The last two implementations include calculation of the kalman gain. In Kalman Filter, we assume that depending on the previous state, we can predict the next state. The Kalman filter is underpinned by Bayesian probability theory and enables an estimate of the hidden variable in the presence of noise. But as the price becomes stretched, momentum slows, profits are taken and we often get mean reversion. A mean reversion strategy as above can then be applied to y. Analytics cookies. Furthermore, many of those stocks will have negative weight. stream Below is the equity curve of the linear mean reversion strategy from the previous post on the three-instrument portfolio with the value of the portfolio overlaid on the equity curve: The strategy suffers significant drawdown and only returns a profit factor of 1.04 and a Sharpe ratio of 0.29. 864 Practical Pairs Trading. they're used to gather information about the pages you visit and how many clicks you need to accomplish a task.
