Have you ever noticed how the stock market has such volatile swings throughout the day - down 700 to up 300 and finishing at minus 200? Up 400, down 200, close at plus 50? I've come to the conclusion that it really does little good to get a mid-day market report. It will all change by day's end. Even at the 4:00 bell the numbers still move up and down for another 15-20 minutes.
It reminds me of the NBA (National Basketball Association). Those familiar with the game will know what I'm talking about. If you don't know or don't care about professional basketball, let me just say that you can essentially ignore all but the last 2 minutes or so of the game. That's when the game is won or lost.
In an NBA contest, it's commonplace for one team to outscore the other by 20-30 points in a "run" only to be matched by the other team outscoring them in similar fashion later in the contest. How much one team is ahead or behind is ususally of little consequence until right near the end. The lead can go back and forth or the amount of that advantage can shrink dramatically in those closing seconds.
While the Dow (stock market) and the NBA have no direct correlation or relationship (at least none that I know of), it's interesting that they both behave similarly in a given day or contest.
