August 15 Market Report: Nvidia Retains Top Market Cap, Palantir EPS Growth Nears 20,000%

Major Stock Movements and Financial Metric Analysis

Despite broader downward pressure on the market, key companies in the artificial intelligence (AI) and semiconductor sectors maintained their positions at the top of market capitalization rankings, fluctuating within a narrow range. Nvidia, the market capitalization leader, rose 0.01% from the previous session to close at 225.3, securing a market cap of 5.46 trillion won. The table below summarizes trading data and key financial metrics for major stocks on the day.

Ticker	Price (won)	Change	Market Cap (trn won)	PER	EPS Growth
Nvidia	225.3	+0.01%	5.46	34.5	6599.3%
Apple	305.26	+0.01%	4.46	34.6	2258.6%
Alphabet (GOOGL)	346.36	+0.01%	4.24	17.4	3419.4%
Microsoft	496.88	+0.01%	3.69	27.4	3138.7%
Amazon	265.13	-0.01%	2.86	21.3	2879.9%
Tesla	339.96	+0.04%	1.34	311.9	-4709.0%
Micron	949.83	+0.04%	1.07	20.6	-
Cisco	113.47	-0.08%	0.45	34.2	3125.0%
Palantir	179.01	+0.05%	0.43	154.3	22857.1%

Data indicates that while technology stocks showed marginal movements, Palantir demonstrated relative strength by rising 0.05% on the back of an overwhelming Earnings Per Share (EPS) growth rate of 22,857.1%. Conversely, Cisco fell 0.08%, marking the steepest decline among the top 30 stocks by market cap. This is interpreted as a reflection of uncertainty in network equipment demand and conservative IT spending outlooks from corporations. Tesla recorded an EPS growth rate of -4,709.0%, sparking concerns about profitability deterioration, yet its stock rebounded 0.04% to maintain a high valuation with a P/E ratio of 311.9.

AI Semiconductor Sector Earnings Defense and Consumer Goods Slump

Despite the broader market correction, companies in the AI semiconductor supply chain defended against price declines based on robust earnings growth. While AMD showed negligible price movement, it recorded an EPS growth rate of 16,435.6%, proving its potential as a future growth driver. Nvidia and TSMC also recorded changes of 0.01% and 0.00%, respectively, outperforming market returns. ASML, a key supplier of lithography equipment essential for semiconductor fabrication, rose 0.02% to 1,847.9 won, upholding the reputation of European technology stocks.

Profitability differentiation between IT hardware and software sectors is intensifying. In particular, companies possessing AI data analysis capabilities, like Palantir, are recording explosive EPS growth, whereas traditional hardware manufacturers show relatively lower growth rates, causing investment selection to diverge.

In contrast, Amazon and Walmart, directly hit by slowing consumption indicators, showed sluggish trends, falling 0.01% and 0.00% respectively. Walmart, in particular, weakened despite a relatively high valuation within the retail sector (PER 40.7x), as theories about sales growth limits surfaced due to depressed consumer sentiment. Exxon Mobil also closed at 158.61 won, down 0.01%, following international oil price volatility and decreased energy demand forecasts. Financial stock JPMorgan Chase fell 0.01%, exploring its direction amidst expectations for rate cuts and fears of an economic slowdown.

Widening Valuation Gap and Future Investment Outlook

The most prominent feature of the current market is the extreme divergence between individual stock PERs and EPS growth rates. While Nvidia's PER has stabilized around 34.5x, Palantir (154.3x) and Tesla (311.9x) appear to have high expectations for future value already priced in. Major foreign media outlets like the Wall Street Journal analyzed that the decline in U.S. retail sales could alter the Federal Reserve's interest rate path. If consumption indicators continue to deteriorate, the possibility of a soft landing diminishes, potentially leading to further profit-taking in growth tech stocks.

Moving forward, the stock market is expected to reorganize around companies that can prove tangible profit growth with actual figures. In particular, stocks with clear profit structure improvements, such as Intel (9,865.5% EPS growth) and Cisco (3,125.0% EPS growth), are likely to have their defensive resilience tested in a downturn. While Micron's 0.04% rise positively延续了 expectations for a recovery in the memory industry, the weakness in consumer goods and energy sectors is expected to limit the upside of the broader market index. Investors should closely monitor whether actual EPS is significantly improving rather than just high PER figures, and whether macroeconomic indicators like retail sales rebound.

Overall, the market in mid-August 2026 stands at a point where technical adjustments and skepticism about economic fundamentals intersect. Inflows toward large-cap stocks with valuation appeal, such as Alphabet (PER 17.4) and JPMorgan Chase (PER 15.6), may emerge. Even while AI momentum remains valid, caution against volatility is advised for stocks forming excessively high PERs. As signs of economic slowdown become clearer, the market weight of top market cap stocks like Microsoft and Apple, which generate stable cash flows, is expected to further expand.
