Volumes in Brisbane Broncos Limited have picked up significantly as finals season approaches. More than 50,000 shares changed hands during the week, heavy volumes for a stock that sometimes goes weeks without trading at all. The main reason for the lack of trades is an exceptionally tight shareholder register, with News Corp controlling about 69 per cent of shares on issue. The company reported a near 5 per cent jump in half-year revenues to $14.3 million, while profit almost doubled to $795,428. Average crowds fell to 30,073 from 32,665. Finals chances aside, investors weren’t too thrilled, and the stock fell about 7 per cent during the week.
