Don't Let Emotions Ruin Your ETF Portfolio | Page 2 of 2 | ETF Trends

While investors can try to play the guessing game in an attempt to time market bottoms, investors can stick to a by-and-hold or systematic investing strategy where buy and sell executions are based on individual needs, not on short-term events.

“No matter how much people have been educated that past performance is no guarantee of future results, they want to buy what’s been hot and they expect it to stay that way,” Lou Harvey, DALBAR’s president, said in the article. “But even if you say it’s human nature to buy funds at the wrong time, you can still go off and buy good funds — ones where there is a higher probability of the future delivering good results like the past — and then getting the performance of those funds from the moment you buy them forward,”

At ETF Trends, we like to follow the trends to help guide us through our investments. For instance, we take the long-term, 200-day exponential moving average to help us determine when we are in or out of a position. If the ETF crosses over the 200-day EMA, it is a buy signal, and if the fund dips below its long-term trend, it may be time to let go. This simple trend following strategy limits primal fight-or-flight emotions that can seep into your investment decisions. [An ETF Trend-Following Plan for All Seasons]
