Subject: Re: is there a lot of risk in Treasury bills now?
Also, it is not in stone. If I am not mistaken the Tips are liquid, I could buy more or sell more as time goes bye, getting a profit or taking a loss.
Am I correct about this?

Sure. The prices of TIPS don't gyrate nearly as much as many other things, but they can certainly be traded.

The main "timing" thing is it is good to buy them at a good initial yield if you can : )
This is a chart of the last decade of ten-year TIPS yields. https://fred.stlouisfed.org/se...
You can see that they are currently near the highest in that length of time. That's perhaps a bad omen for the US economy and currency--people are shunning US bonds and even an inflation guarantee isn't tempting them much--but good for a TIPS buyer.

Avoid TIPS funds. Yields are low, so paying a management fee is a significant hit, and you don't get to pick your maturity.
