The economy has changed. We're going to be facing more volatility in the job arena. That can wipe you out in a heartbeat.
This type of concentration means you have to be an excellent stock picker, something that many professionals wouldn't try.
One rule of thumb to keep in mind is that any monies for short-term goals such as this home purchase should not be invested in the stock market. Market volatility could present problems if you do not have a longer time horizon for such investments.
The first tenet is an emergency fund. Even before you save for retirement that needs to be put in place.
I like to call it paying yourself first. It means putting yourself as a priority.
I don't care when you retire. Your money can never retire.
That was a thing we were getting away from when the equity markets were on a tear. Everybody thought you were a fool to get into anything else.
