I am a software engineer for almost 40 years in wall street. I can;t understand why i kept on finding bugs inyour website. I love yahoo and have been a user for the past two decades.
I found on bug again. Here's the description:

select a stock on the portfolio list and the chart (summary) will display. If you refresh the chart page. you will see your list of stock in portfolio (on the right side of screen) has no company description. THEN, if you select any stocks on the portfolio list, the screen will stay on the same screen and won't display the new chart of the stock selected.
