I have a doubt about some values that I got when I run the code below:
ek.get_data('5411.T', fields=["TR.WACCBeta.date","TR.WACCBeta.value"], parameters={'SDate':'2020-03-01', 'EDate':'2020-03-31', 'Frq':'D'})[0]
I found seemingly unreasonable abrupt change in values on 2020-03-15 and 2020-03-16:
5411.T 2020-03-14T00:00:00Z 1.732474
5411.T 2020-03-15T00:00:00Z 1.253408
5411.T 2020-03-16T00:00:00Z 1.161265
5411.T 2020-03-17T00:00:00Z 1.711114
5411.T 2020-03-18T00:00:00Z 1.742852
5411.T 2020-03-19T00:00:00Z 1.798471
I understand that this beta is calculated with the order of preference: 5Y monthly, 3Y weekly, 2Y weekly, 180D daily, 90D daily, and I suspect that it has something to do with these settings of duration and frequency. The thing is that 5411.T has long track record and I'm sure that 5Y monthly data has been always available at least recently. Could somebody look into this sudden level shift followed by come-back on the original track? Thank you!
