Investors of SkyCity Entertainment should start asking more questions about whether it's time for a change at the top of their company. The share market reacted positively to news that long-time chief executive Evan Davies was to embark on a corporate slash-and-burn-exercise to cut costs. Davies had been under pressure since SkyCity's extremely poor half-year profit result back in February, when the casino company posted a 23 per cent fall to NZD 45 million and cut dividends by 25 per cent to nine cents a share.
