Hello, I am 17 and find myself a little confused by all this talk of cost basis and the lot. I purchased 30 shares of ziff davis at 17.562 and recently received shares of KME. How do I adjust the current value to reflect the dividend received and the KME shares received? If you could, please explain in laymans terms, as I am a relatively new investor and would like to learn for the future. Thanks in advance... ---David T.
