The US technology market is facing another test. After attempting to recover from recent volatility, the Nasdaq 100 ETF $Invesco QQQ(QQQ)$ fell 0.68% on Tuesday as October inflation came in hotter than expected.
The latest CPI figures have raised concerns that inflation may not be cooling quickly enough to give the Federal Reserve room to ease monetary policy.
But is this the beginning of another technology sell-off, or just a temporary setback?
1. Inflation is proving harder to control
October headline CPI increased 0.4% month-on-month, above the 0.3% forecast, although lower than the previous month’s 0.6%.
Core CPI, which excludes food and energy, rose 0.3%, also above the 0.2% expectation. This is particularly important because core inflation provides a better indication of underlying price pressures.
Food prices increased 0.5%, shelter rose 0.3%, and energy climbed 0.7%.
The figures suggest that inflationary pressure remains present, even as the headline rate shows some moderation.
There is also an important data limitation: a year-on-year inflation rate cannot be reliably calculated because comparable prior-year data is missing.
Investors should therefore avoid drawing conclusions from an annual inflation figure that has not been established.
2. Treasury yields could determine QQQ’s next move
For technology investors, the biggest concern is what happens to interest rates.
Growth companies often have valuations based on profits expected several years into the future. When Treasury yields rise, those future earnings become less valuable in today’s terms.
This can put pressure on high-valuation stocks, even when their businesses continue performing well.
A higher interest-rate outlook could also increase financing costs for companies investing heavily in AI infrastructure and data centres.
However, one important distinction is that a 50-basis-point rate hike in December is not announced Federal Reserve policy. Market expectations can change quickly as new economic data becomes available.
I would watch the 10-year Treasury yield closely. If yields continue rising, QQQ could face further valuation pressure.
3. TMSC orders could provide a different sigmal
While inflation is creating uncertainty, the semiconductor industry’s underlying demand remains another important part of the story.
Taiwan Semiconductor Manufacturing Company (TSMC), listed in the US under ticker $Taiwan Semiconductor Manufacturing(TSM)$ , is particularly important because it manufactures advanced chips for major technology companies.
Its order trends, capacity expansion and management outlook can help investors assess whether AI infrastructure spending remains strong.
If demand for advanced chips continues growing, it could support the earnings outlook for semiconductor companies, even during periods of broader market weakness.
However, strong chip demand does not automatically guarantee higher share prices. Investors must also consider valuations, manufacturing costs and the possibility that customers eventually slow their spending.
4. What I would watch next
I would focus on three indicators:
Treasury yields: This is my first priority. A sustained rise could create additional pressure on high-growth technology stocks.
Core inflation: Investors need to see whether underlying price pressures begin moderating. Another hotter-than-expected reading could make the interest-rate outlook more difficult.
TSMC orders: Continued strength would support the longer-term semiconductor and AI investment story, although it may not immediately prevent a broader market correction.
My trading strategy
I would remain cautious with QQQ in the short term.
Rather than buying immediately after every market dip, I would wait for Treasury yields to stabilise and look for confirmation that technology earnings expectations remain intact.
For semiconductor stocks, I would distinguish between companies with strong order visibility and those whose valuations depend heavily on future AI spending.
I still see opportunities in the AI sector, but I would prefer gradual entries instead of chasing short-term rebounds.
Final thoughts
The latest CPI report highlights a difficult balance for the market.
Inflation is not rising as sharply as before, but it is also not cooling quickly enough to remove interest-rate concerns.
For QQQ, the next move may depend less on daily headlines and more on whether Treasury yields continue climbing.
At the same time, TSMC’s demand outlook will help determine whether the underlying AI investment cycle remains healthy.
My view is that higher yields could create short-term pressure, but strong earnings and semiconductor demand may provide longer-term support. The challenge is finding attractive entry prices without assuming that every pullback is a buying opportunity.
