Tariff fallout in focus after stocks' worst week since 2020: What to know this week

Stocks just had their worst week since a global pandemic brought the world economy to a halt in March 2020.

President Trump's shocking tariff announcements on Wednesday rattled markets ahead of the next day's trading session. Then, China's announcement of reciprocal tariffs sent stocks further lower on Friday . For the week, The Dow Jones Industrial Average ( ^DJI ) pulled back almost 8%, or about 3,300 points, to enter into correction territory.

Meanwhile, the S&P 500 ( ^GSPC ) sank roughly 9% as the broad-based benchmark approached a 20% drawback from its most recent all-time high. The tech-heavy Nasdaq Composite ( ^IXIC ) led the losses, cratering 10% and ending in a bear market as it's officially down 20% from its most recent all-time high.

In the week ahead, investors will watch for updates on the status of tariff negotiations with other nations, as well as announcements of reciprocal tariffs on the US. Trump's first round of 10% baseline tariffs is set to go into effect on April 5, and other wide-ranging additional tariffs are set to take hold on April 9.

In other news, big bank earnings slated for Friday will mark the unofficial start to first quarter earnings season. JPMorgan ( JPM ), BlackRock ( BLK ), Wells Fargo, ( WFC ), and Morgan Stanley ( MS ) are all set to release results. Delta ( DAL ) and Constellation Brands ( STZ ) will report on Wednesday.

In economic data releases, the Consumer Price Index (CPI) on Thursday is set to headline the week, with other releases on producer prices and consumer sentiment also in focus.

The 'bear case' becomes the base case

One key question on investors' minds is whether the stock market rout is over. Wall Street strategists have warned retaliatory tariffs would likely intensify the selling.

"If high tariff rates stay in place, negotiations are drawn out over a multi-month period and additional measures are taken with key trading partners, the risk of a recession/our bear case is likely to rise more materially," Morgan Stanley chief investment officer Mike Wilson wrote in a note to clients on Thursday night. Wilson's bear case projects the S&P 500 to end at 4,600, a level not seen on the benchmark index since December 2023.

Market experts have pointed out that the tariff retaliation fallout likely isn't over. RSM chief economist Joe Brusuelas pointed out to Yahoo Finance that the European Union, one of the US's largest trading partners, hasn't directly responded to the US tariffs yet. Brusuelas argued the market doesn't have "that priced in."

"Investors fundamentally think this is just a repeat of 2018," Brusuelas said. "So there's a lot more damage that could go on here."
