The Supreme Court’s Decision: A Catalyst for Market Ascendancy

by

Warren Buffett, that most esteemed figure in the realm of finance, has never claimed the mantle of oracle, nor does he presume to gaze into the murky waters of market fluctuations with prophetic clarity. In a reflective piece penned for the New York Times in 2008, he candidly confessed, “I can’t predict the short-term movements of the stock market. I haven’t the faintest idea as to whether stocks will be higher or lower a month or a year from now.” Such humility is not merely admirable; it is the hallmark of a true value investor.

In alignment with this sagacious philosophy, I too find myself adrift in uncertainty about the market’s immediate future. The fickle winds of fortune may blow any direction in the coming month or year, leaving me ill-equipped to assist in the dance of timing. Yet, as I peer into the horizon of this week, I venture a prediction: on Wednesday, January 14, 2026, the stock market may very well ascend-if, and only if, a singular event unfolds.

A Monumental Decision

Anticipation swelled among the observers of our nation’s highest court regarding a decision relating to President Trump’s imposition of global tariffs under the auspices of the International Emergency Economic Powers Act (IEEPA). Alas, such revelations did not materialize last week. However, the looming pronouncement from the Supreme Court on Wednesday carries with it the gravity of expectation, particularly concerning the tariff matter.

Behind these challenges linger three pivotal issues:

  1. The U.S. Constitution, that venerable document, entrusts Congress with the authority to levy taxes-tariffs being but a variant of such dues.
  2. The IEEPA, the legal framework invoked, conspicuously abstains from mentioning “tariffs.”
  3. While Congress has conferred upon the executive branch certain authorities concerning international trade, the president’s actions must be a response to genuine emergencies, a stipulation which critics argue Trump’s tariffs violate.

Two lower federal courts have already cast their judgment against the administration, and the online betting platform Polymarket suggests a 72% likelihood that the Supreme Court will affirm those decisions.

Trump, in a moment of exasperation shared on Truth Social, lamented, “If the Supreme Court rules against the United States of America on this National Security bonanza, WE’RE SCREWED.” Yet, others perceive the court’s impending judgment as a vital bulwark for the separation of powers so meticulously crafted by the architects of our republic.

Why the Stock Market Could Soar

Should the Supreme Court choose to challenge the tariffs instituted under the IEEPA, I foresee an exhilarating ascent in stock values on Wednesday. The mere reversal of these tariffs would elicit profound relief amongst investors, akin to a spring breeze after a long winter.

Mark Zandi, chief economist of Moody’s Analytics, has attributed the stagnation of the job market, in no small part, to the burden of these tariffs. On January 11, 2026, he articulated on X (formerly Twitter), “There has been no job growth… since Liberation Day last April,” following the announcement of significant reciprocal tariffs. Indeed, he posits that a declaration of unlawfulness regarding these tariffs would swiftly invigorate the job market-a notion that often resonates in harmony with the stock market’s fortunes.

Who, one might ponder, would stand to gain the most from such a judicial decision? One might consider Mattel (MAT 0.09%) and Nike (NKE 0.43%), both heavily reliant on imports from China, alongside UPS (UPS 0.03%), whose most lucrative routes traverse between China and the U.S.

Nevertheless, it is equally plausible that stocks less entwined with import dynamics may also experience a favorable jolt. The alleviation of tariff pressures could assuage inflationary fears, thereby granting the Federal Reserve the latitude to further reduce interest rates-a boon for myriad companies.

A Temporary Boost?

Yet, dear investors, let us not succumb to unbridled enthusiasm at the prospect of the Supreme Court dismantling the reciprocal tariffs. Treasury Secretary Scott Bessent has articulated concerns that the current administration may simply replicate the existing tariff structure by invoking alternative federal regulations.

Sections 301 and 302 of the Trade Act of 1974 empower the Office of the United States Trade Representative (USTR) to impose tariffs should investigations reveal unfair trade practices. However, legislative constraints might impede the administration’s capacity to enforce tariffs as broadly and effectively as it desires.

Thus, we find ourselves at a crossroads; it seems likely that additional tariffs will emerge to supplant any that may be overturned by the Supreme Court, should it rule against the White House. Consequently, any surge in the stock market post-ruling may be but a fleeting dalliance, a momentary glow before the inevitable twilight.
