Stock price when the opinion was issued
With this one, you are making a bet that US long bonds are going to decline. If you think interest rates are going up and bond prices are going to come down, this is a way to play it on a short-term basis and get 2 to 1 leverage. Every time you deal with a leveraged ETF, recognize that what they are doing is rolling over a series of futures contracts and there is a cost to doing that. That cost is implicit in the value of the product.
This is the ultra-short long treasuries, which is basically a levered product. With this one you are betting against the Fed which recently announced they are going to be buying 10-30 year bonds until the economy improves. You will have a buyer against you for a long time, however if the economy succeeds, the yield should increase. You have the time against you so you have to be careful. Wait until you see growth rates really pick up in manufacturing, consumers and housing.
This is a bet against bonds and a bet that interest rates are going up. It is also a great portfolio hedge especially with portfolios that have a high percentage of equities. There has been a long term decline in bond yields but a reversal is starting. However this doesn't mean that a return to previous highs is coming. It is a good time to buy now with minimal risk but be temperate in your position.
