

The semiconductor industry remains a focal point of Navellier’s Stock Grader. Beyond Intel, several other tech firms saw upward revisions. Analog Devices, Inc. (ADI) and Arista Networks Inc (ANET) were both upgraded from "Neutral" to "Strong." Arista, in particular, continues to benefit from the expansion of data center infrastructure required for artificial intelligence applications.

On Semiconductor Corporation (ON) and Monolithic Power Systems, Inc. (MPWR) also received upgrades to "Strong" status. These companies are integral to the automotive and industrial power management sectors, which are seeing increased demand as vehicle electrification and factory automation accelerate.

However, the report was not universally positive for the tech sector. Qualcomm Incorporated (QCOM) and Skyworks Solutions, Inc. (SWKS) only managed upgrades from "Weak" to "Neutral." While this represents an improvement, their "C" and "D" fundamental grades, respectively, indicate that these companies are still struggling with soft demand in the smartphone market and other consumer electronics.

Downgrades to Neutral and Below: Areas of Caution

A significant portion of the 93-stock list involved downgrades to "Neutral" or "Weak" status, signaling areas where investors might consider trimming positions. High-profile names like UnitedHealth Group Incorporated (UNH) and Southern Company (SO) were downgraded to "Neutral." For UnitedHealth, a "B" fundamental grade remains a point of strength, but a "C" quantitative grade suggests that institutional support is currently stagnant.

The "Weak" and "Very Weak" categories saw several surprising entries:

• Lululemon Athletica Inc. (LULU): Despite its brand dominance, the athleisure leader was upgraded only to "Weak" (Total Grade: D), hampered by an "F" quantitative grade. This implies that large-scale investors are currently exiting the stock.
• General Mills, Inc. (GIS): The packaged food giant was downgraded to "Very Weak" (Total Grade: F). A combination of an "F" quantitative grade and a "D" fundamental grade suggests significant headwinds in the consumer staples sector, likely due to rising input costs and shifting consumer preferences.
• AutoZone, Inc. (AZO): The automotive parts retailer fell to "Very Weak," reflecting a sharp decline in institutional buying pressure.

Analysis of Institutional Buying Pressure

The core of the Stock Grader’s quantitative assessment is the "Quantitative Grade," which acts as a proxy for institutional interest. In Navellier’s system, an "A" quantitative grade is often considered the most important metric, as it indicates that pension funds, mutual funds, and hedge funds are actively buying the stock.

In the current list, 14 stocks hold an "A" quantitative grade alongside an "A" total grade, including Bunge Global, Intel, and Nokia. When a company like Intel maintains a "C" fundamental grade but earns an "A" quantitative grade, it suggests that the market is "forward-looking," pricing in a recovery or a strategic shift that has not yet fully appeared on the balance sheet.

Conversely, companies like UnitedHealth Group or Dollar Tree, which possess "B" fundamental grades but "C" quantitative grades, are in a "wait-and-see" period. Their business models remain sound, but the lack of institutional buying pressure suggests that the stock price may remain range-bound or underperform the broader market in the near term.

Chronology of Market Adjustments

The September 14 update follows a period of heightened market volatility characterized by fluctuating interest rate expectations and geopolitical tensions. Over the previous quarter, the Stock Grader system has increasingly favored companies with high free cash flow and those positioned to benefit from domestic infrastructure spending.

The transition of stocks like Rivian Automotive, Inc. (RIVN) from "Weak" to "Neutral" marks a slow stabilization in the electric vehicle sector, which had been battered by high interest rates and cooling demand earlier in 2026. Meanwhile, the consistent downgrades in the utilities sector—such as Ameren Corporation (AEE) and Alliant Energy Corporation (LNT) moving to "Neutral"—suggest that the defensive "yield play" of utilities is losing its luster as investors seek growth in other areas.

Broader Economic Impact and Implications

The 93 rating changes provided by Louis Navellier offer a microcosm of the broader U.S. economy in late 2026. The strength in industrial and steel stocks (Nucor, nVent) points toward a robust cycle of domestic manufacturing and infrastructure renewal. The upgrades in the semiconductor space (Intel, Arista, Analog Devices) reinforce the narrative that the "digital backbone" of the economy is still a primary driver of capital allocation.

However, the "Very Weak" ratings for consumer staples like General Mills and retailers like AutoZone suggest that the "cost-of-living" pressures may finally be eroding the fundamentals of traditionally stable sectors. For portfolio managers and individual investors, these ratings serve as a warning that "blue-chip" status does not equate to immunity from market shifts.

As the market enters the final quarter of the year, the focus will likely remain on whether the companies upgraded to "Very Strong" can translate institutional interest into fundamental earnings beats. For downgraded stocks like CVS and Amgen, the challenge will be to regain the "A" quantitative grade by proving to institutional players that their current valuations represent a long-term opportunity rather than a value trap.

Navellier concludes that staying on top of these data-driven shifts is essential for maintaining a growth-oriented portfolio. The Stock Grader tool remains a proprietary resource for his subscribers to navigate these frequent rebalancings, ensuring that their holdings align with the current flow of institutional capital.
