A) How low can it go? It can drop all the way to 0.0 It can go that low. It won't happen though. And if it did, we'd have much bigger problems than money to worry about.
B) What level SHOULD it be at given the true fundamentals? We have three contributions to the value of an index. (1) Inflation. Inflation causes the price of items, including stock indicies, to grow exponentialy. Over time money is worth less and less, thus to compenate the price of an index will go up and up. (2) Dividend contributions of money from the companies. As dividends are distributed, a portion are reinvested, each year. Due to inflation effects, the divideds and contributions exponentially grow. (3) The number of people in the stock market. The total number of people in the world grows exponentially and the % of people who invest often grows.
As you can see, there SHOULD be a clear exponential growth in stocks, since the true fundamentals grow exponentially. True, people come and go from the market and they will add/subtract how much they have in the market. Thus, on top of the exponential growth there will be some scattered noise. If the scatter is organized, you usually have irrational exuberance (chasing a boom) or irrational pessimism (selling at the bottom when the company is still a sound company). So, what does this look like? On a log graph, it should look like a sine-like wave along a linearly increasing line.
I made that graph of the DJIA for you. Yep, it looks like what it should with irrational booms in 1920s and late 1990s and crashes in 1930s and inflation problems in the 1970s. According to the linear portion, where should we be? 7600.
C) As you can see, the DJIA rarely drops much. Instead, to revert to the mean, it pauses. As described above, the DJIA (and other indicies) tend to go on "hold" for 15-20 years. Thus, we've been in the 9000-14000 hold for half of that time. According to this estimate, it will go as low as 9000, but it'll jump right back to the 14000 mark before coming back to the middle again.
D) You have estimates that stocks and indicies always go up. 10% a year I hear is what you can expect from these exubberant people. So, under this measure, today's value is as low as it should go. 11800.
Which do we believe? 0? 7600? 9000? 11800? That is the great mystery. If you could make these predictions accurately, you'd be the wealthiest person in the world. You can't. I can't. No one can.
My personal belief? We will revert to the line, not by falling a lot, but by holding steady. In the year 2016, we will have reached that linear graph even if the DJIA stays at 11800. Since the DJIA historically goes on 15-20 year holds, 2016 is right near that 15-20 year end. I think the holding period is the most realistic estimate. For the next 8 years the DJIA will be in the 9000 - 14000 range. Thus, my long-winded answer to your question is 9000.
