💥 Is yahoo finance broken?

[paintdog]

Describe bug

Since yesterday, Yahoo Finance has not been providing data for several stocks, making it impossible for me to download them using your software. For example, for Honeywell – a Nasdaq 100 stock (!!!) – Yahoo Finance states: "There are no [data] in the selected time period."

I understand that this is likely a Yahoo Finance issue, but your software becomes unusable if the platform behind it stops providing data. As far as I can tell, this issue has affected a wide range of stocks (some US, mostly European) since yesterday.

Are others experiencing this problem as well? Does this happen from time to time, or is it a sign of a bigger issue? Any suggestions? Will Yahoo fix this problem, or are they already aware of it? Is Yahoo discontinuing data support?

Simple code that reproduces your problem

No simple code, as I use your software within my own modules.

df.head()

Are others experiencing this problem as well? Yes , I am also experiencing the same.

Does this happen from time to time, or is it a sign of a bigger issue? Its stable, using since lot of time. May be some issue at Yahoo Side.

Will Yahoo fix this problem, or are they already aware of it? Is Yahoo discontinuing data support? May be will get clarity after some time.

Getting the same problem with a number of (but not all) .NZ tickers.

USF.NZ not working. GNE.NZ working.

USF.NZ not working. GNE.NZ working.

Replying to myself - https://finance.yahoo.com/quote/USF.NZ/history/ is empty which is probably the cause of the problem

It seems Yahoo Finance has fixed the issue (Honeywell)!?

For :

GetFacebookInformation = yfinance.Ticker("META")
print(*values: GetFacebookInformation.info)

I get:

requests.exceptions.HTTPError: 404 Client Error: Not Found for url: https://query2.finance.yahoo.com/v6/finance/quoteSummary/META?modules=financialData&modules=quoteType&modules=defaultKeyStatistics&modules=assetProfile&modules=summaryDetail&ssl=true

conda list | grep finance
yfinance                  0.2.28             pyhd8ed1ab_0    conda-forge

P.S. Putting the above url into the browser produces:

Seems like it started to work today....

I just wanted to add that I'm getting the same issue too. I hope there is a solution for this.

Can someone please clarify: is this issue solved, and is it possible to use yfinance again? Does yfinance 0.2.43 somehow solve the core issue with Yahoo changing their data availability? Can't quite see if Yahoo has made the data unavailable how a software update would fix that.

[ValueRaider]

Version 0.2.32 added cookie & crumb, it helped a lot. I'm not sure what the remaining issue is - spam? old cookie? country-specific?

(deleted @az-z comments because using old version)

[cdcv]

Thank you ValueRaider. Does the cookie/crumb fully restore all prior functionality? Again, my understanding is that YFinance had removed considerable functionality from their API whether you're auth'd or not, like detailed historical data, and having a cookie wouldn't solve that. Am I miss-understanding? Thx again.

[ValueRaider]

Yahoo had removed considerable functionality from their API

This would break their website so I don't believe this. You could just install yfinance use it.

According to the first paragraph of this article:

Exploring Alternatives to the Yahoo Finance API
https://eodhd.medium.com/exploring-alternatives-to-the-yahoo-finance-api-aa0415085cc5

Yahoo Finance recently limited access to its historical data downloads to Gold membership subscribers, which costs $50 per month (or $500 per year with a discount).

According to this help article, it looks like you can download your historical data if you pay for a Gold subscription.
