It has never occurred to me to be bothered by short-term price swings even if they are significant. The secret to these things is to sit down and review the fundamentals every six months or so. If something has changed, why then you may need to sell. Otherwise, what does really matter what the market price is?

There are some people who think that they have mechanisms to figure out what is going to happen in the next month, next day, or next hour. This is wackoism. On a day-to-day basis, optimal investment results are achieved by ignoring market fluctuations and spending you time on something more worthwhile
