CIT Bank has a 5.0% APY savings account as long as you put at least $5k in. No reason to do a CD or put money in stocks when your time horizon is so short and the rates on HYSAs are so favorable.
The only small catch is that HYSA interest rates are variable and could potentially decline compared to a CD with a locked in rate over the same time frame. But for only a few grand invested, either option is a ‘good’ choice.
