Retail investors are getting into the idea of passive investing and we’ve seen a steady increase in the funds poured into ETFs. A top choice for investors, Vanguard has set a gold standard for low-cost funds that are ideal for long-term investors.

The oldest exchange-traded fund listed in the U.S. has just been surpassed in assets under management by a Vanguard ETF that more cheaply tracks the S&P 500 index.

With Vanguard taking the top place among the ETF providers, it is now time to consider two of its ETFs with over 10% upside potential in the next 12 months. These include Vanguard Communication Services ETF (VOX) and Vanguard Dividend Appreciation ETF (VIG).
