Investors can trade the U.S. Treasury 30-Year Bond like a stock using the 20+ Year Treasury Bond ETF, which is backed by a basket of U.S. Treasury bonds with maturities of 20 years to 30 years. As a stock-type investment it never matures and interest income is converted to periodic dividend payments. Here's the weekly chart for the bond ETF.

The weekly chart for the bond ETF remains negative but oversold, with the ETF below its key weekly moving average of $120.72 and below its 200-week simple moving average of $120.27. That is the "reversion to the mean," which has been a magnet since the week of Nov. 18. The weekly momentum reading rose to 18.49 last week, up from 16.55 on Jan. 20. Despite the hype that yields are destined to rise, a close this week above $120.72 with momentum rising above 20.00 would signal that bond yields are headed lower.

Investors looking to buy the bond ETF should consider buying weakness to $117.73, $115.92 and $105.77, which are key levels on technical charts until the end of this week, until the end of June and until the end of 2017, respectively. Investors looking to reduce holdings should do so on strength to $126.87, which is a key level until the end of March.

Investors can trade gold like a stock using the SPDR Gold Shares ETF, which is backed by gold bullion.

The weekly momentum reading rose to 29.08 last week, up from 23.06 on Jan. 20, moving above the oversold threshold of 20.00 for the first time since the week of Nov. 18.

A semiannual risky level is $54.29.

The SPDR Barclays High Yield Bond ETF is for investors betting that junk bond yields will tighten against U.S. Treasury securities. Remember that the performance of junk bonds correlates more to the stock market, not to the bond market, hence the recent tightening of spreads.

The weekly momentum reading rose to 86.55 last week, up from 82.09 on Jan. 20, moving further above the overbought threshold of 80.00.
