After four months of trading, "risk-off" investment strategies like gold, bonds and utilities stocks continue to outperform "risk-on" stock market investments significantly. On Monday, Comex gold traded above $1,300 the Troy ounce for the first time since January 2015.

Here's how to trade lower-risk assets as they rise.

The U.S. Treasury bond exchange-traded fund, the gold ETF and the utility stocks ETF now have year-to-date gains of 7.3%, 21.9% and 11.9%, respectively, vs. 6.6%, 16.2% and 9.4% a week ago, led by a new 2016 high for gold.

The S&P 500 SPDR ETF (SPY) - Get Report now has a year-to-date gain of just 1.2%, down from 2.5% a week ago, as "flight to safety" investments outperform stock market investments.

Be careful with the junk bond ETF, as it correlates better to the stock market than to the U.S. treasury bond. The junk bond ETF now has a gain of 4.1% year to date, up from 3.3% last week.

Investors can trade the U.S. Treasury 30-year bond like a stock using the 20+ Year Treasury Bond ETF(TLT) - Get Report , which is  backed by a basket of U.S. Treasury bonds with maturities of 20 years to 30 years.

Investors can trade gold like a stock using the SPDR Gold Shares ETF (GLD) - Get Report , which is backed by gold bullion.

Investors seeking the safety of dividends can trade the Utilities Select Sector SPDR Fund (XLU) - Get Report , which is a basket of 29 utility stocks.

Investors betting that junk bond yields will tighten against U.S. Treasury securities should consider the SPDR Barclays High Yield Bond ETF (JNK) - Get Report .
