Investing in the forex market helps investors diversify and hedge with currencies, which may help reduce risk while maintaining an upside potential. For instance, individuals holding assets denominated in a foreign currency are exposed to currency risks – if the foreign currency weakens compared to the U.S. dollar, the investor’s foreign investments will also depreciate in value once converted back to U.S. dollars.

Unlike the stock market, currencies usually oscillate between a support and resistance level over the long-term. Inflation and monetary policy, for example, prevent currencies from increasing in value indefinitely. As one currency gains value, another has to depreciate to balance the effect out.
