After last year's tranquillity, as the charts below show, investors have had it all thrown at them this quarter, from the biggest ever rise in stock volatility <.VIX> to rapidly escalating tensions over global trade, deepening turmoil in the White House and major tech sector wobbles.
A "melt-up" that sent the MSCI's world share index up 8 percent in January suddenly evaporated. Now the Dow Jones <.DJI>, S&P 500 <.SPX>, FTSE <.FTSE> Nikkei <.N225> and scores of other big markets are all down for the year.

It is one of the reasons that stocks have been shaky of course, and it remains one of the main things shaping many investors' view on the rest of the year.
"One thing that it is going to be important to get right now is where to be when bond yields are going up," said SEB investment management's global head of asset allocation Hans Peterson.
"We are rotating from the old regime of low interest and growth stocks like the FAANGs into a new world... and that creates volatility."
