title: Yahoo Finance Api - Missing data for symbols
body: <p>I'm using Yahoo Finance Api to extract stockrates. To find the symbols using <a href="http://finance.yahoo.com/" rel="nofollow">Yahoo Finance</a> - but oddly a few of the symbols that Yahoo presents, doesn't return any data when using the API?!</p>
  
  <p>Here are a few examples (Try looking them up with the above url):</p>
  
  <ul>
  <li>DKIEUIXBNP.CO</li>
  <li>DKIENGKEUO.CO</li>
  <li>DKIGLOIXVAKK.CO</li>
  </ul>
  
  <p>But when trying to extract data. The symbol seems to be unknown.</p>

  <p>Using the YQL, it says "Unknown ticker symbol"</p>
  
  <p><a href="http://query.yahooapis.com/v1/public/yql?q=select%20%2a%20from%20yahoo.finance.quotes%20where%20symbol%20in%20%28%22DKIGLOIXVAKK.CO%22%29&amp;env=store://datatables.org/alltableswithkeys" rel="nofollow">YQL Example</a></p>
  
  <p>Why o' why?</p>
  
  <p>Thanks in advance</p>
