Bonds don’t play the same game as stocks. Bonds are your trust in the government, not in business. Thus up and down cycles in bond markets are different than these cycles in stock markets.

different but not inversely correlated. Its suboptimal versus true hedge. also see inflation adjusted returns on bonds .

Yes, bonds have lower returns and bonds alone are a bad investment. Everyone knows that. But bonds tend to grow rapidly during financial troubles thus dampening negative effects of stock market failures (because central banks tend to increase rates to combat inflation).

Central banks increasing rates lowers value of prior issued bonds. and bonds growing in financial crisis is just a noncausal correlation thats not a fixed way things work. In the macroeconomic position we are entering it doesn't make sense . Look at how TLT was down like 30+% during this crash that just happened in stock and bonds .

I understand what you are saying about diversification but it makes no sense to put money in bonds when you can have other hedges that have true mechanistic inverse correlation and bonds are negative real yield. Show me any diversification set up using bonds and i can show you a higher yielding setup that has lower risk.

They tend to know this stuff better than you and they bear legal responsibility

definitely they don't. Most of those people are idiot parasites stealing from financially illiterate people.
