Cleaning list of tickers

General
1

I created a list of tickers by combining the tickers belonging to s&p500, dow, nasdaq and russel2000 and then I removed the duplicates.



Some tickers have a ^ in their symbol and yahoo finance fails when downloading its data (I don't know why). Therefore I'm trying to get rid of them (that means I want to remove from my list all the tickers containing ^ ).



as an example (not real tickers)

list = ['AAA', 'BBB', 'C^CC', 'ABR^E', 'EDFT', 'LK^U', 'POKI']



for i in list:

    if "^" in i:

        list.remove(i)



output

['AAA', 'BBB', 'ABR^E', 'EDFT', 'POKI']

I don't understand why.

thansk a lot.

First:

pip install yfinance --upgrade --no-cache-dir





In Yahoo Finance (yf) tickers, the ^ symbol is often used to indicate indices rather than individual stocks or ETFs. For example:

  1. ^GSPC: Refers to the S&P 500 index, representing the performance of 500 large-cap U.S. companies.
  2. ^DJI: Refers to the Dow Jones Industrial Average.
  3. ^IXIC: Refers to the NASDAQ Composite index.
  4. ^VIX: Refers to the Volatility Index (VIX), also known as the "fear index."
Try downloading Data for there:
import yfinance as yf
# Download S&P 500 index data
sp500_data = yf.download('^GSPC', start='2020-01-01', end='2023-12-31').

You can create list of failed tickers and look for them on yahoo finance, probably the ticker is changed.
