According to a number of opinion polls, Biden’s support rate continued to maintain a stable lead over U.S. President trump on the eve of the National Congress. These polls, at least in part, reflect Biden’s influence in choosing Senator Kamala Harris as his running mate. According to a poll on Sunday, Biden led by 9 percentage points. Biden’s approval rating was 50%, higher than Trump’s 41%. In addition, according to cbsnews’ nationwide poll of voters, Biden is 10 percentage points ahead. Biden is also 7.9 percentage points ahead, according to the average of the real clear politics poll, which contains the latest results. In the survey, Biden led trump by 7 percentage points in 11 states, including Arizona, Colorado, Florida, Maine, Michigan, Minnesota, Nevada, New Hampshire, North Carolina, Pennsylvania and Wisconsin. The former vice president of the United States is ahead of trump on most major issues, including who can better deal with the epidemic, while trump has a double-digit lead in dealing with the economy. < / P > < p > 58% of respondents who supported Biden admitted that voting was more about “opposing trump” than “supporting Biden.”. Only 38% of respondents said they voted for Biden. 74% of respondents who supported trump said that the purpose of the vote was to support trump, not to oppose Biden. However, Biden was 11 points ahead of trump in the same poll last month. As a result, Biden’s lead has declined this month. Biden’s approval rating has been higher than Trump’s since July last year. The ethnic groups supporting trump and Biden differ greatly. Specifically, 88% of black voters support Biden, which is much higher than 8% of Trump’s; 57% of Latino voters support Biden, which is also higher than 31% of trump’s. However, among the white group, Trump’s support rate was 49%, higher than Biden’s 42%, while among the white people who did not go to university, Trump’s support rate was 59%, much higher than Biden’s 27%.

In addition, among centrist voters, Biden’s approval rating was 49%, higher than Trump’s 25%. Analysts point out that with the National Congress next week, the election season will enter a more intense phase. Investors have also begun to adjust their portfolios for possible market movements ahead of the US presidential election. Although this year’s election has always played an important role in the minds of investors, its impact on the market has been overshadowed by the coronavirus pandemic and unprecedented stimulus measures by US policy makers. However, investors said the situation could change in the coming weeks. < / P > < p > they are concerned about a range of possible outcomes, including competition between President trump and presumptive presidential nominee Biden, which may lead to results that cannot be determined immediately or even disputed. Some investors are increasing cash positions or betting on increased volatility. < / P > < p > “there are good reasons to believe that the election results will be delayed,” said Lamar villere, portfolio manager at Ville & Co. “This will show cracks in the market that have been priced based on perfect results.” < / P > < p > Ville’s companies have raised their cash positions to 20% of their asset size to hedge against election induced stock market shocks. Some say the stock market is already highly valued – the S & P 500 has risen more than 50% from its year-end low, and the expected P / E ratio is at its highest level in about 20 years. < / P > < p > some investors believe that market performance in the coming months may predict which presidential candidate will win in November. Data from TD securities dating back to 1930 show that, three months before an election, if the S & P 500 goes up, incumbent presidents tend to win. That could be bad news for trump. Although the S & P 500 is up about 3% this month, the three months since August have historically had the worst performance of the year, with historical average returns of about zero, according to BofA global research. Analysts say Biden’s chances of winning the presidential election and pocketing both houses of Congress could put Wall Street’s favorite trump policies at risk, such as lower corporate taxes and deregulation. “The potential impact of Biden’s presidency in the future may initially unsettle the market,” Oxford economics analysts said in a recent report. < p > < p > according to JP Morgan, a proposal to increase the corporate tax rate to 28% may reduce the profits of S & P 500 enterprises by about 5.5%, reduce capital expenditure by about $50 billion, and reduce the scale of share repurchase by $100 billion in 2021. In addition, the Biden administration may not be like trump, which will help international and emerging markets outperform US stocks in the coming year, said Stuart Katz, chief investment officer of Robertson Stephens wealth management. At least one of Biden’s flagship policies, an increase of $2 trillion in infrastructure spending, could further depress the already weakened dollar, according to the Oxford Institute of economics. Investors should also be prepared for the possibility that trump may have doubts about the authenticity of the vote or may simply withdraw from the election, Joseph Amato, chief equity investor at Neuberger Berman, wrote in a recent research report. Trump tweeted at the end of July suggesting that the general election might be postponed until people could “vote properly, safely and safely”, which raised concerns about the election. “The more he lags behind in the polls, the more inflammatory his decisions are likely to become,” Amato wrote.
