Buy NVDA by Jan 6, 2029.

I want to invest for a down payment for a house. I had my emergency funds already saved in a hysa. This $2000 doesn’t include Roth IRA. This is purely what I can save. What stock should I invest in. I hope to get a good chunk of money in 3 years. Some stocks I am thinking about is Rblk Google Amazon Nvidia I also don’t want to be too heavy in tech.
