It’s been the best of times or the worst of times for bankers working on London listings this year, depending on which end of the stock market they operate at.

Dealogic data published on August 11 shows that the money raised by companies listing on London's junior AIM market so far in 2016 is up 72% year-on-year to $1.2 billion. That is more than was raised on AIM in all of 2015 and the second highest level at this point in eight years.
