I thought I was crazy to buy AAPL $Apple(AAPL.US)$ at its valuation. But it seems the flight to safety stocks dont seem to have people caring about valuations they just keep going up. Others include MSFT $Microsoft(MSFT.US)$ , GOOG $Alphabet-C(GOOG.US)$ , and UNH $UnitedHealth(UNH.US)$ . They hold up the indexes and hide the bear market going on in so many stocks.
