Societe Generale's uber-bearish strategist Albert Edwards has also argued that recent weak economic data from China "significantly increases" the risk of global deflation and believes that investors are ignoring the warning signs.
However, some remain optimistic that extra liquidity—provided by central banks around the world—would continue to help bolster equities in particular. Ian Harnett, a European analyst at Absolute Strategy Research, believes global stocks will rally another 20 percent in 2014, highlighting the optimal environment that policymakers have created.
