Feted job outsourcing site Freelancer and a little-known company building an indoor skydiving centre in Sydney’s west have provided the most breathtaking returns of this year’s floats.

Freelancer shares are up 268 per cent since listing on Friday, while shares in Indoor Skydive Australia Group have almost tripled since listing in January. They are the top two ­performers of the more than 30 companies floated on the stock exchange to date this year.
