My point, anyone contemplating buy & hold of stocks, it's a lazy form of investment and laziness has it's price, basically a random outcome, may as well buy lottery tickets with the money you would otherwise spend on holding positions.
On the other hand, buy & hold with the simplest bit of homework (but that too would be difficult for a non financial literate person) and drop in maybe a loose weekly trailing stop would be better than nothing. One of the metrics I use is historical volatility, looking back over the last couple of years. If it has been too volatile, don't touch from an investment perspective. Unfortunately for them most lay investors are not able to get this information.
Understood, but you'd have buy a basket of Li miners.
