Resample Weekly into Daily CSV DataFrame

I have a database that releases weekly data on Friday afternoons, for data ending on the previous Tuesday. I am trying to re-sample that data into daily up to yesterdays date.

I keep running the code below, but it is not resampling into daily business days:

df=pd.concat([specl,specs,comml,comms,smalll,smalls], join='inner', axis=1)
df.resample('B').ffill()

You'll likely get better answers if you add a small sample of your input data in your question. See also How to create a Minimal, Complete, Verifiable example.

Maybe you forget the sum() method with resample?

df=pd.concat([specl,specs,comml,comms,smalll,smalls], join='inner', axis=1)
df = df.resample('B').sum().ffill()
