Ok, I see some days the 30 yr T-bonds move sideways, today it moved up, a few days back moved down.. What the heck is the reason the markets move like this? I mean, how can I be prepared for today's 20 pt moveup in this particular market? Same with the dow, one day it'll be down 200 points, the next day it will be up 20. Why do markets do this? The most clearest explanation of why would be appreciated.. I'm not into reading real techincal definitions..
