Long bonds flying on Operation Twist - $ZB_F $TLT

Earlier this afternoon on Twitter, I noted that the long bond ETF, TLT was up over 10% (then quoted near $114.60) since S&P downgraded the USA's debt rating to AA+ on August 5, 2011.

Well, it looks like we'll have to update those stats already, thanks to the pop in 30 year bonds (ZB_F) and in TLT on news of Operation Twist, the Fed's telegraphed scheme to sell $400bn of short maturity bonds and reinvest in longer (6 to 30 year) bonds by June 2012. 

Here's how the market reacted to that news. Note the flagpole move up in TLT and the 30 year Treasury futures, ZB_F on the intraday charts.

So in the space of 20 minutes, we had to recalculate that 6 week return figure (post S&P debt downgrade): the long bond ETF TLT is now up 13% since its close on August 5th, based on an intraday price of $117.70

What a difference a day makes... Any source
