2012′s trading volume went from a state of sluggishness, to something closely resembling comatose, with a slow and unsteady pulse that only serves to reassure analysts it's still alive.

Indeed, market volume has been on the decline for some time, but this week's activity has still been surprisingly lifeless.

Consider that Monday's NYSE volume was the lowest non-holiday trading day volume in over a decade. Tuesday's trading volume was 50 million shares greater than Monday's, disappointing conservative estimates of 100 million shares higher.

What changed?
It's still unclear what's going on in the market to make trading volume so anemic. But as a start, or maybe a clue, we repeat what UBS floor trader Art Cashin shared in an interview with CNBC:

Tuesday's anomaly was caused by two somewhat unusual things. The first was a slight slowing of the trading rate between 2:00 and 3:00. The run rate between those two hours is normally very consistent. Any changes are almost always the result of some news event. Yesterday, there was no news that we could find. A bit strange.

The other anomaly was not quite as rare. It was simply a disinterest in market on close orders. The normal runoff in those orders averages 100 to 150 million shares. Yesterday, it was barely 50 million. Trading geeks (like yours truly) follow such things.

Business section: Investing ideas
Curious which companies are bucking the low-volume trend?

We created a screen on companies that have a three-month average trading volume above 1 million shares. Then we looked for companies that are trading well above that average and how much the high volume affected share price.

We do this because when increased activity surrounds a stock, it means more people are essentially voting on the stock's value. If prices are moving up while volume is increasing simultaneously, it indicates investors feel the stock has more to price in. When a stock is in an uptrend or downtrend trend but trading volume is declining, it's a sign the trend is losing its momentum.

These companies have been receiving a lot of attention from investors for various reasons -- such as earning surprises, industry trends or breaking news -- do you think they will continue on their current trend? (Click here to access free, interactive tools to analyze these ideas.)
