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