If you have a portfolio of stocks, it’s a good question. How often should you check on them? Once a quarter, once a month, once a day, once an hour?
Most of that answer to that question has to do with your personality. If you can check on the pricing of your stocks every day and not be tempted to sell because one of them went up 5%, fine. But if that is going to entice you to trade in and out of your stocks, then checking less frequently might make sense.
Remember that stocks are long term investments. If you owned a business, you wouldn’t call up a business broker and get a quote for your business every day, nor would you sell just because you were offered 5% more than yesterday. It’s the long term that counts.
Yeah, you could miss the absolute bottom or top on a stock by not looking every day. But in the long run that won’t count as much as buying stocks when they are cheap and selling them when they are expensive. And that doesn’t happen in a day.
