The S&P 500 is at an all-time high, but you should stay invested

RETAIL investors are known to make the classic mistake of buying high and selling low.

Because many investors are followers of trends, they may jump on the bandwagon when it has run its course and be left with nothing but losses.

As a result, there is another class of investors who are far more conservative and have learnt a contrary lesson: stay away from hot markets. However, this is also not rational.
