Wall Street Has Its Best Week Since May 2025

The market had its best week since May, 2025, and for the first time since the Iran war began, the major indexes were back in positive territory for the year. Economic data showed the economy was not only holding up, it appeared to be accelerating in some areas. And on Friday, Iran declared the Strait of Hormuz open to commercial shipping, sending oil plunging and stocks to new all-time highs. Over the weekend, however, Iran reversed course, saying the strait would remain under its control until the U.S. lifted its naval blockade. Markets were closed when that news broke, which means Monday morning is where the reaction begins. That is where we are as this newsletter goes out.

What Drove Markets Last Week

Stocks moved higher all week on optimism that the conflict may be winding down, with Friday delivering the biggest catalyst: Iran’s declaration that the Strait of Hormuz was open to commercial shipping. Oil plunged and the S&P 500 closed at a new all-time high. It was a strong finish to a week that also brought encouraging economic data and broadly solid bank earnings.

The economic data last week was encouraging and deserves attention. First-look surveys of April business activity in New York and the mid-Atlantic region came in well ahead of expectations, suggesting the war may not be derailing economic growth the way some had feared. The same surveys also showed prices rising sharply, which means the inflation risk remains real and worth monitoring. The overall picture appears to be one of resilient growth, though the inflation outlook is not yet clean.

A separate inflation report on wholesale prices also came in better than expected. More importantly, two months in a row now, the rise in prices has been driven almost entirely by higher energy costs. Strip out gas and oil, and prices across the rest of the economy have remained relatively calm. That matters because it suggests the war’s impact on inflation may still be contained, and has not yet spread into the everyday cost of goods and services. The big banks that reported earnings last week offered a similar read on the economy: consumers were still spending, loans were growing, and business activity was holding up. In short, the economy appeared to be in good shape heading into this conflict.

The weekend brought a complication. Iran reversed its announcement about the Strait of Hormuz on Saturday, saying it would remain under Iranian control until the U.S. lifted its naval blockade of Iranian ports. Since markets were closed, Monday’s open is the first opportunity investors have had to respond. How that reaction plays out may set the tone for the week.

What to Watch This Week (April 20 – 24)

The economic calendar is relatively light this week, but the reports we do get are important because they may tell us whether higher gas prices are beginning to affect how consumers spend. The Iran ceasefire is also approaching its expiration, which means geopolitics remain the dominant backdrop.

KEY EVENTS THIS WEEK
Mon 4/20 Markets react to Iran’s weekend reversal • Alaska Air earnings
Tue 4/21 Retail Sales (April) • United Airlines, UnitedHealth, GE Aerospace, Capital One earnings
Wed 4/22 Tesla earnings • GE Vernova earnings
Thu 4/23 Flash PMIs (April) • Jobless Claims • Intel earnings
Fri 4/24 Michigan Consumer Sentiment (final April reading)

The two most important reports this week are Retail Sales on Tuesday and the Flash PMIs (Purchasing Managers’ Indices) on Thursday. Retail Sales will give us a sense of whether consumers appear to still be spending despite higher gas prices. The headline number may look elevated simply because gas is more expensive right now, so the more revealing figure is the portion that strips out gas, autos, and building materials, which gives a cleaner read on everyday discretionary spending. The Flash PMIs on Thursday will be the first national look at April economic activity and could show whether higher energy costs are beginning to weigh on broader business conditions. On the earnings side, airline results early in the week and Tesla on Wednesday may offer a useful real-world perspective on how businesses and consumers are navigating the current environment.

The Big Picture — What’s Really Going On

Here are the three things we believe every investor should keep in mind right now:

The economy appears to be holding up, but inflation is not yet fully contained. Growth data last week was stronger than expected, which is encouraging. However, the price surveys from the same reports spiked to multi-year highs, suggesting inflationary pressures may be building. The longer energy prices stay elevated, the greater the risk that those pressures could spread more broadly.
The market may be pricing in a resolution that has not yet occurred. Stocks closed at all-time highs even as the conflict continues, no final peace agreement has been reached, and the Strait of Hormuz has not fully reopened. The market is attempting to price what the world may look like in the months ahead. That is reasonable, but it also means that unexpected setbacks in the negotiations could weigh on investor sentiment.
The next two weeks may be among the most consequential of the year. The Iran ceasefire is nearing expiration, and the outcome of those negotiations could have a significant impact on oil prices, inflation, and the broader economy. Earnings season also shifts to Big Tech, which may help investors gauge whether corporate fundamentals support the optimism reflected in current market levels.
New all-time highs are good news, and we will take them. But experienced investors know that the first trip above a prior peak deserves a healthy amount of skepticism. We are monitoring the technical picture closely and will be watching this week’s price action for confirmation that the move is real. We will keep you posted.
