April 2025: A Month of Reversals and Resilience Across Markets
Monthly Market Commentary
By Kensington Asset Management Team
stock Market
The stock market endured one of its most volatile months in years. The S&P 500 fell 21.35% from its February 19 peak of 6,147.43 before bottoming on April 7 at 4,835.04, shortly before the Administration announced a 90-day pause on new tariffs (excluding China). Markets quickly rebounded on the news, with the S&P 500 soaring 9.52% on April 9, its largest single-day gain since October 2008. The Nasdaq Composite jumped 12.16% the same day, marking its biggest one-day percentage gain since January 3, 2001, and the second-largest on record.
This dramatic reversal fueled an intra-month rebound, with the S&P 500 ultimately finishing the month down just -0.76%, despite having been down as much as -13.84% earlier. The Nasdaq Composite managed a modest gain of 0.09%, while the Russell 2000 declined -2.38%, mirroring the return of the S&P 500 Equal Weighted Index. Meanwhile, the mega-cap tech-heavy Nasdaq 100 posted a monthly gain of 1.52%.
In late April, the market, as measured by both the NYSE Composite Index and the S&P 500, triggered a Zweig Breadth Thrust (ZBT), the 17th occurrence since 1950. This rare technical signal is generated when a 10-day moving average of advancing issues jumps from below 40% to above 61.5% in just 10 trading days. Historically, the S&P 500 has been higher six months and one year later in every prior instance, with an average one-year gain of 23.78%.

While past results are encouraging, it’s important to note the relatively small sample size of prior signals. A broader historical lens, including periods like the Great Depression and post-WWII recovery, shows more mixed outcomes, underscoring the importance of interpreting such signals in context.

Fixed Income
Bond markets were mixed again in April, echoing the performance trends seen in March. Shorter-duration Treasuries delivered gains, with 2-year and 5-year yields up 0.82% and 1.36%, respectively, while the 10-year Treasury returned 0.78%. In contrast, the 30-year Treasury declined by -1.38% for the second month in a row. Bloomberg US Mortgage-Backed Securities Index posted a slight gain of 0.29%, and both Bloomberg US Corporate Investment-Grade and High-yield Indices were little changed, at -0.03% and -0.02%, respectively.
The 30-year Treasury continues to reflect crosscurrents in the macroeconomic landscape. One factor may be a gradual rebalancing of global portfolios, as investors reassess long-term exposures following a decade of strong US outperformance. In addition, policy shifts such as increased tariffs, changes in defense spending expectations, and ongoing discussions about the dollar’s international role may also be contributing to evolving investor preferences.
Another consideration is the potential for structurally higher inflation, driven by factors including onshoring of supply chains, a higher baseline level of tariffs, immigration policy, and a growing fiscal deficit. These dynamics could eventually lead to changes in how deficits are financed. Should interest costs continue rising, there may be renewed debate around tools like yield curve control to manage long-term borrowing costs, a strategy that historically has trade-offs, including inflation risks.
Federal Reserve and Monetary Policy
As expected, the Federal Reserve left interest rates unchanged at its most recent FOMC meeting (May 6, 2025), citing a desire to see clearer evidence on the trajectory of inflation and growth. A key question remains whether the latest round of tariffs will lead to a temporary increase in prices or contribute to more persistent inflationary pressure, a scenario the Fed is keen to avoid.
There are already indications that price increases may be broadening beyond directly affected goods. Even so, official inflation data has continued to trend lower. Both the Personal Consumption Expenditures (PCE) and Consumer Price Index (CPI) reports came below expectations.

The AMP Pipeline Inflation Indicator, which incorporates commodity prices, shipping rates, Purchasing Managers’ Index (PMI) surveys, and China’s PPI, is currently signaling inflation just above 2% year over year.

Taken together, recent data suggests that the inflation outlook remains relatively stable. In a different policy environment, absent the uncertainty surrounding tariffs, the Fed might have more flexibility to consider rate cuts. For now, the focus remains on monitoring inflation developments and economic resilience in the face of shifting trade dynamics.
