Re: F Fund for a deflation trade.
Okay, those looking to play with F as a longer term hold towards a 'deflating' economy, be weary. Reason being, the average bond duration for Aggregate Bond Index is only around 6.2 years. The low end durations (<10 years) have been manipulated by the Fed's artificially low interest rate and really don't have any upside left. (Basically, the Fed buys the short end to keep rates low.) The high end bonds (30 year treasury) have been flying off the handle because that is where the buying interest has been amongst institutions. Usually a 30 year is yielding at least high 4% (or 5%), whereas today it yields 3.69!
We shall see whether the rejection on Friday was a reversal of the deflation trade or 'profit taking'

at resistance.
I'm personally out of treasuries for the deflation trade as I closed out positions last Wednesday. I do, however, have some exposure as part of a diversified LT indexed portfolio.
