I’m usually too geeky to hype any investment as being best or worst of anything. Sometimes, though, even I have to get down, get dirty and use the S-word: Sell. I do that today with the iShares 20+ Year Treasury ETF ($TLT) and the PIMCO 25 Year Zero-Coupon US Treasury Index ETF ($ZROZ) and 12 similar monstrosities.
