Even though you have found BID's beta using the Yahoo financial website, you would like to make a comparison of that beta estimation to another to check for consistency. Go to the Value Line website and at the top of the page towards the center click on the BROWSE RESEARCH tab. Now in the "Search" box that appears in the upper right side, type in the letters "BID" and select Sotheby’s from the list. The beta for BID should be listed under the "QUOTES" section of the web page that appears. What is the Value Line estimation of beta for BID? Assuming that the two beta estimations are different (Yahoo vs. Value Line), explain how the two financial websites, on the same date, can provide two different beta estimates for BID (assuming no mistakes or rounding in the calculations)?
