July 21 Market Report: Nvidia Falls 0.02% as Global Big Tech Closes Defensively

Global Market Consolidation and Big Tech Defense

On July 20, 2026, major global stock markets exhibited a weak consolidation trend, driven by heightened geopolitical tensions between the U.S. and Iran and investor caution ahead of earnings reports from major technology firms. The domestic market also saw a continued defensive stance, characterized by shrinking trading volumes due to recent volatility in large-cap semiconductor stocks and controversy surrounding leveraged ETFs. In this market climate, share prices of major global companies recorded only marginal fluctuations, testing strong support levels. An analysis of market capitalization leaders reveals that most firms showed volatility within the 0% range.

Symbol	Price	Change	Market Cap	PER	EPS Growth
Nvidia	$202.81	-0.02%	$4.91T	31.1	6599.3%
Apple	$333.74	+0.00%	$4.90T	40.5	2258.6%
Alphabet	$346.77	-0.02%	$4.23T	26.5	3419.4%
Microsoft	$393.82	-0.02%	$2.93T	23.5	1551.4%
Tesla	$380.84	-0.03%	$1.43T	346.2	-4709.0%
Applied Materials	$529.66	-0.06%	$0.42T	49.7	-
Micron	$848.95	-0.00%	$0.96T	19.2	-

As shown in the table, Nvidia ranked first with a market cap of $4.91 trillion, closing at $202.81, down 0.02%. Apple also maintained its market cap of $4.90 trillion, ending the session effectively flat at +0.00%. Applied Materials was among the stocks with the steepest decline in this session, finishing down 0.06% at $529.66. Micron showed a near-flat decline of 0.00%. Despite the burden of geopolitical risks, large-cap companies are holding firm without significant selling pressure.

Sector Divergence via Profit Growth and Valuation

While stock price movements were muted, indicators of corporate profit growth and valuation showed stark contrasts. Nvidia, the biggest beneficiary of AI semiconductor demand, recorded an explosive EPS growth rate of 6599.3%. Despite such extreme profit growth, Nvidia's P/E ratio remains at 31.1. This suggests that while future earnings are already largely reflected in the stock price, the pace of operating profit growth sufficiently supports it. Alphabet also recorded a profit growth rate of 3419.4% with a low P/E of 26.5, indicating it remains in an undervalued range.

In contrast, indicators for eco-friendly automaker Tesla reflect market concerns. Tesla closed at $380.84, down 0.03%. A larger issue is the deterioration in corporate profitability. Tesla's EPS growth rate plummeted to -4709.0%. Consequently, Tesla's P/E ratio soared to 346.2x, indicating earnings are dismally low relative to the share price. This numerical deterioration for Tesla is interpreted as a cold market assessment due to slowing global EV demand and delays in new businesses.

Rise of Defensive Stocks and Market Outlook

As volatility in growth stocks increases, capital rotation is moving towards traditional value stocks and essential consumer goods. Consistent capital inflows have been detected in the healthcare and essential consumer goods sectors. Eli Lilly traded at $1,179.11, up 0.01% from the previous session, recording a market cap of $1.05 trillion. Johnson & Johnson also rose 0.01%, absorbing defensive investment demand. Major retailers like Walmart and Costco also recorded slight gains within the consolidation range. This can be interpreted as institutions and individual investors rebalancing their portfolios towards stocks with earnings stability amid growing market uncertainty.

Given the remaining military tensions in the Middle East and political variables in major nations, global markets are expected to struggle to find clear direction. In particular, the second-quarter earnings results of Big Tech firms like Alphabet and Microsoft, announced in earnest this week, will be key variables deciding the market's course. If the explosive profit growth of the AI semiconductor sector, represented by Nvidia and Micron, continues, the market may gain the momentum to break through the current consolidation and turn the index upward. However, stocks like Tesla, which face high valuation burdens and delayed earnings improvement, will find it difficult to avoid further adjustment pressure. Investors need an approach that strictly manages the mix of defensive assets and core growth stocks, considering the clear polarization in performance between sectors.
