It took Twitter just seven years to grow from a single tweet to the $30 billion company that held its initial public offering in 2013. The stock's IPO priced at $26 per share and closed its first ever trading day at $44.90.

As long-time Twitter investors know all-too-well, the company struggled to find its footing in the public market, dropping to an all-time low of $13.73 in May 2016. The stock trades around $37.77 at press time.
