Wind in our sails can push us higher but it's the water that keeps us afloat. A PR is a breath of air but doesn't have staying power. This is why investors often find themselves disappointed.
Many of us have averaged down enough to enable us to trade out of some of our shares when we find we're well ahead. I call these "trading" shares. Then there are the "core" shares which we hold indefinitely. It's important to think in terms of core and trading as it provides you with opportunity to take profits along the way while preserving the longer term expectations.
