I was looking at my retirement fund a few months ago. A T. Rowe Price long treasury fund showed a 28% return for last year. I thought it might repeat based on what the FED is doing. Put 100k in it. Was up as much as 4k since Sept when I set it up. It has drifted down to about 2600 since the market went green but still solid.

Any experience and opinions on such things?
