Seasonal influences within the smaller end of the resources market can have a material impact on investment returns. The two months with the largest negative seasonal influences are June and, to a lesser extent, November. December has the strongest positive seasonal effect. The December effect is most pronounced late in the month (with some follow through into the first half of January). There is a chart at (VIEW LINK) illustrating the relative sizes of the monthly seasonal effects based on movements in the small resources share price index.
