Exploring mean reversion and cointegration: part 2 [Robot Wealth] In the first post in this series, I explored mean reversion of individual financial time series using techniques such as the Augmented Dickey-Fuller test, the Hurst exponent and the Ornstein-Uhlenbeck equation for a mean reverting stochastic process. The Kalman filter is a state space model for estimating an unknown (‘hidden’) variable using observations of related variables and models of those relationships. Would the hedge ratio change fast enough during real time trading to save me? ... Do you think my problem might be solved by using a Kalman filter as suggested, to come up with dynamic hedge ratios? Thus, we propose a new approach for online portfolio selection, namely W-KACM, to capture the properties of mean reversion and momentum in stock prices. 2) Yes, but no cointegration test allows you to test more than 12 stocks. /Length 10 0 R One suggestion is to use a filter rule to supress trade signals generated at times when the noise ratio is too large, and/or to increase allocations to pairs in which the noise ratio is relatively low. Both research studies follow a very similar path, rejecting beta estimation using rolling regression or exponential smoothing in favor of the Kalman approach and applying a Ornstein-Uhlenbeck model to estimate the half-life of mean reversion of the pairs portfolios. ���ј�b.Qp�l �р�+9� �y*1�CH�P�����S��P3�M@�h�q!B��p�"#�8X�E$��Ŵa��b9�š���Y.+�'A�� 0� fa��n�&á��`7�؀�gk�Cx�bT��Fta�[9)*x@2��LҌ2��"2���h3Z�����A���ؙ]$�d��l�Hb5�`�a��(7���1�@e9���Cy�` ���:�Wm��rrZV^�1���Q�@-��k��5��p0��&�.��7�ϛV�+�0�7������6lZ�����h�a h)л�4�#H�2�c�X��#�:�Kj��pƷ�@ �����7�Ø\�/J�놁�f�6�b:�2/+ Statistical arbitrage pairs trading / mean reversion / market neutral trading strategies based on cointegration / bollinger bands / kalman filter etc for commodities, stocks and Forex.

Filter trading strategy, ii. WKFPR, unlike the raw price relative that measures only how much the price moves from one period to the next, measures how far the price deviates from the inherent trend value. Whereas fear in Bear Market can be much more extreme and is more dangerous to trade using mean reversion. We discuss whether we should use price, log prices, or ratios to construct spreads.
