why the price of gold is going high?

Answer 1

If you measure the price of gold in dollars, the price is going up. It could be because gold is becoming more valuable or also that the value of the U.S. dollar is down. Gold priced in euros or yen has not gone up as much. In general, we can say that the value of the dollar has gone down.

Answer 2

Gold and other precious metals are inflation hedges and since inflation remains a concern especially with the market probably in a bubble stage this is one of the preferred moves for conservative investors. Real estate is on a nice big downward spiral so people have to put their money somewhere and demand drives the price of gold.
