U.S. stocks rallied Monday but gave back some early gains as small-caps and technology shares led the way amid the resumption of trade talks with China. The dollar fell to its lowest level since October and Treasury yields ticked higher with traders assessing the seemingly dovish remarks from Federal Reserve chairman Jerome Powell on Friday.

All major U.S. equity benchmarks ended higher. The S&P 500 Index added 0.7% after rising as much as 1.4% earlier in the session on strength in retailers, automakers and clothing companies. Amazon.com Inc. jumped 3.4%, pushing its market cap to $796.8 billion. It surpassed Microsoft Corp. as the world’s  largest public company after the software firm only edged higher by 0.1% for a value of $788.9 billion on Monday.

Both Amazon.com Inc. and Microsoft Corp. are now notably larger than Apple Inc., which had held the position for years. The iPhone maker now has a market cap of about $702 billion, down from a record $1.1 trillion in early October. The company has been pressured by weaker-than-expected iPhone demand in China. Last week, it cut its sales outlook, sending the stock to its lowest level since April 2017.

The biggest jump among major gauges came from the small-capitalization Russell 2000 Index, which picked up 1.8%. Meanwhile, the Nasdaq benchmarks rose more than 1% with telecommunications services and semiconductor shares pacing gains, giving the Nasdaq 100 Index its first back-to-back 1% gains since November.

“What you really, really want to see, are things like the Russell 2000 outperforming — and it is massively right now,” said Michael Antonelli, equity sales trader at Robert W. Baird. “You want to see the risky, risky stuff bouncing hard.”

Despite the enthusiasm, investors remain in a quandary after the wild end to 2018 in which the S&P 500 lost more than 9% in a month. Powell’s soothing comments on Friday and China’s moves to shore up its economy lifted sentiment somewhat, sending the S&P 500 up 1.9% last week, but risks remain. And U.S. lawmakers are still unable to reach agreement on a budget, leaving the federal government shut down for a third week.

“We have a respectable probability that Friday’s rally and the last week-and-a-half’s rally has more legs behind it,” said David Sowerby, managing director and portfolio manager at the investment firm Ancora, which manages $6.9 billion. “It’s Fed policy right now, that’s first and foremost the most important gauge impacting the market today. Trade issues, number two. A very distant number three is the government shutdown.”

Fresh trade talks between the U.S. and China helped sap demand for the greenback, while Treasuries slipped after a substantial retreat on Friday. The pound slid against the euro as U.K. lawmakers sought to avoid a no-deal Brexit. The common currency remained solidly up even as data showed German factory orders fell more than expected in November.

Elsewhere, emerging-market shares jumped, and the Indonesian rupiah led gains in major developing-nation currencies. Oil rose to the highest in three weeks, and gold climbed after China reported increased holdings.

Here are some events investors may focus on this week:

• A U.S. delegation is in Beijing for trade talks with Chinese officials, the first face-to-face encounter since Trump and Xi agreed to a temporary truce on Dec. 1.
• Wednesday sees the release of minutes from the Fed’s Dec. 18-19 policy meeting. Powell will speak to the Economic Club of Washington D.C. on Thursday.
