Quantitative easing is an expansionary policy where instead of buying short term securities in the market, the central bank (Fed) buys longer term securities. This will put more money into the economy as well as reduce interest rates due to the increased demand for the securities that the central bank creates.
With an increased supply of dollars relative to demand in the economy, the value of dollars will fall in value.
This is good for a U.S. based company as their goods will now become cheaper as they are denominated in dollars. As their goods ae cheaper, they will sell more goods abroad.
