Rule #1 Question of the Week: Tech Businesses and Stock Options (WDC)

This week's Question of the Week for Phil Town:

Q:

Hello Phil Town,

I'm a reader of your book from Kuwait. I'm a complete novice in the stock market, I'm trying to learn while reading your book. I never seriously considered the stock market until I read your book, thank you.

I was checking out Western Digital (WDC) on MSN money and I was amazed by what I saw in the insider trading page. Is this really a good example of suspicious selling or is this normal?
