Definition of Market timing
Market timing  is the action of moving in and out of the marketplace or switching between asset classes based on using predictive methods for example technical signs or economic data.
Brief Explanation of Market timing
Because it is extremely hard to estimate the future direction of trading stocks, traders who try to time the marketplace, especially common finance traders, tend to underperform traders who remain spent.
Therefore, whether the Market timing is possible is really a matter of opinion. Some traders, especially instructors, believe it doesn’t seem possible to time the marketplace. Other traders, especially active traders, believe strongly in Market timing. For the average trader who does not have time, or desire, to watch the marketplace on an everyday basis, there are why you should avoid Market timing and focus on investing for a lengthy term. What can be said with confidence is it is very challenging to successfully time the marketplace continually over the lengthy term. In the evaluation of Morningstar, actively handled domain portfolios that moved in and out of the marketplace between 2004 and 2014 came back 1.5% less than passively handled domain portfolios. Market timing is possible to do. Few traders have been able to estimate market changes with such reliability that they gain any big benefit over the buy-and-hold crowd.
