Unless your dealing with leveraged investments, day to day swings mean very little.  Occasionally the market has a huge drop, but right after a big drop tends to be the best times to invest in the stock market.  However, mentally people feel the need to double down when it&#x27;s up and take money out when it&#x27;s down which can quickly destroy decades of growth.<p>PS: If you can see a 60% drop and think, yay! great time to invest then feel free.  Otherwise, checking once a year is probably fine.
