Stock markets are flat on Wednesday as market uncertainty lingers due to President Donald Trump's tariff campaign.

In 100 days full of surprises for investors, the S&P 500 and Dow nearly recouped their April declines – even with a worse-than-expect GDP report.

All this sound familiar? If the Trump tariffs stick around, it will likely be bad news for corporate profits, which means bad news for stock prices over the next few years. Of course, all these tariffs could be eliminated tomorrow, but if they do stick around the global economy will be negatively impacted.
