The simplest way to benefit from a rising market is to buy an index fund. When you buy individual stocks, you can make higher profits, but you also face the risk of under-performance. Unfortunately the Dropbox, Inc. ( NASDAQ:DBX ) share price slid 28% over twelve months. That falls noticeably short of the market decline of around 14%. The silver lining (for longer term investors) is that the stock is still 13% higher than it was three years ago. Unfortunately the share price momentum is still quite negative, with prices down 8.4% in thirty days.
