$this->bbcode_second_pass_quote('alokin', 'I') am not an economist - and will never be, so forgive me the stupid question: what represents the ups and downs of the indexes? The volume of stocks traded?

If the DOW is not an index of volume which is the index of volume then?
It is there....Just that most people just look at the price.
Volume is the number of shares that was traded.
This can be done on sectors, indicies, individual shares etc. as long as you have access to charting that supports it.
Volume is ususally not a very useful indicator but is comes in handy when looking at breakouts and counter trends and possibly exhaustion.
A counter trend rally would occur for instance when share prices have been dropping. New shorts get careful to enter, weak long hands are already out and strong hands have stopped selling. So volume starts to dry up.
Bottom fishers get in and turn up the price. But if there isn't broad support for upswing in prices it will be at relatively low volume. (i.e. as there aren't that many sellers left at that price, it doesn't take much to get the price to jump up, often violently.)
If the upswing or counter trend rally however doesn't generate more volume it is likely that it will stagnate. Previously hesitant longs can get a new chance to offload at better prices and shorts get a new entry position. Result - a dead cat bounce.
Counter trends can be tricky to trade and often do ABC waves (read up on elliott wave). It is sometimes hard to determine if it is setting it self up for new up trend. Volume is one of those easier indicators to follow. But do a bit more homework if you intend to trade it as volme is just one indicator of many.
What was said about counter trends also works in the reverse.
i.e. counter trends happen both in up and down markets in similar ways.
