How is the weakening dollar affecting your portfolio? The world’s reserve currency fell sharply in the first half of 2025, making it a bruising year. It has recovered some but still sits below where it started the year. Other currencies like the euro, Japanese yen, and Mexican peso look stronger against the greenback. Several factors could influence whether the dollar roars back or recedes. Why should the dollar’s performance matter for everyday investors like you? Morningstar Indexes strategist Dan Lefkovitz explains why and what you can do to protect your portfolio from currency fluctuations.

The bifurcation of the stock market is appearing to divide investors into two camps. There’s a lot of optimism baked into share prices of firms seen as leaders in artificial intelligence, according to Dan Kemp, chief research and investment officer at Morningstar Investment Management Europe. The Market Brief author points to Tesla TSLA as a great example, since investors are ascribing significant value to the company’s unproven, future products. Meanwhile, there’s a lot of pessimism in parts of the market that are not involved in AI. Kemp reminds investors to look for undervalued opportunities in the unloved areas of the market.
