At the risk of over-simplification, an MR trader taking a view that an asset was over-priced and therefore had a higher probability of reverting to the mean than any other development, would trade it short to around the point where it met the new mean value (or beyond allowing for over-shoot if they were somewhat more aggressive). MR traders normally do have an underlying trend bias in that the mean is rarely flat and they will typically only trade the contra underlying leg. In this example, the underlying (the mean) is downward and they’ll trade the short from above the mean, but less likely to trade Long from beneath.well following on from my post above, lets say that the two traders we're comparing:
Mean Reversioner makes decisions on 80% order flow 20% information
Trend Follower makes decisions on 20% order flow 80% information
so in their ratio's they are equal but opposite. they will deffo be trading at different frequencies.
A Trend trader will (normally) be found trading only on the ‘correct’ side of the mean and in this example of a downward trending asset will likely be setting up for his entry as the MR chappie is preparing to exit his.
Even in an idealised scenario with an aggressive MR trader that will take both legs of price deviation from the mean, he’s still only going to take a maximum of two trades to our trending guy’s one. That is a significant enough basis for assessing potential longevity of the two types of trade and trader, but as stated, that is an idealised situation which is unlikely to hold in reality.
My view is that the MR trader may push a few more trades through than your typical trend player, but not a statistically significant number.
