HONG KONG: Markets were mixed Monday as investors struggled to maintain an initial rally, with falling infection rates and more good news on the vaccine front playing off against worries about high valuations and inflation.
While the United States is approaching 500,000 deaths, there is growing optimism that there is light at the end of the tunnel in the Covid-19 crisis as governments embark on immunisation programmes that will allow economies to reopen.
Expectations that President Joe Biden's vast stimulus will be passed next month are also keeping spirits up, as a raft of data last week on factory and services activity indicated the financial hit to the United States and Europe might not be as bad as feared.
News that the Pfizer/BioNTech jab appeared to prevent nine in 10 people from getting the disease in Israel -- which is the most advanced in its rollout -- provided a positive background. Israeli officials also said the shot was 99 percent effective at preventing deaths from the disease.

And Simon Ballard at First Abu Dhabi Bank warned that more big gains in stocks are "going to create increasing levels of concern".
He added: "It's driven by, on one side, stimulus expectations from Mr Biden and also the expectation of that continued dovish rhetoric and more acceptance of early stages of inflation from the Fed before even thinking of moving to a tightening bias."
Investors are keeping tabs on China-US relations after Biden called on European allies to stand up to political and economic challenges from Beijing, adding: "We can push back against the Chinese government's economic abuses and coercion that undercut the foundations of the international economic system."
