Investments in stock markets are quite risky. It is not easy to predict the performance of stocks easily. Some stocks perform well in a market crash. One factor determining the next market crash is when prices are high for a prolonged period. One should implement his/her investment strategies accordingly. Some other factors include rising inflation, a high price-earnings ratio, weak economic indicators, high market expectations, and declining sales should also be considered by the investors. Some unfortunate events such as terrorist attacks and the pandemic also result in market declines.
