As the voting in the EU referendum swings from remaining to leave, ASX-listed UK-related stocks are getting smoked.

Fund manager Henderson Group plc (ASX: HGG) share price is down 4.7% to $4.83, while CYBG PLC (ASX: CYB) has lost 4.5% to trade at $5.29.

They aren’t alone, with the index S&P/ASX 200 (Index: ^AXJO) (ASX: XJO) down 1.9% and dropping rapidly, despite being up 0.8%.

The reason is that the vote for Britain to leave the EU appears to be heading toward Leave, despite bookmakers virtually pricing in the Remain vote as a guaranteed winner.

Most of the ASX 20 are getting hammered too, with banks and miners amongst the hardest hit.

However, with counting of votes still underway, there’s a chance the market could still swing around.
