The NASDAQ experienced a "thrilling moment"! Tech giants plunged after hours, and tech stocks may present a bottom-fishing opportunity!

On June 9th (Tuesday), U.S. stocks experienced intense volatility during trading, with the NASDAQ rising over 1% at the open, then plunging more than 1,200 points intraday, with the largest decline approaching 4%, before the decline significantly narrowed; the Philadelphia Semiconductor Index dropped over 8% at its worst. By the close, the three major U.S. stock indices showed mixed results: the Dow rose 0.17%, the NASDAQ fell 0.97%, and the S&P 500 declined 0.26%. This contrasted sharply with the broad rally the previous day. I believe that upcoming tech stocks may show a volatile adjustment trend, and tonight’s U.S. CPI data could serve as a catalyst for a market turning point.

I still hold most of my tech stocks and some defensive sector stocks recently, with the specific position distribution as follows:

NVIDIA

Cost basis: 214

Position share: 30%

Current price: 205.1

Loss: -5%

Micron Technology

Buy-in price: 1015

Position share: 20%

Current price: 864

Loss: -15%

Microsoft

Cost basis: 441

Position share: 30%

Current price: 416.6

Loss: -8%

UnitedHealth

Buy-in price: 379

Position share: 20%

Current price: 391

Loss: 6%

Currently, the outlook for U.S. tech stocks is uncertain. The CPI data for May to be released tonight could be a decisive factor for a sharp rise or fall in the short term. If the data exceeds expectations tonight, the rate hike expectations will surge again, and U.S. stocks are likely to pull back, with tech stocks bearing the brunt; conversely, the market may rebound again. My next operational approach is "reduce positions, keep cash as king"—sell some tech stocks on rallies, hold cash, and wait for another big dip to buy the dip. For defensive sectors like UnitedHealth, I will hold steady, optimistic about a wave of catch-up rally.

AI tech stocks are entering deep waters, and giants are beginning to team up. Regarding the future, I believe that the long-term outlook for AI chip concept stocks still has support, but short-term volatility will intensify, and the market will show structural differentiation. On one hand, the global semiconductor market has entered a high-growth cycle driven by AI, with the World Semiconductor Trade Statistics (WSTS) raising the 2026 global semiconductor industry growth forecast sharply to 90%, reaching a total scale of $1.51 trillion, mainly driven by AI infrastructure and graphics acceleration computing demand. In Q1, AI chips and storage-related companies accounted for most of the industry’s growth, with NVIDIA and the five major memory giants achieving a combined revenue growth of 49% year-over-year, and companies generally giving strong growth expectations for Q2: Micron expects 40% revenue growth, NVIDIA 12%, and the robust demand has been validated by performance.

On the other hand, the overall valuation of global tech stocks is currently high, and institutional holdings are overly crowded. Previously, the AI sector experienced a prolonged rally, and after the rebound on June 8, the next day saw chip stocks surge and then retreat collectively, reflecting increasing market divergence. Under the background of marginal liquidity tightening, the market will rely more on earnings realization, and the space for purely thematic speculation will be compressed. Funds will focus on targets with actual orders and strong performance. Additionally, the upcoming listing of companies like SpaceX and OpenAI in the next six months may divert market liquidity further, intensifying sector differentiation. Moving forward, investors should avoid high-valuation pure speculation targets and focus on segments with strong order certainty, such as optical modules, storage, and leading semiconductor equipment companies with good performance.
