Investors started to sell off sales in Facebook, Apple and other tech companies last week, before enjoying a brief reprise on Monday. However, a drop in the share prices of tech companies continued overnight.
Goldman Sachs was recommending investors “sell” shares in Apple, while Tesla recorded its worst day of trading in the firm’s history.
The sell offs are likely to impact the FTSE 100 at the start of trading today.
The London market suffered yesterday due to the sell offs and due to the uncertainty over a no deal Brexit spooked investors.
After making gains on Monday it was unable to continue the bull run.
The Index clung to its opening mark, down 7.1 points or 0.1 percent at 5930.3.
