PTTRX is a Bond fund. A bond fund's share price goes up when interest rate comes down. PTTRX this year performs extremely well because interest rate low low low, share price up up up. I just checked its historical prices at Yahoo Finance, since 2000 its price has ever reached 11.70 range was Nov. 2010 . Usually people put their money in a Bond fund is when interest rate is high and share price is low. If economy improved, interest rate likely to rise and price will drop. The yield provides some cushion but sometimes not enough to make up the loss caused by price drop. I feel PTTRX share price at 11.60's is almost at its peak now, I'd rather wait.
