Reuters reports that BofA's monthly investor survey showed that investors are in "full bull" mode, deploying more money into emerging markets, small-cap stocks and the banking sector on hopes a COVID-19 vaccine will turn around these hard-hit market segments.

The euphoria sent investors' cash levels down to 4.1% in November, from 4.4% last month, to pre-COVID-19 levels last seen in January, according to the survey of 190 fund managers with $526 billion in assets under management.

With global economic growth and profit expectations running at a 20-year high among the investors surveyed, the "reopening rotation" into oversold business sectors is likely to continue in the fourth quarter, BofA said.

For 2021, investors named being "long" emerging market assets, S&P 500 and oil as their favourite trades.
