September 15 Market Report: Cisco Led the Gains
Cisco Rises Most at +0.04%... Big Tech Catching Its Breath in Flat Territory
Cisco posted the largest gain among the stocks surveyed, up +0.04%. Intel (+0.03%) and AMD (+0.02%) followed, while most other large-cap tech stocks hovered within roughly ±0.02%, essentially flat. The data, compiled as of September 14, 2026, shows that the major U.S. technology stocks were effectively standing still.
This stagnation is not unrelated to the uneasy market mood from the previous trading session. According to Yonhap News, the three major New York indexes all closed lower, weighed down by a plunge in semiconductor stocks amid calls for a slowdown in AI development, as well as rising Treasury yields and oil prices, with the Nasdaq falling 0.56%. SK Hynix's U.S.-traded ADRs dropped 7.6%, a steeper decline than fellow memory maker Micron. The individual quotes presented today can be read as the starting line in the process of recovering losses from that sharp drop.
| Stock | Price | Change | Market Cap | P/E |
|---|---|---|---|---|
| Cisco | 112.13 | +0.04% | $0.44T | 33.7 |
| Intel | 102.94 | +0.03% | $0.54T | - |
| AMD | 516.13 | +0.02% | $0.84T | 131.7 |
| Apple | 332.27 | +0.02% | $4.85T | 38.1 |
| Alphabet (GOOGL) | 338.50 | +0.02% | $4.14T | 17.0 |
| Amazon | 256.78 | +0.02% | $2.77T | 20.7 |
| Nvidia | 218.29 | -0.00% | $5.27T | 27.6 |
| Micron | 975.26 | -0.00% | $1.10T | 22.0 |
| Oracle | 150.28 | -0.02% | $0.43T | 23.5 |
Network and Semiconductor Names Led the Gains
The rankings reveal a clear pattern. Cisco (+0.04%) rose from 107.44 to 112.13 versus the prior day, recording the largest increase among the stocks surveyed. Intel (+0.03%), whose earnings base is so weak that no P/E ratio is available, rebounded from 100.32 to 102.94. Oracle, by contrast, was the only stock with a clearly negative move at -0.02%, while Nvidia and Micron were essentially pinned at their previous closing prices.
Nvidia remains at the top of the market-cap rankings at $5.27 trillion, followed by Apple at $4.85 trillion and Alphabet at $4.14 trillion. Nvidia's P/E ratio of 27.6 is lower than Apple's (38.1). Given that its quarterly EPS growth rate reaches 6,599%, its strong earnings growth has so far offset valuation concerns. Alphabet, with a P/E of 17.0, is the cheapest among big tech, a level often cited as grounds for a relative-undervaluation thesis.
The Weight of Stocks with P/E Ratios Above 100
Tesla's P/E ratio stands at a staggering 332.2. Palantir (142.9) and AMD (131.7) are also in triple digits. However, the picture changes when EPS growth is factored in. Palantir posted EPS growth of 22,857% and AMD 16,435%, showing that their elevated P/E ratios rest on surging profits. Tesla is the problem: its EPS growth was recorded at -4,709%, placing it in the same camp as companies with shrinking earnings such as Meta (-256%) and Chevron (-3,186%).
High-valuation stocks with declining earnings face particular pressure during periods of rising interest rates. The previous session's rise in Treasury yields, which dragged down the indexes, reads as a clear warning signal. Meanwhile, a Yonhap report that Bank of America's chief executive warned of a sharp drop in fee income, pressuring bank stocks, underscores again the earnings-visibility problem facing financials.
What Flat Trading Means, and Investment Implications
A flat market is not a direction — it's a pause for breath. With news on AI regulation and safety raising the possibility of greater short-term volatility in semiconductor stocks, the market is unlikely to commit to a firm direction until more fundamental signals emerge, such as cutbacks in AI investment or slowing memory demand. Indeed, in the data presented, Micron maintains a relatively low valuation among chip stocks, with a market cap of $1.10 trillion and a P/E of 22.0.
For investors, two points stand out. First, EPS growth and the P/E ratio should always be examined together. Even among high-P/E stocks, Palantir and AMD — backed by growth — carry a different risk profile than Tesla, which is not. Second, assets with low P/E ratios and stable portfolio characteristics, such as Alphabet (17.0), Berkshire Hathaway (12.8), and JPMorgan (15.3), could serve as defensive plays in periods of heightened volatility. In a market where watching costs nothing, today's flat session is buying time to determine the next move.
