Hi everyone,

I’m a new investor and I’m looking for advice on building my first serious stock portfolio.

I currently have around $20,000 available to invest and I’m planning to hold for the long term (5–10+ years).

My goal is not to get rich quickly. I want to build a portfolio that can grow over time while learning how experienced investors think.

Right now, I’m considering a mix of:

• Broad market ETFs
• Large, established companies
• A few individual stocks I believe have strong long term potential

Some companies and sectors I’ve been researching:

• Technology and AI
• Semiconductors
• Cloud computing
• Healthcare
• Financial companies

But I’m still unsure about the right approach.

Some questions I have:

1. If you had $20,000 as a beginner investor, how would you allocate it?
2. Would you invest everything at once or use dollar cost averaging?
3. How many individual stocks are reasonable for a beginner portfolio?
4. Would you focus mostly on ETFs or pick individual companies?
5. What mistakes did you make when you first started investing?
6. What metrics should a beginner learn first when evaluating a company?

I’m especially interested in hearing both sides:

Bull case: What opportunities should a new investor pay attention to?

Bear case: What risks or common mistakes should beginners avoid?

I’m not looking for financial advice or a guaranteed winner. I’m trying to learn how experienced investors approach building wealth.

Thanks for sharing your experience!
