Investors want safety now. But how should they go about finding it?

The yield on the 30-year U.S. bond rose to 2.563% on June 23 as citizens of the United Kingdom were voting to stay or leave the European Union. Odds of staying were good, so when the "leave" vote beat the "stay" vote by four percentage points, the bond yield declined to a 52-week low of 2.280% overnight. That nearly tested my downside target for 2016 of 2.265%. This week's pivot is 2.374%.

Comex gold futures were equally volatile. As the "Brexit" votes were being counted, gold traded as low as $1,252.8 the Troy ounce. When the "leave" vote won the referendum, gold traded to a 52-week high of $1,362.6. My upside target for 2016 is $1,639.9, as long as weekly closes are above its 200-week simple moving average of $1,310.6. Note that the gold ETF did not end last week above its 200-week simple moving average.

The Dow utility average did not trade in the overnight period of the Brexit vote. It opened lower on June 24 in sympathy with the major equity averages. As investors poured money into dividend-paying stocks like utilities, the average set an all-time high of 691.93 during the trading session. This week's pivot is 688.22.

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 an exchange-traded fund 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. Treasuries should consider the SPDR Barclays High Yield Bond ETF (JNK - Get Report) . Keep in mind that the performance of junk bonds correlates to the stock market, not to the bond market.

The S&P 500 SPDR ETF (SPY - Get Report) has a year-to-date loss of 0.3%, while the U.S. Treasury bond ETF, the gold ETF and the utility stocks ETF have year-to-date gains of 12.6%, 24.2% and 16.5%, respectively, as "flight to safety" investment strategies continue to outperform "risk on" equity investment strategies.

The bond ETF has a positive weekly chart, with the ETF above its key weekly moving average of $133.06 and well above its 200-week simple moving average of $118.82, last tested in July 2015. The weekly momentum reading ended last week at 78.38, up from 74.64 on June 17.

Investors looking to buy the bond ETF should do so on weakness to $132.45, which was tested on June 23. This key level remains in play for the remainder of 2016.

Investors looking to buy the gold ETF should do so on weakness to $121.18, which is a key level on technical charts until the end of June.

The utilities ETF has a positive but overbought weekly chart, with the ETF above its key weekly moving average of $49.67 and well above its 200-week simple moving average of $41.81. The weekly momentum reading rose to 85.96 last week, up from 82.92 on June 17.

Investors looking to buy the utilities ETF should do so on weakness to $48.60, which is a key level on technical charts until the end of June.

Investors looking to reduce holdings should continue to do so above $50.15, which is a key level on technical charts until the end of June. This call is based upon a meager dividend yield of 2.90%.

Here's the weekly chart for the junk bond ETF.

The weekly chart for the junk bond ETF has been downgraded to neutral from positive but overbought, with the ETF above its key weekly moving average of $34.96. The ETF is well below its 200-week simple moving average of $39, reflecting the popping of the junk bond bubble. The weekly momentum reading ended last week at 78.44, down from 82.34 on June 17. A weekly close below $34.96 will shift the weekly chart to negative.

Investors looking to buy the junk bond ETF should do so on weakness to $33.40, which is a key level on technical charts until the end of June.

Investors looking to reduce holdings should do so on strength to $37.53, which is a key level on technical charts until the end of June.
