An advert for a recently launched initial public offering app in Australia opens with a smug-looking banker turning to the camera and asking: “Are you thinking of investing in an IPO?” before continuing: “Of course you’re not, that’s for guys like me – the insiders, the one per cent. Right? Wrong.”

The actor - who then bizarrely strips down to his boxer shorts - goes on to explain that new app OnMarket BookBuilds lets people buy shares in IPOs and placements from their smartphones, tablets or desktops.
