The arrow on this risk profile bar shows the risk of the fund as measured by standard deviation. Standard deviation measures the risk of a fund by telling you how, on average, the performance of the fund moves away from the mean.
A high standard deviation indicates that the performance varies a lot, whereas a low standard deviation tells you that the performance has been more stable. The funds falling in the Low range have standard deviations between 0 and 13.34, in the Moderate range between 13.34 and 26.67, and in the High range above 26.67.
