企业研究#
进行企业研究或竞争分析是任何商业策略的关键部分。在本笔记本中，我们将演示如何创建一个代理团队来完成这项任务。虽然将任务转化为代理实现的方式有很多种，但我们将探索一种顺序方法。我们将创建与研究流程步骤相对应的代理，并为它们提供执行任务的工具。
搜索代理：在网络上搜索企业相关信息。将拥有搜索引擎API工具来获取搜索结果。
股票分析代理：从金融数据API获取公司股票信息，计算基本统计数据（当前价格、52周最高价、52周最低价等），并生成年初至今的股价走势图，保存到文件中。将拥有金融数据API工具来获取股票信息。
报告代理：根据搜索和股票分析代理收集的信息生成报告。
首先，让我们导入必要的模块。
from autogen_agentchat.agents import AssistantAgent
from autogen_agentchat.conditions import TextMentionTermination
from autogen_agentchat.teams import RoundRobinGroupChat
from autogen_agentchat.ui import Console
from autogen_core.tools import FunctionTool
from autogen_ext.models.openai import OpenAIChatCompletionClient
定义工具#
接下来，我们将定义代理用于执行任务的工具。我们将创建一个使用Google搜索API在网络上搜索企业信息的google_search函数。我们还将创建一个使用yfinance库获取公司股票信息的analyze_stock函数。
最后，我们将这些函数封装到FunctionTool类中，以便在我们的代理中使用它们作为工具。
注意：google_search函数需要API密钥才能工作。您可以在本笔记本所在目录中创建一个.env文件，并添加您的API密钥：
GOOGLE_SEARCH_ENGINE_ID =xxx
GOOGLE_API_KEY=xxx
同时安装所需的库：
pip install yfinance matplotlib pytz numpy pandas python-dotenv requests bs4
# !pip install yfinance matplotlib pytz numpy pandas python-dotenv requests bs4
def google_search(query: str, num_results: int = 2, max_chars: int = 500) -> list: # type: ignore[type-arg]
import os
import time
import requests
from bs4 import BeautifulSoup
from dotenv import load_dotenv
load_dotenv()
api_key = os.getenv("GOOGLE_API_KEY")
search_engine_id = os.getenv("GOOGLE_SEARCH_ENGINE_ID")
if not api_key or not search_engine_id:
raise ValueError("API key or Search Engine ID not found in environment variables")
url = "https://customsearch.googleapis.com/customsearch/v1"
params = {"key": str(api_key), "cx": str(search_engine_id), "q": str(query), "num": str(num_results)}
response = requests.get(url, params=params)
if response.status_code != 200:
print(response.json())
raise Exception(f"Error in API request: {response.status_code}")
results = response.json().get("items", [])
def get_page_content(url: str) -> str:
try:
response = requests.get(url, timeout=10)
soup = BeautifulSoup(response.content, "html.parser")
text = soup.get_text(separator=" ", strip=True)
words = text.split()
content = ""
for word in words:
if len(content) + len(word) + 1 > max_chars:
break
content += " " + word
return content.strip()
except Exception as e:
print(f"Error fetching {url}: {str(e)}")
return ""
enriched_results = []
for item in results:
body = get_page_content(item["link"])
enriched_results.append(
{"title": item["title"], "link": item["link"], "snippet": item["snippet"], "body": body}
)
time.sleep(1) # 请尊重服务器
return enriched_results
def analyze_stock(ticker: str) -> dict: # type: ignore[type-arg]
import os
from datetime import datetime, timedelta
import matplotlib.pyplot as plt
import numpy as np
import pandas as pd
import yfinance as yf
from pytz import timezone # type: ignore
stock = yf.Ticker(ticker)
# 获取历史数据（1年数据以确保有足够数据计算200日均线）
end_date = datetime.now(timezone("UTC"))
start_date = end_date - timedelta(days=365)
hist = stock.history(start=start_date, end=end_date)
# 确保数据存在
if hist.empty:
return {"error": "No historical data available for the specified ticker."}
# 计算基础统计量和附加指标
current_price = stock.info.get("currentPrice", hist["Close"].iloc[-1])
year_high = stock.info.get("fiftyTwoWeekHigh", hist["High"].max())
year_low = stock.info.get("fiftyTwoWeekLow", hist["Low"].min())
# 计算50日和200日移动平均线
ma_50 = hist["Close"].rolling(window=50).mean().iloc[-1]
ma_200 = hist["Close"].rolling(window=200).mean().iloc[-1]
# 计算年初至今价格变动及百分比变动
ytd_start = datetime(end_date.year, 1, 1, tzinfo=timezone("UTC"))
ytd_data = hist.loc[ytd_start:] # type: ignore[misc]
if not ytd_data.empty:
price_change = ytd_data["Close"].iloc[-1] - ytd_data["Close"].iloc[0]
percent_change = (price_change / ytd_data["Close"].iloc[0]) * 100
else:
price_change = percent_change = np.nan
# 确定趋势
if pd.notna(ma_50) and pd.notna(ma_200):
if ma_50 > ma_200:
trend = "Upward"
elif ma_50 < ma_200:
trend = "Downward"
else:
trend = "Neutral"
else:
trend = "Insufficient data for trend analysis"
# 计算波动率（日收益的标准差）
daily_returns = hist["Close"].pct_change().dropna()
volatility = daily_returns.std() * np.sqrt(252) # 年化波动率
# 创建结果字典
result = {
"ticker": ticker,

"volatility": volatility,
}
# 将 numpy 类型转换为 Python 原生类型以获得更好的 JSON 序列化
for key, value in result.items():
if isinstance(value, np.generic):
result[key] = value.item()
# 生成图表
plt.figure(figsize=(12, 6))
plt.plot(hist.index, hist["Close"], label="Close Price")
plt.plot(hist.index, hist["Close"].rolling(window=50).mean(), label="50-day MA")
plt.plot(hist.index, hist["Close"].rolling(window=200).mean(), label="200-day MA")
plt.title(f"{ticker} Stock Price (Past Year)")
plt.xlabel("Date")
plt.ylabel("Price ($)")
plt.legend()
plt.grid(True)
# 保存图表到文件
os.makedirs("coding", exist_ok=True)
plot_file_path = f"coding/{ticker}_stockprice.png"
plt.savefig(plot_file_path)
print(f"Plot saved as {plot_file_path}")
result["plot_file_path"] = plot_file_path
return result
google_search_tool = FunctionTool(
google_search, description="Search Google for information, returns results with a snippet and body content"
)
stock_analysis_tool = FunctionTool(analyze_stock, description="Analyze stock data and generate a plot")
定义智能体#
接下来，我们将定义执行任务的智能体。我们将创建一个search_agent用于搜索公司信息，一个stock_analysis_agent用于获取公司股票信息，以及一个report_agent用于根据其他智能体收集的信息生成报告。
model_client = OpenAIChatCompletionClient(model="gpt-4o")
search_agent = AssistantAgent(
name="Google_Search_Agent",
model_client=model_client,
tools=[google_search_tool],
description="Search Google for information, returns top 2 results with a snippet and body content",
system_message="You are a helpful AI assistant. Solve tasks using your tools.",
)
stock_analysis_agent = AssistantAgent(
name="Stock_Analysis_Agent",
model_client=model_client,
tools=[stock_analysis_tool],
description="Analyze stock data and generate a plot",
system_message="Perform data analysis.",
)
report_agent = AssistantAgent(
name="Report_Agent",
model_client=model_client,
description="Generate a report based the search and results of stock analysis",
system_message="You are a helpful assistant that can generate a comprehensive report on a given topic based on search and stock analysis. When you done with generating the report, reply with TERMINATE.",
)
创建团队#
最后，让我们创建由这三个智能体组成的团队，并设置它们对公司进行研究。
team = RoundRobinGroupChat([stock_analysis_agent, search_agent, report_agent], max_turns=3)
我们使用max_turns=3将轮次限制为与团队中智能体数量相同。这实际上使智能体以顺序方式工作。
stream = team.run_stream(task="Write a financial report on American airlines")
await Console(stream)
await model_client.close()
