How to invest?

It is evident that people migrate their assets to which gives good yields. Those who holds position in stocks at the time of bull run consider themselves as long term investors. But that won't last longer. Whenever the fed comes up with good bond yield followed by the inflation, these long term investors becomes short term investors and sell all their positions to build new positions in government bonds. This is swing. Wherever they see big number, they switch. But this is not how an actual investor do. He invests and stands still, may be even for decades. At the end of his tenure, we call him successful and study him. But the only thing that we see different there is a simple factor of patience. He never swings with the news, but stick with the guts.
