Twitter's stock hit an all time low yesterday, and although it's rebounded about 1% this morning, the stock is still trading below $30 per share, making the company worth around $20 billion. That could make it an attractive acquisition target, although some analysts think it will have to lose another $10 billion in market cap before pontential buyers like Google and Facebook take a serious look.
The stock dropped 15% last week after a disastrous earnings call where interim CEO Jack Dorsey and CFO Anthony Noto sounded pessimistic about the company.
As you can see on this lifetime stock chart from Statista, Twitter hit its all time high in Dec 2013, less than two months after going public. It dropped below $60 per share in Feb 2014 after its first earnings report and has never reached that price again.
