Investors on Wednesday bet that President-elect Trump and the Republican-controlled Congress will raise government spending and ease regulations on banks and energy producers.
The yield on the benchmark 10-year Treasury note reached its highest level in eight months, a sign that investors think the government will be issuing a lot of debt to pay for Trump's infrastructure priorities and other programs.
"The market is saying we are probably going to have more debt, maybe bigger budget deficits to finance some of this infrastructure spending and maybe some other initiatives and that could be inflationary down the road," said David Joy, chief investment strategist at Minneapolis-based Ameriprise.
Amid the bond sell-off, investors purchased stocks on U.S. exchanges, arresting a sell-off that started in overseas markets as presidential vote results came in late Tuesday night. U.S. stocks had fallen in eight of the previous 10 trading sessions.
"Everybody was talking of a 1,000-point sell-off in the market, but my opinion was you weren't going to get that because the market has already sold off into this vote," said Craig Johnson, senior technical market strategist for Piper Jaffray in Minneapolis.
The Dow Jones industrial average closed up 1.5 percent on Wednesday and the broad-market S&P 500 index was up 1.1 percent.
"This really set up to be one of those scenarios where you are selling on the rumor that Trump was going to win," Johnson said. "And now you are buying on the fact that you have this big change of ideology happening in Washington."
For several weeks, however, investors sold shares on days when it appeared Trump was moving ahead of Hillary Clinton in the race. The most recent stock sell-off intensified on Oct. 28, the day FBI Director James Comey said the agency was reviewing new information tied to the Clinton e-mail probe he had previously said was closed. And late Tuesday, as Trump's victory became clear, investors in Asia sold shares on the expectation that he would follow through on vows to seek new trade agreements and impose tariffs.
