It's often advised to buy and keep government bond to protect ourselves against the next upcoming crisis. (For example, in a defensive stock portfolio you can have 50% of stock and maybe 30% of government bond and 20% of gold/silver.)
But I couldn't find historic data on how the US 10 year treasury bond behaved on 2008 crisis. In TradingView you can go back to up to March 2014 and that's all! But we still can see what US10 did on stock drop at the end of 2018. But the value went only from 97 to 103 (from 5th November to 31st December). This is 6% decrease. In the same period, SPX went down from 2774 to 2400 which is a 13% increase.
Is there anything that perform better than the U.S. 10 year treasury bond in case of crisis ? (No, I don't want to short anything. Too much risk.)
