The goals of the course, for students/academics, professionals, and algo traders, and general background to the course. Realistically speaking, spot rates tend to stay put, and random walks are much more likely than having realised forwards. 03:58 Having proved results about the skewness of momentum returns over different horizons, we apply it to an exponentially weighted moving average (ewma) rule, showing how the peak skewness is related to the effective lookback (in our case, the "span of the ewma.
