Global markets fell overnight as market jitters arising from the plunge of Turkish currency continued to spread.

The Dow Jones index fell 125 points, or 0.5 per cent, to 25,188.

The S&P 500 lost 0.4 per cent and the Nasdaq slipped by 0.25 per cent.

Technology and “FANG” stocks — the digital giant cohort of Facebook, Apple, Netflix and Google — defied the trend, with Apple and Amazon gaining more than 0.5 per cent each.
