DXY (Dollar Index)

The DXY, or Dollar Index, measures how strong the U.S. dollar is compared to a basket of other major currencies like the euro, yen, and pound. Think of it as a report card for the dollar's overall health in global markets. You'll see it pop up in financial news because a stronger dollar affects everything from stock prices to commodity costs—when the dollar rises, American exports become pricier overseas, which can hurt certain companies' earnings. For example, if the DXY jumps 5% in a month, it might pressure tech stocks that sell heavily abroad, while making imported goods cheaper for U.S. consumers. Retail investors watch it to understand broader economic trends beyond individual stocks.
