🦙 Real-Time Stock Analyzer | Powered by Dappier and LlamaIndex

This notebook demonstrates how to build a real-time, LLM-powered stock analysis assistant by combining LlamaIndex with Dappier. It walks through building an “Explain This Ticker” app that gives real-time explanations for stock movements, technicals, and valuation. In this notebook, you’ll explore:

Dappier: A platform that connects LLMs and agentic AI agents to real-time, rights-cleared data from trusted sources. It delivers verified, prompt-ready information across domains like web search, finance, news, and more.
LlamaIndex: A data framework that allows seamless integration of external tools with LLMs. It enables structured workflows for tool use, reasoning, and response generation.
OpenAI: An advanced AI model provider used here to power the assistant’s reasoning, planning, and response generation.

This setup offers a practical example of building context-aware applications with real-time data access. It can be easily extended to other domains requiring live insights and AI-driven decision-making.

Installation

To get started with the stock analyzer, install the required packages:

pip install llama-index llama-index-tools-dappier openai

Setup API Keys

To authenticate and use Dappier and OpenAI, you’ll need valid API keys. You can generate one for free from your Dappier API dashboard.

Python

import os
from getpass import getpass

# Prompt for the Dappier API key securely
dappier_api_key = getpass("Enter your Dappier API key: ")
os.environ["DAPPIER_API_KEY"] = dappier_api_key

You can obtain your OpenAI API key from the OpenAI API dashboard.

Python

# Prompt for the OpenAI API key securely
openai_api_key = getpass("Enter your OpenAI API key: ")
os.environ["OPENAI_API_KEY"] = openai_api_key

Dappier Real Time Search Tool

The DappierRealTimeSearchToolSpec enables LLMs to access real-time data across the web, including the latest news, weather updates, and financial information. This tool is ideal for applications requiring up-to-date, context-rich data.

Initialize the Tool

To utilize the real-time search tool, initialize it as follows:

Python

from llama_index.tools.dappier import DappierRealTimeSearchToolSpec

search_tool_spec = DappierRealTimeSearchToolSpec()

Real-Time Stock Market Data

Access up-to-date financial insights or company-specific news with the search_stock_market_data method:

Python

response = search_tool_spec.search_stock_market_data("explain why AAPL is moving today")
print(response)

Today, Apple Inc. (AAPL) is experiencing movement in its stock price due to several factors:

1. **AI Advancements and Competition**: A recent article from Benzinga highlights that Google's launch of its Pixel 8 series, which includes significant AI advancements, could impact Apple's iPhone innovations. Citi analyst Atif Malik has pointed out that these developments may serve as a catalyst for Apple to enhance its own product offerings. This competitive pressure can influence investor sentiment regarding AAPL.

2. **Market Sentiment and Economic Outlook**: There is a broader market concern as JPMorgan's chief market strategist, Marko Kolanovic, has issued a warning about a potential 20% downturn in the S&P 500, driven by rising interest rates. Such macroeconomic factors can create volatility in tech stocks, including AAPL, as investors reassess their positions amidst fears of a recession.

3. **Strong Jobs Report**: A strong jobs report released today indicates robust non-farm payroll growth, which can impact market dynamics. While this is generally positive news, the mixed signals regarding wage growth and unemployment rates may lead to cautious trading behavior among investors.

These factors combined contribute to the movement in AAPL's stock today, reflecting both competitive pressures and broader economic concerns.

Build a Real-Time Stock Analysis Agent

Now that your API keys are set and packages are installed, you’re ready to build the stock analysis agent. Start by importing the required modules:

Python

import asyncio
from llama_index.llms.openai import OpenAI
from llama_index.tools.dappier import DappierRealTimeSearchToolSpec
from llama_index.core.agent.workflow import AgentWorkflow
from llama_index.core.agent.workflow import AgentStream, ToolCallResult

Initialize the OpenAI model that will power the agent:

Python

llm = OpenAI(model="gpt-4o")

Next, set up the Dappier real-time search tool. This tool allows the agent to query live stock-related news and market insights:

Python

search_tool_spec = DappierRealTimeSearchToolSpec()
tools = search_tool_spec.to_tool_list()

Now define the agent workflow. In this case, the agent acts as a real-time stock explainer agent

Python

workflow = AgentWorkflow.from_tools_or_functions(
    tools,
    llm=llm,
    system_prompt="""
    You are a real-time stock analysis assistant that provides comprehensive, insightful, and timely market analysis. For any given ticker, your job is to:

    1. **Date and Time**:
       - Frist get today's date and time using Dappier real-time search tool and use that date in your future queries

    2. **Explain Intraday Movement**:
       - Use real-time news, social sentiment, analyst commentary, and earnings updates to explain why the stock is moving today.
       - Prioritize significant catalysts (e.g., earnings beats/misses, M&A, regulatory events, analyst upgrades/downgrades, macro news).
       - Include timestamps and sources if available.

    3. **Summarize Key Technicals**:
       - Highlight major technical indicators: 50-day / 200-day moving averages, RSI, MACD, support/resistance levels, and trend direction.
       - Indicate whether the stock is in overbought/oversold territory and breaking out/breaking down from key levels.

    4. **Provide Valuation Insights**:
       - Compare P/E, P/S, P/B, and forward multiples to sector and industry averages.
       - Mention whether the stock is undervalued or overvalued based on historical and relative valuation metrics.

    5. **Contextualize in Broader Market Trends**:
       - Relate the stock’s movement to sector performance, macroeconomic indicators (e.g., interest rates, inflation), and broader market sentiment (e.g., S&P 500 or Nasdaq trends).

    Always return your findings as a detailed explanation in natural language. Be smart and never omit meaningful drivers of price action.
    """,
)

To stream the results from the agent and display both tool interactions and the generated explanation, run the following:

Python

async def run_stock_analysis():
    handler = workflow.run(user_msg=user_prompt)

    seen_agent_output = False

    async for event in handler.stream_events():
        if isinstance(event, AgentStream):
            if not seen_agent_output:
                print("[🧠 Agent]:", end="", flush=True)
                seen_agent_output = True
            print(event.delta, end="", flush=True)
        elif isinstance(event, ToolCallResult):
            seen_agent_output = False
            print(f"\n\n🔧 Tool Used: {event.tool_name}")
            print(f"➡️  Input Args: {event.tool_kwargs}")
            print(f"✅ Output: {event.tool_output}\n")

Finally, launch the agent:

Python

ticker = input("Enter the stock ticker you want to analyze: ").strip().upper()

user_prompt = f"""
Explain this stock ticker: {ticker}

1. Date and Time:
Frist get today's date and time using Dappier real-time search tool and use 
that date in your future queries

2. Real-Time Movement:

3. Technical Analysis:
Summarize key technicals (moving averages, RSI, etc.)

4. Valuation:
Give a smart valuation summary (P/E vs sector, etc.)
