Warp: The best way to answer that questions is for yourself. And the best way to do it is to line up historical TNX charts with the same SPX, INDU and COMPX charts and see how they compare.
Since the TNX starts trading earlier than the equities markets it use to be one of the tools (coupled with the futures) to get a early idea as to what to expect, but with extended hour trading you now have pre market looks at just about everything.
At any rate, look the charts over weekly, daily and various intraday time frames.
