One of them is that there are always young technology companies that are always expanding and growing. Examples include Amazon and Apple. Another trend is investing in stocks, in which these companies peak at a certain time of the year. An example is when I bought Hershey (HSY). I bought it at the end of January, a few weeks before Valentine's Day, hoping the price would increase since chocolate is a common Valentine's Day gift. Another trend is that many companies do not pay dividends to their shareholders. For example, Boston Scientific (BSX) currently does not pay any dividends. A final trend is that alternative energy stocks are becoming increasingly popular. For example, the stock prices of Tesla Motors (TSLA) and Xcel Energy (XEL) have increased significantly in recent years.
