A lot depends on you age. My first thought would be to put it in a Roth IRA. That way every penny you make on the investment will be tax free and you can invest it anyway you like. Can't withdraw until 591/2 or add to after 701/2. No RMD and doesn't add to medicare income limit.
That's fine if you are willing to take the current period tax hit on converting from traditional to a ROTH. It's not just float 100% to a ROTH and now it becomes tax free on witrhdrawl.
