Even after an extended trading delay, Tesla had its busiest day on the stock market since 2014.

Some 30.4 million shares traded hands on Tuesday, after CEO Elon Musk put out a surprise tweet announcing his intention to take the electric car company private at $420 a share. It was the most active day for the stock since February 2014, according to FactSet, and fifth busiest all time for Tesla, which went public in 2010.
