Stock Market Outlook for August 2025: Identifying Investment Opportunities

Key Insights on the Stock Market Outlook for August 2025

• The market valuation outpaced growth rates, primarily driven by just five companies.
• There’s still a hefty premium on growth stocks.
• Small-cap stocks, while appealing, might need some time to gain momentum.

As of July 31, 2025, the US stock market was aligning with fair value estimates. With a July increase of 2.3%, the overall valuation dropped slightly, mirroring what was seen at the end of June. This shift indicates that our fair value measures grew significantly compared to the overarching market capitalization. Overall, we increased the fair value of 143 companies while decreasing it for 36 others.

Interestingly, although the number of declining stocks grew, only five companies marked a rise in capitalization priority. Take NVIDIA, for example: its fair value surged over 20% after the US resumed the sale of H2O AI GPUs to China. NVIDIA’s market cap stands at $4.3 trillion, reflecting a whopping $900 billion increase—almost equivalent to Tesla’s, which is ranked 10th in terms of market cap.

Similarly, Microsoft saw its fair value rise by nearly 20%. With a market cap of $4 trillion, this increase translated to about $800 billion, paralleling companies like JPMorgan Chase and Walmart, which occupy the 11th and 12th spots in market capitalization. Meta Platforms also appreciated by 10%, adding around $200 billion to its market cap, much like Caterpillar. Both Taiwan Semiconductor and JPMorgan benefited from an elevation of roughly $170 billion each in fair ratings.

In total, these five firms account for an impressive $2.2 trillion in market capitalization. For some perspective, that’s comparable to 22 other companies each valued at $100 billion. Currently, there are roughly 140 companies with market caps exceeding that benchmark.

Trading at Fair Value Means No Cushion Against Macro Risks

The market’s current premiums fail to provide a buffer for investors against various looming risks. Notably, ongoing trade and tariff negotiations pose significant short-term uncertainties, especially with some of the largest trading partners like China, Canada, and Mexico still unresolved. Moreover, US economic growth has experienced a continuous slowdown, and economist Preston Caldwell from Morningstar isn’t predicting recovery until early 2026. But the sluggish trend isn’t confined to the US; Europe’s growth is also dampening, influenced by slumping numbers from China and Japan.

Looking at other potential risks, inflation metrics haven’t yet captured the tariff-induced inflation spikes, but Caldwell anticipates that tariffs could inflate numbers by the latter half of 2025. Additionally, long-term interest rates have been languishing near low trading points since last October, with the Fed likely to stay on hold for a couple of months while inflation heads upward.

Valuations are Boosting Growth Stocks, Yet They’re Still Overvalued

The Morningstar US Growth Index outperformed the broader market, enjoying a 2.95% rise in July. However, our price-to-fair value measures dipped slightly from an 18% premium at the end of June to a 16% premium by the end of July, primarily due to the substantial growth in firms like NVIDIA, Microsoft, and Meta.

From a sector standpoint, we still recommend overweight positions in the value category, as it is trading at a 7% discount to its fair value. To balance this, we advise reducing exposure in the growth category, which is trading at a 16% premium. Historically, growth stocks don’t typically trade at such elevated premiums. Despite that, there are still attractive undervalued options in the growth domain, like Marvell and Workday. Individual undervalued stocks might serve investors better than a broad-focused ETF.

Value stocks currently rate better on both absolute and relative valuation benchmarks. Following several fair value increases for individual stocks last month, core stocks have emerged as appealing options.

The Morningstar US Small Cap Index experienced a 2.1% uptick in July, closely trailing the broader market. On both absolute and relative bases, small caps remain notably attractive, trading at a 16% discount to fair value estimates. Given that large stocks are at a 1% premium, investors might find a compelling case to overweight small caps.

Identifying Value Across Sectors

This revenue season has been largely focused on artificial intelligence. The most significant fair value increases were found in the Information Technology and Communications sectors, closely linked to AI hardware manufacturing, cloud platform hosting, and AI-enhanced services. However, other sectors like Financial Services have also witnessed considerable valuation increases, particularly among large US banks, which, thanks to their solid positions, deters defaults while lending continues to ebb.

The health sector, contrastingly, has faced major downgrades in fair values, particularly for large pharmaceutical and healthcare insurance firms. AI’s disruption has also led to depreciated inventory values in various companies, notably impacting industries such as advertising. Additionally, several economically sensitive sectors, including airlines and basic materials, have also seen value reductions.

Healthcare

The healthcare sector now appears significantly undervalued, especially as telecom stocks rise. Recent government policy changes, rising healthcare costs, and disappointing revenue forecasts—especially for Medicare Advantage products—have weighed heavily on valuations. The Morningstar US Healthcare Index, as of late July, saw a 3.87% decline, marking it as one of the two sectors with negative returns this year.
