Some longer-range ValuationRatios class members returning 0

[simonsonjack]

Expected Behavior

A call such as

qb = QuantBook()
begin = datetime(2009,2,27)
end = datetime.now()
stocks = ["AAPL","MSFT","ADBE","IBM","BRK.B"]
data = qb.GetFundamental(stocks, 'ValuationRatios.EVToEBIT3YrAvg' ,begin,end).fillna(method='ffill')
df = data.apply(pd.to_numeric)

should return a data frame of values. This problem exists for a number of ValuationRatios class members, the full extent of which is unknown.

Actual Behavior

The above call returns the dataframe

It seems that now BRK.B is the only one returning 0 for the first years of data. I think this is more a data issue? @Jay-Jay-D @simonsonjack
