U.S. stocks opened higher on Thursday, rebounding from a broad decline in the previous session as the tense trading relationship between the U.S. and China once again appeared to ease. The Dow Jones Industrial Average rose 0.6%. The S&P 500 added 0.4%. The Nasdaq Composite Index was up 0.5%. All three are on track for their fifth rise of the past six sessions. Sentiment may have been boosted by signs the U.S. and China are willing to resume trade talks, which could end up in a bilateral agreement. Bloomberg reported late Wednesday that officials from both countries have raised the prospects of restarting a conversation at a high level. Investors are concerned that a full-on trade war could act as a major headwind to growth. Among the most active stocks on Thursday, Broadcom Inc. agreed to buy CA Inc. for more than $18 billion. Shares of CA spiked 18% while Broadcom lost 15%.
