Not denying the mid- to long-term outlook is positive, but if anyone tried to trade in the last week or so they would have been stopped out by the enormous whipsaws up and down.
Buy and hold, if you have a perma-bullish outlook? (Or even just if you understand the nature of capitalism and stock markets with their permanent REQUIREMENT for continuous growth to survive)
As per Daniel Kahneman in 'Thinking Fast/Slow', stop looking at charts every day and only readjust your 'portfolio' every few months?
Stop getting whipsawed by this 'volatility' that 'day traders' talk about, but for most people just results in being stopped out?
