The instinct is to panic. And sell. Or buy what seems now under-valued. Wrong, at least for Baby Boomers who are not investment experts.
Before doing anything, speak with those financial experts who will give you a complimentary consultation. Realize their take is only their opinion. No one knows for certain what will happen, how or when.
Also, read the business media.
Unlike Millennials and even members of Generation X, most Baby Boomers don't have the time left or the earning power to make themselves whole after gigantic losses.
