Bonds are perfectly safe investments when the normal consideration of safety is that you cannot lose money and you know your exact return through maturity. Can you miss out on better investments, ofcourse. The only issue is investing someone else's money into bonds - because they are the ones to decide when the cash is needed, not you. But I'd be shocked if at any given time at least 90% of cash is not invested in someway. You only want to keep what you need immediately out of investments.
