ticker = yf.Ticker("AAPL")
institutional_holders = ticker.institutional_holders
major_holders = ticker.major_holders
mutualfund_holders = ticker.mutualfund_holders
2. Stock Quotes & Fundamentals
# Real-time/historical quotes
ticker = yf.Ticker("NVDA")
hist = ticker.history(period="1mo") # 1d, 5d, 1mo, 3mo, 6mo, 1y, max
info = ticker.info # Company fundamentals
