There’s something funky going on with shares in Wagners Holding.

Bloomberg data shows short interest in the $841 million construction materials group rocketed ahead of a sell-down by family owners and directors Denis and John Wagner. The four siblings – John, Denis, Neill and Joe – were major shareholders in Wagners with a combined stake of about 45 per cent.
