Dow Soars Amid Inflation Calm and Quadruple Witching Frenzy

As of Friday afternoon, U.S. stocks showed a significant upward shift, with the Dow Jones Industrial Average surging over 700 points. This positive movement in the market was largely driven by the latest inflation data. The U.S. Personal Consumption Expenditures (PCE) index for November rose 2.4% year-over-year, slightly lower than the anticipated 2.5%, thereby boosting investor confidence.

The Dow climbed 754.65 points, or 1.78%, ending at 43,096.89. The Nasdaq gained 341.12 points, or 1.76%, closing at 19,713.89, while the S&P 500 increased by 99.92 points, or 1.70%, to end the session at 5,967.00. This upbeat performance reflects the market's optimistic response to the inflation data being less severe than expected.

It's worth noting that Friday featured the occurrence of a "quadruple witching" day, a quarterly event during which stock options, stock index options, and stock index futures all expire. This convergence typically heightens volatility and trading volume, creating lucrative opportunities for speculative traders. The event tends to induce significant market activity, especially in the closing hour of trading, often referred to as the "witching hour."

On this occasion, it was projected to be the largest expiration to date, involving over $6 trillion worth of equity and index options. In line with this, derivatives analytics firm Asym 500 estimated that approximately $6.5 trillion in options were set to expire, marking the most substantial expirations of the year and contributing to increased market movement.

Simultaneously, the PCE index's subdued rise—considered a crucial indicator by the Federal Reserve—emphasizes a declining trend in core inflation. The index's rise of only 0.1% month-over-month is the smallest increase since May, hence indicating a favorable trajectory for policymakers aiming for further rate cuts in 2025. Encouragingly, consumer spending in November saw an uptick, indicating persistent economic vigor, which influences the Federal Reserve's strategic outlook.

Moreover, an underlying issue impacting market sentiment was the re-emergent U.S. government shutdown crisis. Late Thursday, legislative measures backed by outgoing President Trump failed in the House of Representatives, interfering with the plans to avert a funding lapse for the government. This setback could potentially lead to a partial shutdown if no resolution is reached by Friday night.

A spending bill proposed has been contested within Congress, highlighting internal dissent, particularly among Republican members. The failure to pass this bill, which addresses a short-term extension of government funding alongside a suspension of the debt ceiling, means the risk remains unless an agreement is swiftly ratified.
