yfinance download for tickers with sunday working day.

[BottleNeck2021]

Describe bug

Hello,

steps taken are as follows:
yf.download("NBK.KW")
resulting output

we get only values for
Monday
Tuesday
Wednesday
Thursday

Please note GCC markets have their weekends as Friday and Saturday.

So the first working day is Sunday.

Exception: UAE/Dubai has Saturday/Sunday as weekend.

Simple code that reproduces your problem

yfinance.download("NBK.KW")

If Yahoo doesn't have Sundays, not sure what yfinance can do.

Dear @ValueRaider,
Got it ...

I checked most recent prices and found that at some point Yahoo fixed the problem.

Thank you !!
