I was skeptical of mortgage thing, and went my Grandma started talking about flipping houses and can't lose, I knew the gravy train was headed for a cliff.

This is so awesome - the only "fundamental" analysis I ever do is listening when my mom wants to start doing something. Then I know it has reached a top. Started out when she was asking about stocks like Oracle and Pets.com. Kept going when she wanted to start buying houses in 2008, etc.

But I agree that Technical Analysis trumps all. People can argue all day about what the price "should be" but nobody can argue about what it is right now and what it has been in the past.
