Super, what does this comment refer to?
You CAN put your money into a savings-type account to "park" it. That may not be your best or safest option, but you can do it. I don't understand the meaning of your comment above saying that you can't. I have put money into savings-type accounts for short term parking between investment changes in the past.
With a savings account, you're not going to earn much interest to increase your money, but not not going to lose money in the stock market either. You could lose the money if the bank failed, which is what FDIC insurance covers. So you want to choose a bank that has FDIC insurance (if the bank has it, it's automatic and free - you don't have to sign up for it or anything). Of course, if things are so bad that not only the bank fails, but the US government starts failing to pay on debts too, then FDIC insurance is not going to be all that useful (since it's a government thing).
If someone WAS going to park money in a savings account, remember that the FDIC insurance only covers loss due to a bank failure up to a max of $250,000 in your account. There are a couple of ways you can increase that however. The easiest is probably to add a few beneficiaries. e.g., if you own the account, you're covered up to $250,000. If you add a single "payable on death" beneficiary (and you SHOULD have beneficiaries specifically listed if you're talking about 1/4 million dollar+ accounts), then the money in your account is insured up to $500,000. Add another beneficiary, so you now have two, and the insurance goes up to $750,000. There is a limit as to how many beneficiaries you can use to increase the insurance amount, but I forget what that number is at the moment. I think you can get up to at least a million in insurance, if not more, using the beneficiary technique. I do not recall if you can list a trust as your beneficiary or if that increases the FDIC coverage like a human beneficiary does. I think you can do that, but I just can't remember to tell you the truth.
