Investment Analysis Workflow

When the user asks about stock performance, portfolio advice, or market analysis:

Get live data via CLI — quotes, positions, K-line history, intraday
Get news/catalysts via CLI — prefer Longbridge first; fall back to WebSearch only if insufficient
Combine — price action + volume + catalyst → analysis + suggestion

# Market data
longbridge quote SYMBOL.US
longbridge positions                # stock positions
longbridge portfolio                # P/L, asset distribution, holdings, cash (always pull when user asks about "my portfolio")
longbridge portfolio short-margin   # short-selling margin deposit details per position
longbridge kline history SYMBOL.US --start YYYY-MM-DD --end YYYY-MM-DD --period day
longbridge intraday SYMBOL.US

# News & content (prefer these over WebSearch)
longbridge news SYMBOL.US           # latest news articles
longbridge news detail <id>         # full article content
longbridge news search "keyword"    # keyword search across news articles
longbridge filing SYMBOL.US         # regulatory filings list (8-K, 10-Q, 10-K, etc.)
longbridge topic SYMBOL.US          # community discussion
longbridge topic search "keyword"   # keyword search across community topics
longbridge market-temp              # market sentiment index (0–100)

# Fundamentals & analysis
longbridge financial-statement SYMBOL.US --kind ALL   # hierarchical IS/BS/CF with YoY
longbridge financial-report SYMBOL.US --latest        # key KPI summary (revenue/EPS/ROE)
longbridge analyst-estimates SYMBOL.US                # EPS consensus (high/low/mean/median)
longbridge valuation-rank SYMBOL.US                   # daily PE/PB/PS industry percentile rank

# IPO
longbridge ipo subscriptions        # HK IPOs in subscription stage
longbridge ipo calendar             # all upcoming and recent IPOs
longbridge ipo us-subscriptions     # US IPOs in subscription stage

# Account
longbridge assets                   # full asset overview: cash, buying power, margin, risk level
longbridge statement --help         # check subcommands for statement export options
longbridge bank-cards               # bank cards linked to the account
longbridge withdrawals              # withdrawal history
longbridge deposits                 # deposit history

# Institutional investors (SEC 13F)
longbridge investors                # top active fund managers by AUM
longbridge investors <CIK>          # holdings for a specific investor by CIK
longbridge insider-trades SYMBOL.US # SEC Form 4 insider transaction history

For commands with complex flags, always run longbridge <command> --help for current options.

Only fall back to WebSearch when Longbridge news is insufficient (e.g., breaking news not yet indexed, macro events unrelated to a specific symbol).
