Why Most Investors Are Leaving AI’s Full Potential on the Table

How to use structured AI prompts to get-scary good results with 5 real world examples

If you throw basic questions at ChatGPT and wonder why you get some generic output back, you’re not alone, most investors are using AI for research the wrong way.

But, the secret isn't which Large Language Model (LLM) you use, it's how you talk to it.

Why Prompt Structure Actually Matters

Think of it like this: You wouldn't walk up to a Wall Street analyst and just say "tell me about Apple stock," right? You'd give them specific instructions, timeframes, and exactly what kind of analysis you need.

Same principle applies to AI. Structure your prompts properly, by putting examples in <example> tags, instructions in <instruction> tags and so on, it helps the AI understand the role of the various types of information you're giving it.

Ok, let’s run a quick comparison.

Basic Prompt: "Tell me about Apple stock"

Structured Prompt with XML Tags:

<role>Act as a senior equity analyst</role>
<task>Analyze Apple Inc. (AAPL) stock</task>
<format>
- Executive summary (2-3 sentences)
- Key financial metrics
- Competitive position
- Risk factors
- Investment thesis
</format>
<constraints>Focus on Q1 and Q2 2025 data, be objective, highlight both positives and negatives</constraints>

Output:

See the difference? The structured version gives you organized, actionable and predictable outputs instead of generic information dumps.

So, let’s see some real world examples.

Conclusion

AI won't replace your entire stock research process (at least not now), but it'll make your research faster and more systematic.

Start Simple, and pick one prompt and test it with a stock you know well. See how the analysis compares to your own research.

And, please don’t forget to verify EVERYTHING. AI is brilliant for structure and ideas, but always fact-check the numbers and claims against official sources.
