PTTRX performs extremely well this year, because interest rate so low hence its share price kept going up. Since 2000 it ever reached 11.70 level was Nov. 2010 for a few days only. I'm afraid the price is too close to its peak now. No one has a crystal ball, but for long term investment, people invest in a Bond fund when interest rate rises and share price drops. The 3.7% yield sometimes is not enough to make up for the loss caused by price drops. Just my humble opinion.
