Exchange traded funds, or ETFs for short, are essentially funds that trade just like individual stocks. As these instruments have become very popular among traders, more and more crypto & forex brokers have also started offering them for trading as highly leveraged CFDs.
A great advantage of trading ETFs is that they can offer a trader exposure to a whole group of stocks or commodities by just taking a single position in the ETF. This means that it becomes easy to take a bet on the direction of a certain industry, or on the stock market as a whole, without having to buy each individual stock. When traded as CFDs, it also becomes much easier to short these instruments than what would be possible in the traditional stock market.
