Although Trump administration headlines changed by the hour, the big piece of news was a surprising and stunning rise in the trade deficit that sent shockwaves through GDP forecasts. While investors were fixated on inflation data Friday, the most significant surprise came from the advanced trade balance, which posted an unprecedented $37 billion deterioration—more than twice the magnitude of any month-to-month change over the last 50 years. This figure immediately raised concerns about economic growth, as trade deficits directly subtract from GDP.

The implications were clear: the first quarter is shaping up to be much weaker than anticipated. GDP estimates were revised downward, with the Atlanta Fed shockingly forecasting a negative -1.5% growth rate. That number is likely too pessimistic, as much of the trade imbalance reflects preemptive buying ahead of Trump's tariff threats, which will translate into higher inventories. Nonetheless, even more tempered projections of 1.0%–1.5% growth would mark the slowest quarter in over two years. Virtually all recent real economic data has surprised to the downside, including jobless claims, which unexpectedly spiked above expectations.

The bond market responded to these signs of weakness with the 10-year yield falling from 4.5% to the 4.25% range. A slowdown was anticipated, but these numbers are even softer than the Fed’s 2025 growth forecast. If this deceleration holds, rate cuts will be on the table sooner than later.

Turning to equities, we’ve seen a sharp selloff in the Magnificent 7 stocks, with NVIDIA at the center of attention following its earnings last week. The company reported results in line with expectations—no surprises, no disappointments—yet it still sold off Friday. This is indicative of a broader market rotation as investors take profits on high-flying tech and reconsider Value stocks. However, with economic growth slowing, it’s not clear that Value will significantly outperform. In a weakening economy, all stocks face challenges, though dividend-paying and more defensive equities may benefit from lower interest rates.

Sentiment remains highly bearish, with the VIX Index rising above 20—historically a signal of market caution, though not outright panic. The pessimism is palpable in survey data, with retail investors increasingly skeptical about the market’s direction. Historically, such extreme bearishness has often signaled buying opportunities, though timing remains uncertain.

Looking forward, the key question remains whether Trump will ultimately implement tariffs or pull back at the last minute. Regardless, uncertainty is already having a tangible effect on business behavior and market expectations. This week’s jobs report will provide some insight into whether this slowdown is temporary or part of a larger trend.

For now, the weight of uncertainty and slowing growth suggests continued volatility, with the bond market suggesting a more dovish Fed. If growth continues to weaken, rate cuts could arrive earlier than expected, providing a cushion for equities in the second half of the year. The primary trend in equities is still higher, but the likelihood of sustained rotation seems more likely now than any other time over the past couple of years.
