Bear market is bad to those who have bought at a much higher price. That is true. Especially to those who have already emptied their savings and investment funds only to find out after a month or two that the prices are plunging deep. That is painful! I have been there. And especially if there will be long days, weeks, and months, and even a year more to wait for the buying price to return.
Ouch. Getting burnt like that has to hurt.
Diversify. Diversify. Diversify.
It can be a boring strategy, but it is the best strategy for most people.
