<prompt> Human: Going with the Warren Buffet line of be cautious when others are bold and be bold when others are cautious and looking at the sky high prices in the market, feels like at the very least should prepare for my Vanguard IRA and 401k portfolio to take a hit should the market drop like it did during 07-09. Have heard bonds are usually the typical hedge against market downturn as its fairly assured money, but halve also heard recently that some bonds are getting negative returns at this time. What are some other common places one can put their tax-deferred account money into to better weather a bad market?  <response>: Buffett would advise you not to try to time the market.
