Gold endured its worst one-day performance of 2014 as futures and bullion-backed exchange traded funds were hit with some profit-taking.

The SPDR Gold Shares (NYSEArca: GLD) lost 2.3% on volume that was 64% above the daily average as investors scurried into U.S. stocks and other riskier assets on talk of light physical demand and speculation that Portugal’s banking system is not as bad as off as investors were thinking last week.

“Some prudent diversification into safer assets has been the early second-half trend, with geopolitical risks escalating in the Middle East and Russia, economic risks increasing in Europe and volatility returning to equity markets. Gold and silver were the best performing precious metals last week,” according to a new research note from ETF Securities.

Even with Monday’s drubbing, GLD is up more than 5% since the start of June. Entering Monday, the world’s largest gold ETF, had added nearly $408 million in new assets just this month. [These ETFs are Gaining Assets in July]

Still, some traders view an uptick in broader market volatility as important to further near-term upside for gold and silver.

In late May, ETF Securities noted silver volatility was hovering around multi-year lows.

“History indicates the recent decline in silver price volatility to the lowest levels in over a decade(at the beginning of May), as measured by 30-day volatility, may be a precursor to a strong price move. In our view, downside risk is limited with industrial demand picking up and supply in decline. With the silver price less than half its 2011 peak and futures shorts already elevated, we believe the next strong trend price move is likely to be up,” ETF Securities said at the time.

Since May 30, the iShares Silver Trust (NYSEArca: SLV) and the ETFS Physical Silver Shares (NYSEArca: SIVR) are up about 12%.
