jq

Install

brew install jq
npm install yahoo-finance2
sudo ln -s /opt/homebrew/bin/yahoo-finance /usr/local/bin/yf

Usage

The tool is available as yf. It outputs JSON, which can be piped to jq for filtering.

yf <module> <symbol> [queryOptions]

Modules

Quote (Real-time Price & Data)

Get real-time price, change, and basic data.

yf quote AAPL
yf quote AAPL | jq '.regularMarketPrice'

Quote Summary (Fundamentals & More)

Get detailed modules like earnings, financial data, and profiles.

# Get specific sub-modules
yf quoteSummary AAPL '{"modules":["assetProfile", "financialData", "defaultKeyStatistics"]}'

# Common modules to request:
# - assetProfile (Company info, sector)
# - financialData (Target price, margins, cash)
# - defaultKeyStatistics (Enterprise value, float, shares)
# - calendarEvents (Earnings dates)
# - earnings (History and trend)
# - recommendationTrend (Analyst ratings)
# - upgradeDowngradeHistory

Insights

yf insights AAPL

Search

Search for symbols.

yf search "Apple"
yf search "BTC-USD"

Historical Data (Deprecated)

Get historical OHLCV data. Note: historical is deprecated; use chart instead.

# Deprecated - use chart instead
yf historical AAPL '{"period1":"2024-01-01","period2":"2024-12-31"}'

# Recommended: use chart
yf chart AAPL '{"period1":"2024-01-01","period2":"2024-12-31"}'

Examples

Quick Price Check

# Full JSON then filter with jq
yf quote NVDA | jq '{symbol: .symbol, price: .regularMarketPrice, changePct: .regularMarketChangePercent}'

Next Earnings Date

# Use single quotes around the JSON option in zsh/bash
yf quoteSummary TSLA '{"modules":["calendarEvents"]}' | jq '.calendarEvents.earnings.earningsDate'

Analyst Recommendations

yf quoteSummary AAPL '{"modules":["recommendationTrend"]}'

Company Profile

yf quoteSummary MSFT '{"modules":["assetProfile"]}'

Historical OHLCV

# Using chart (recommended)
yf chart AAPL '{"period1":"2024-01-01","period2":"2024-12-31","interval":"1d"}' | jq '.quotes[0:5]'

# Using historical (deprecated, but still works)
yf historical AAPL '{"period1":"2024-01-01","period2":"2024-12-31","interval":"1d"}' | jq '.[0:5]'

Search for Symbols

yf search 'Apple'
yf search 'BTC-USD'

Trending Symbols (US)

yf trendingSymbols US

Insights (valuation, outlook)

Troubleshooting

Cookies: The tool automatically handles cookies (stored in ~/.yf2-cookies.json). If you encounter issues, try deleting this file.
JSON Output: The output is pure JSON. Use jq to parse it for scripts or readability.

Additional tips:

If you see authentication or parsing errors, delete the cookie file and retry:

rm -f ~/.yf2-cookies.json
yf quote AAPL

On macOS with zsh, prefer single quotes around JSON option arguments and use double quotes inside (see examples above).
If you want a compact numeric value only (no jq), use a short jq filter, e.g.:

yf quote AAPL | jq -r '.regularMarketPrice'
