Twitter is facing fresh misery as US markets opened, with its share price diving to fresh lows... again.
Shares slipped more than four per cent lower to $14.87, stock under $15 for the first time ever, after speculation that the social network will make a major change to the way it works.
Under pressure chief executive Jack Dorsey was forced to put to rest reports that the chronological Twitter timeline would be switched for one controlled by algorithms which had caused uproar among users.
He suggested that a new timeline feature, similar to an existing "while you were away" section could be expanded but would not be mandatory.
The fall under the $15 mark is likely to fuel speculation that Twitter is a ripe takeover target.
It's due to update the market on fourth quarter earnings on Wednesday.
