This code can help you:

i=0
 for j in range(Log_return.shape[1]):
#j chooses the column of Log dataframe
#shape[1] gives number of columns
 for k in range(len(Log_return)):
# k chooses the rows one by one of jth column

 shares.iloc[i,0]*Log_return.iloc[k,j]
#you can multiply and even store the values or do any operations you want 
 i+=1
#i determines the row of shares dataframe
