cannot fetch fundamental data

Dear all,

As I try to incorporate some fundamental data into my algorithm, I found there are some problems when I try to fetch the fundamental data for some specific stocks. (please see the following code)

def initialize(context):  
    set_symbol_lookup_date('2015-08-01')  
    set_long_only()  
    context.stocks = symbols(''DIS','CMCS_A','FOX',,'TWC','NFLX')

def before_trading_start(context, data):  
    """  
      Called before the start of each trading day.  
      It updates our universe with the  
      securities and values found from get_fundamentals.  
    """  
    global fundamental_df  


    fundamental_df = get_fundamentals(  
        query(  
            fundamentals.asset_classification.growth_grade,  
            fundamentals.earnings_ratios.diluted_eps_growth,  
        )  
        #.filter(fundamentals.valuation.market_cap != None)  
        #.filter(fundamentals.valuation.shares_outstanding != None)  
        #.order_by(fundamentals.valuation.market_cap.desc())  
        #.limit(num_stocks)  
    )

    print fundamental_df[symbol('FOX')]  

However, I get an error message:error message. Does anyone have ever meet the same problem?

Thanks a lot!!

Hi,

It seems like there are time frames in which FOX isn't present in the fundamentals data -- that's the underlying cause of the error. When I query the data for the FOX ticker in research and ask for data back on a quarterly basis, I'm only getting data back to 2013:

df = get_fundamentals(  
        query(  
            fundamentals.company_reference.sid,  
            fundamentals.valuation.market_cap  
        )  
        .filter(fundamentals.company_reference.sid==5530) # the sid for FOX  
        , "2015-09-20", '40q')

df.loc['market_cap']  

which gives me
security Equity(5530 [FOX]) algo_date 2013-09-23 00:00:00+00:00 72460104733 2013-12-23 00:00:00+00:00 75368065061 2014-03-24 00:00:00+00:00 73457444451 2014-06-23 00:00:00+00:00 76141466343 2014-09-22 00:00:00+00:00 74308611650 2014-12-22 00:00:00+00:00 78482878983 2015-03-02 00:00:00+00:00 71852749526 2015-06-22 00:00:00+00:00 67464131631 2015-09-18 00:00:00+00:00 54666806887

This matches a corporate action in 2013 when Newscorp went from the NWS ticker to the FOX ticker.

We'll need to dig a bit more as to whether this corporate action is being handled correctly in our data.

Hi Josh,

Thanks a lot for your explanation. Is there any suggestions to get around?
