Some people (e.g. Bill Gross) think there's a bond bubble too. As bond prices and interest rates are inversely correlated, and it's hard for rates to go anywhere but up at the moment, imho they're probably right. I don't think anyone has a good handle on what asset classes are particularly safe (or, equivalently, will yield reasonable returns over the near-intermediate term) at the moment. My best guess is that P/E ratios are still fairly sane-ish, so my investments are in stocks atm. YMMV, I am not an investment adviser, etc.

A bubble? No. A bubble is more than just "asset prices are higher than they should be".

Take stocks or real estate. The price goes up. People see the price going up. They buy, because they want to buy something where the price is going up so that they will make money. That buying increases demand without increasing supply, so the price goes up some more. That's a bubble - where the price goes up because people are buying because the price is going up (and so they think it's going to keep going up). It's a positive feedback loop.

But bonds... nobody's buying bonds because they think the price is going to go up. They're buying bonds because they think bonds are safe. But, in fact, bonds aren't very safe. The next direction interest rates will move is up; when they do, bond prices will fall. The longer term the bonds, the more the price will fall.

Note well: I am not an economist. I am not an investment advisor. This is my understanding of how things work, but it is not financial advice.

"Rates don't have anywhere to go but up" is an argument I've seen used often but it doesn't hold water. First, the 10yr is at 2.25% right now, and nominal yields have hit negative in other countries, so we could go there. Or, rates could just churn for a decade. Both of these are completely plausible scenarios.
