The table below shows the monthly frequency of company flotations (IPOs) and listing on the London Stock Exchange. The dark bars show the month frequency for all flotations of companies currently listed on the LSE, and the lighter bars are limited to just the 162 companies floated from the beginning of 2010 to 2015.

The second most popular month has been July (11%). By contrast the least popular month is August, followed by February and September.

This profile has changed somewhat in recent years. Since 2010, the two busiest months for flotations have been June and July (13%), followed by March. And, oddly, January is now the least popular month for flotations (3%).
