Trend following strategies attempt to take advantage of long-term market moves by following price trends without considering past performance. The strategies rely on the assumptions that price trends regularly occur and markets fluctuate up and down over time. Technical trading can predict or react to trends, while trend following simply follows established trends without emotional involvement. Common trend following methods include lookback straddles, generating anticipatory scenarios through time series analysis, stochastic optimization algorithms, and static portfolio models that use a buy-and-hold strategy.
