weekly historical data looks off
I am looking at the weekly Historical Data for ^NDX and have a question.
The link is here:
Today is 6/10/2020.
I see 2 dates in the Date column - June 10, 2020 and June 08, 2020.
It looks like the first row (June 10, 2020 ) is the daily data for June 10, 2020 which matches the daily data here:
https://finance.yahoo.com/quote/%5ENDX/history?period1=1560196654&period2=1591819054&interval=1d&filter=history&frequency=1d
My question is about the second date in the Date column (June 08, 2020). I assume this is the weekly data starting on June 08, 2020.
I see the Open is correct at 9805.69 but then there a new High on June 10, 2020 (10,155.20) but the weekly High for June 08, 2020 still shows 10006.90
Can you explain if this is a bug or how this works?
