in pieces (not all on one day, spread it out over a couple months)

I would stay away from bonds as they will plummet with a rise in interest rates.
If you want to wait, go into short CD's for 50% of your $50K until the "CORRECTION" and you will be positioned to step in and get a bit more for your money
William - - The answer really depends on how the rest of your financial life looks. And your age.
Generally speaking, a retiree should have at least 12 months of expenses invested in "cash or cash equivalents". Note that this is in ADDITION to your emergency savings account.
If you have a plan already in place for your existing retirement savings, then this 50K should be invested in the same way, with the same asst allocation. If this $50K is a windfall, then you can probably revisit your plan and give yourself a raise - - - the size of which will depend on your age.
Sorry I can't be more help, but the answer as to what you should do with the money will differ substantially depending on your age, health, other savings, debt, other income, and goals.
By "retiree" you mean you've already retired? Or planning to retire?
Either way it's your retirement planning and, unless you can afford to lose this 50k, you should put it somewhere that won't lose value.
Shares can collapse in value at ANY time.
