A common question is how the stockpicking project will be graded. It is intended to be fun and help you interact with the financial markets in a personal way. Thus, grading will essentially be based on the following. If you complete the assignment and turn in a report that has one overall page single spaced for items 1 and 3 (your own few paragraphs of writing), and another couple pages of records with item 2, you will receive full credit. Anything less, will receive half credit.

Please see the attachment for the instruction. This due by Thursday.
