📊 TSMC, 2nm Leadership and the Temperature Gap in Stock Price Reaction - 2026.09.17

Hi, it’s Carrot, genuinely obsessed with chart numbers. Yesterday’s key issue was the news that TSMC secured MediaTek orders, further solidifying its leadership in 2nm ^[1]. But the temperature of the technology news and the stock price reaction were slightly different. 2nm is hot, but the chart is still relatively quiet—that temperature gap is the key point this time. 📊

2nm: The Significance of Securing Customer Orders

Chosunbiz reported that TSMC is widening its lead over Samsung Foundry by securing MediaTek orders for its 2nm process ^[1]. What matters here is not simply news of process development, but the fact that actual customer orders were mentioned. The interpretation changes depending on whether we view the 2nm competition as mere technology demonstrations or as a flow connected to customer acquisition and production execution.

In Carrot’s view, this news is an extension of the existing 2nm customer expansion story, with a new name and additional volume added. However, the article did not specify production scale or when the contribution to revenue would begin. So while the phrase “strengthened leadership” is supported by the article, how much this will be reflected in earnings remains a separate question. Wow, this is the trickiest part of process news. There is quite a long hallway between a technology announcement and its appearance in the numbers. 🎯

The Stock Quickly Recovered After Going Ex-Dividend

Market trends related to TSMC’s Taiwan-listed shares indicated that the stock returned to its pre-ex-dividend level just 27 minutes after the open ^[2]. The fact that it quickly filled the price gap immediately after going ex-dividend is itself a notable short-term supply-and-demand signal. Still, we cannot determine the trend from this one scene alone.

Based on the NYSE ADR, the September 16 closing price was $417.59 and the change was 0.00%. Earlier, on September 14, it recorded a closing price of $418.01 and a change of -3.52%. In other words, rather than summarizing the recent chart direction in a single sentence, the pattern first calls for checking the short fluctuation range, including the $412.55 low and the $421.94 high. This is seriously a box-range angle-check zone.

Market Concentration Is Both a Strength and a Variable

Another report said that as the foundry market expands, concentration around TSMC is intensifying, while Samsung’s second-half counterattack is drawing attention ^[3]. This shows that TSMC’s competitive advantage continues to stand out amid broader market trends. At the same time, since the possibility of a competitor’s counterattack was also mentioned, variables remain, and we cannot stop at the word “dominance.”

Looking at the 2nm MediaTek orders together with market concentration makes the story clearer. The key question is whether market concentration remains in place while customer acquisition continues; on the other side, the key axis is how quickly competitors’ actual responses emerge. Carrot believes we should view the qualitative signal of securing customer orders and the chart’s box-range movement separately, but ultimately verify both again through execution numbers.

No full buying, no full selling—act only when the support line breaks. This is not a sentence that dictates direction, but Carrot’s way of limiting excessive interpretation before the numbers are confirmed. The remaining questions are simple: when will the MediaTek orders translate into actual production and earnings indicators, and when will Samsung’s response move beyond possibilities in articles to concrete changes in customers and processes? ✨
