Bank of America Merrill Lynch said, investors ploughed $14.2 billion into global equity funds this week, the largest amount in a year as investors jumped on to 2019's stock market rally.

An index of global stocks is up more than 16% since the end of 2018 as falling market volatility and a renewed dovishness from global central banks, led by the U.S. Federal Reserve has boosted risk appetite across the board.

BAML said most of the inflows went into exchange traded funds while mutual funds saw net outflows. U.S. equity funds were the biggest beneficiaries with net inflows of $25.5 billion while emerging markets saw net outflows. European funds also saw $4.6 billion of outflows after the ECB slashed its growth forecasts.
