OK.
People here generally believe in staying in the market, and that trying to predict its movement is futile. They use asset allocation (AA), and would rebalance between stocks and bonds when their AA is out of whack. In other words, they believe that it is not productive to make market calls, and would simply wait to respond to market movements after the fact.
The above people call those who try to "time the market" DMT, short for dirty market timers.
I am among the people who know that it is tough but not wanting to give up this Quixotic effort, still try to predict the market a little but rely on macroeconomic and political information instead of just the stock charts or "technical analysis". I jokingly call myself "Clean Market Timer" because I do not consider myself dirty.
Search for CMT if you are curious to see how it started.
PS. I do consider the "chartists" DMT.
