History will tell you being fully invested is profitable. Trying to time the markets is nigh on impossible, trying to figure out the macro events IS impossible. Find a couple of good stocks, stick with them and watch the business like a hawk and don't worry about the share price. The long term trend of the business and the quality of management is easier to assess and is far better for your health than reacting to the ups and downs of the share price or reacting to the daily negative news! (which turn out to be BS anyway).
