Kenneth Fisher thinks we’re still in the middle of a bull market, and that most investors are thinking too myopically — and don’t understand quantitative easing at all. Fisher tells Bloomberg that the bull market hasn’t yet transitioned into the “optimism” stage that signals the final stage of a bull run. In fact, he says the notion that we’re in the middle part of a bull market is a “really impossible concept for most people to get” given all the worries and pessimism out there. Fisher says most people haven’t come to grips with the idea that the 2008-09 financial crisis was likely a once-in-a-lifetime event, and instead are allowing their fears of the past to dictate their actions.
