Quote At Variance With Chart for TZA?

• compare auto insurance quotes
• accounts receivable t chart

When I use finance.yahoo.com to look up historical quotes for TZA the numbers given don't correlate to the charts . For instance the quote for Tue, Aug 09, 2011 says the closing price was 51.22 but the chart found at finance.yahoo.com has the ETF in the 200s for the same date. I know I'm not seeing something right but I don't know what.


I know there is nothing wrong with the yahoo numbers or chart. I'm wondering how this ETF is calculated so that the quote and the chart could be at such variance.


Thanks.
