> Hi,

> Sorry for sending this solution so late. I am new in Ruby  
> programming!!
>
> I would like to share my solution with the community.
>
> I wrote a script that fetches stock prices from Yahoo Finance and  
> compares with purchase price and amount stored in a separate text  
> file.
>
> In the file stock.txt insert stock name, purchase date, stock price  
> and amount (separated by ";").
