The U.S.stock market experienced a notable decline on January 7th,with all major indexes closing in the red.The tech-heavy Nasdaq Composite fell by 1.89%,the S&P 500 dipped 1.11%,and the Dow Jones Industrial Average decreased by 0.42%.This downturn raises questions about the underlying factors influencing market sentiment.What insights can experts provide regarding this shift in market dynamics?

One significant trigger for the market's rapid descent was the release of two unexpected economic data points,which fueled a wave of panic among investors.According to Zhang Antian,a senior macroeconomic analyst at the Research and Development Center of CITIC Securities,the yield on the 10-year U.S.Treasury note approached 4.7%,indicating increased borrowing costs that catalyzed a pullback in stocks.This shift comes after a period of speculation regarding potential interest rate cuts by the Federal Reserve,which saw expectations shift from the prospect of 2-3 rate cuts in 2025 to predictions that no cuts would occur in the first half of that year.Zhang attributes this drastic recalibration to the simultaneous release of key economic indicators on January 7th that suggested a stronger-than-expected economy,thereby diminishing the urgency for rate reductions.

One of the crucial reports was the December ISM Services PMI,which registered at 54.1%,thereby exceeding predictions.Within this report,a particular price index surged to 64.4% from a previous figure of 58.2%.The surge in the services PMI was largely driven by business activity and delivery times,with reporting firms hinting that seasonal effects typical of year-end contributed to this.However,market focus turned sharply negative due to the combined strength of both the prices and labor markets,raising fears of persistent inflation.

Additionally,the November job vacancy rate rebounded to 4.8%,a figure that also exceeded expectations.The simultaneous release of both data points severely rattled the markets,as prior concerns about a cooling labor market were seemingly unfounded.Unemployment trends indicated a decrease,raising fears of fewer than two anticipated rate cuts by the Fed in 2025.However,even in such a scenario,the robust labor market alongside easing inflation could support real income growth among households,thus providing some cushion for market sentiment.

As Zhang Antian notes,market dynamics are likely to be influenced by more than just these two indicators in the coming days.While inflation and labor market rebounds are concerning,shifting expectations regarding Fed policy and overall economic fundamentals introduce opposing pressures.The Treasury market exhibited significant volatility,leading to apprehensive trading conditions.Investors are awaiting the upcoming unemployment data set for January 10th,which will likely determine the market trajectory unless there is major commentary from Fed officials before that date.

Looking ahead,Zhang believes the initial market reactions were exaggerated.For instance,job vacancies have largely surged in professional and business services without similar growth in manufacturing or the leisure and hospitality sectors — where vacancy rates fell.Moreover,market trends post-January will likely be shaped by additional events,including comments from Fed Chair Powell on elevated interest rates or fluctuations related to the Japanese yen.

Technology stocks were at the forefront of this downturn,with NVIDIA leading the charge.The semiconductor giant witnessed a dramatic decline of over 6%,marking its worst single-day drop since September 2024.Tesla and Amazon followed suit,falling by 4% and 2%,respectively.The timing of NVIDIA’s drop is particularly striking as it coincided with the start of the Consumer Electronics Show (CES) in Las Vegas,where its CEO,Jensen Huang,unveiled several significant technological advancements.What prompted this abrupt market drop against such a backdrop of innovation?

Wu Zhaoyin,chief investment officer at Dongwu Futures,elucidated this occurrence by examining two layers of the market's psychology.Firstly,despite the announcement of favorable technological innovations from NVIDIA,the stock responded negatively,indicative of a market phenomenon where 'good news is often seen as already priced in.' Essentially,the market had fully absorbed this optimism prior to the announcements; thus,the realization of these expectations led to selling pressure.

Secondly,the broader market conditions also play a role.Stocks in the tech sector saw substantial downturns due to shifting sentiments about U.S.monetary policy.The expectation that inflation could remain persistently high raised concerns that the Fed might slow or even halt rate reductions,leading to prolonged periods of elevated interest rates.Such conditions could pose considerable pressure on high-valuation tech stocks.

NVIDIA has historically shown strong performance,and its share price surged in recent years,currently boasting a rolling P/E ratio of 54.If continuous high earnings growth were to occur alongside decreasing Fed rates,maintaining a P/E ratio above 50 might be plausible.However,should rates continue to rise unexpectedly,such lofty valuations would face challenges in being justified.Furthermore,if NVIDIA's expected earnings fail to materialize,its share price could swiftly correct downward.

Investor sentiment surrounding NVIDIA remains cautiously optimistic.After Huang's showcases,there's still hope for sustained growth bolstered by recent innovations.The current market declines,however,suggest a reassessment of what those high valuations entail,particularly against the backdrop of enduring high U.S.interest rates — even as overall risk-free rates may elevate in 2024.

In the wake of these developments,Federal Reserve Governor Lisa Cook issued an unusual warning regarding the risks facing the stock market.Cook expressed concerns about the potential for significant downturns influenced by adverse economic news or shifts in investor sentiment.With October job vacancies and services data exceeding expectations,the market's focus turned again toward the upcoming non-farm payroll data set for January 10th,examining its implications on future stock trends.

As Financial expert Hu Jie from Shanghai Jiao Tong University analyzes,the U.S.economy showcases a relatively healthy momentum as the New Year begins.Although Cook's comments have spooked the markets,Hu does not share an excessively pessimistic view.The unemployment rate hovers around 4.2%,a historically low figure,and various employment metrics display overall positive trends.

On the inflation front,the past two years of stringent conditions are showing signs of effective management,with the Consumer Price Index (CPI) up merely 2.7%.However,the slow downward trajectory and occasional spikes in inflation remain areas of concern.Therefore,observing these developments is crucial to understanding the public sentiment regarding the economy.

In reviewing the stock market landscape,Hu observes that fears surrounding high valuations indeed weigh heavily.The S&P 500's average P/E ratio stands at 22,signifying elevated market expectations.However,many overvalued stocks are restricted to a limited number of high-tech companies.Hence,the market does not necessarily reflect an overall state of overvaluation as indicated by the P/E ratio alone.Moreover,while triggers could prompt revisions in sentiment leading to corrections for these high-valuation stocks,Hu believes that a substantial reversal akin to the early 2000s tech bubble burst is unlikely given the current economic context and impactful ongoing technological advancements.

In summary,despite the existence of risk factors such as inflated stock valuations and potential liquidity constraints adversely impacting market confidence,Hu maintains a stance of cautious optimism.He contends that if a downturn does occur,it is more likely a transient correction rather than an overarching reversal,underpinning the resilience of the U.S.market amidst rapid changes.
