Investing in internet content providers at the moment is a difficult art to master. A case in point is King Digital Entertainment, which has filed for a 500m-dollar initial public offering on the NYSE. Mobile devices continue to proliferate and content is needed. However, barriers to entry are low and consumers' tastes can vary quickly as the fate of sector peer Zynga shows. Its well-known Farmville game became a craze and then crashed. Even so, King is a highly profitable company and its revenues are growing. Yet both metrics are presented to investors on fuzzy adjusted measures. As well, the majority of the company's sales come from its one famous game - Candy Crush. An example from the past from the above sector peer may be useful. Shares of its rival are off two-thirds since their 2012 peak. "Public investors are assuming venture capital risk without the upside. Some games are impossible to master," says The Financial Times' Lex column. Oil services outfit Wood Group yesterday delivered slightly weaker-than-forecast full-year results. Following on the heels of two profit warnings, however, investors were cheered by the fact that trading had not deteriorated further at its key engineering division. The unit, which provides equipment and pipelines and performs maintenance tasks, accounts for 46% of the firm's profits and a third of its revenues. As well, Wood Group upped its full-year dividend pay-out by 22% - that was better than expected. The company's stated intention is to increase it by a further 25% this year and another 10% in 2015. Significantly, the so-called dividend cover is 4.5 times. However, profitability is set to drop again in Engineering in the year ahead, as a result of weakness in the Canadian oil sands industry. The GTS division, which provides portable power generators, saw profits decline by 9%. Given the declines in those two divisions - which together contribute 61% to the 'bottom line' - the shares remain a 'hold' until evidence is forthcoming that a floor has indeed been put in place, says The Daily Telegraph's Questor team.
