If you are looking for a safe haven then you truly have to define what you mean by safe haven. Safe can mean liquidity, stability, inflation protection, etc.... Those things can be independent of each other.
I feel a better approach to investing is that each and every investment you have must have a compelling reason to be in your portfolio. Whether it is any that I mentioned or say dividends for example. If the compelling reason you own an investment is for rising dividends then ask yourself in times of turmoil "Has the compelling reason changed?" If not, don't sell and maybe consider adding to the position.
If it has changed then you must figure out a way to unwind the position if it is not at a point of fortunate liquidation. You can bet that every investment that you own (or just about) will have a time of turmoil and these gut checks are important.
YMMV.
