There’s one major question I often see. It’s the question of WHEN. When will the market crash? When will a recession occur? There’s no possible way to determine exactly but we have indicators to watch that will help guide us in the right direction. From that point we can always make better judgements. But without the knowledge, we are unable to be prepared and that’s foolish.
