Hedge fund manager Marcel Melis ignores stock charts, commodities reports and bond prices as he sips his morning coffee. All his attention is focused on one thing: the weather.

Melis analyzes forecasts for areas from the snow-capped mountains of Norway to the beaches of Spain’s Costa del Sol to predict changes in demand for power and gas. The founder of Energy Capital Management BV, which has raised $60 million and started trading in October, targets returns of 25 to 30 percent.
