pegRatio missing from yfinance.info since June 2025 (worked before) #2570
Description
Describe bug
The pegRatio field from yfinance.Ticker(ticker).info suddenly returns None for many tickers.
Until May 30, 2025, this worked fine for stocks like AAPL, MSFT, GOOGL. Since June, it seems to have silently broken – the field is missing entirely in the .info dictionary.
I checked that the PEG ratio is still visible on Yahoo Finance directly, so the data exists.
Simple code that reproduces your problem
import yfinance as yf
ticker = yf.Ticker("AAPL")
info = ticker.info
print("PEG Ratio:", info.get("pegRatio")) # returns None
Debug log from yf.enable_debug_mode()
PEG Ratio key missing from .info output. Tried with yf.enable_debug_mode(), but no specific error is shown – PEG key just doesn't appear anymore in the dictionary.
Bad data proof
The PEG ratio is still listed here:
https://finance.yahoo.com/quote/AAPL/key-statistics/
Example:
PEG Ratio (5 yr expected): 1.97 (as of July 2025)
But .info.get("pegRatio") returns None.
