CoinWorld reports that Mike McGlone, senior market analyst at Bloomberg Intelligence, stated in his April metals market outlook report that gold is facing a difficult barrier caused by overly extended speculative activity at the beginning of the year. The peak in January may represent a once-in-a-lifetime historical high. He noted that as speculative momentum shifts this yellow metal from a safe-haven asset to a risk asset, gold is still struggling. He pointed out that the 180-day volatility of gold is more than twice that of the S&P 500 index and is at its highest quarterly level since 2006. Similarly, silver's rally to $120 per ounce in January may also indicate a historic peak. (Kitco)
