claude-finance-kit

Vietnamese stock market analysis toolkit for AI coding assistants.
Fundamentals • Technicals • Macro • News • Screening • Fund Analysis

Overview

claude-finance-kit is a Python library + AI plugin that gives your coding assistant deep access to Vietnamese stock market data and analysis tools. It works as a Claude Code plugin (via Marketplace), and also supports Cursor and GitHub Copilot through a CLI installer.

Ask natural language questions — the plugin auto-routes to the right analysis workflow:

"Analyze FPT stock"
"Market overview today"
"Compare VNM vs MSN"
"Latest news sentiment for HPG"

Example: Stock Analysis in Action

2. Install the AI plugin

/plugin marketplace add hongbietcode/claude-finance-kit

/plugin install claude-finance-kit@hongbietcode-claude-finance-kit

npx claude-finance-kit-cli init --ai cursor    # Cursor
npx claude-finance-kit-cli init --ai copilot   # GitHub Copilot
npx claude-finance-kit-cli init --ai claude    # Claude Code (CLI alternative)

Quick Start

Once installed, just ask naturally — the plugin auto-invokes the right skill:

"Analyze FPT stock"                                        → finance-kit (stock deep dive)
"Market overview today"                                    → finance-kit (market briefing)
"Compare VNM vs MSN"                                       → finance-kit (comparative)
"Latest news sentiment for HPG"                            → finance-kit (news sentiment)
/finance-kit "tôi mua HPG ở giá 26.6k, có nên bán không" → finance-kit (full analysis)

Python Library Usage

from claude_finance_kit import Stock, Market, Macro, Commodity, Fund

# Stock data
stock = Stock("FPT")
stock.quote.history(start="2025-01-01", end="2025-12-31")
stock.finance.income_statement(period="quarter", lang="en")
stock.company.overview()

# Market valuation
market = Market("VNINDEX")
market.pe(duration="5Y")
market.top_gainer(limit=10)

# Macro indicators
macro = Macro()
macro.gdp()
macro.cpi()
macro.interest_rate()

# Commodities
commodity = Commodity()
commodity.gold()
commodity.oil()

# Fund analysis
fund = Fund()
fund.listing("STOCK")

Technical Analysis

from claude_finance_kit import Stock, Indicator

stock = Stock("FPT")
df = stock.quote.history(start="2025-01-01", end="2025-12-31")
df = df.set_index("time")

ind = Indicator(df)
ind.trend.sma(length=20)
ind.trend.ema(length=50)
ind.momentum.rsi(length=14)
ind.momentum.macd(fast=12, slow=26, signal=9)
ind.volatility.atr(length=14)
ind.volume.obv()

Data Sources

Source fallback: If VCI returns 403 (common on cloud IPs), the library automatically falls back to KBS. You can also specify manually: Stock("FPT", source="KBS").
