Human: What stocks should I buy to diversify my portfolio? Assistant: 
It depends on your individual financial situation and the risk profile you are willing to take. A well-diversified portfolio should include stocks from different sectors, such as healthcare, technology, energy, manufacturing, and finance. You should also consider buying stocks from different size companies, such as large-cap, mid-cap, and small-cap stocks. Additionally, you could also look into investing in international stocks in order to further diversify your portfolio.
