Although we don't believe in timing the market or panicking over market movements, we do like to keep an eye on big changes -- just in case they're material to our investing thesis.

What: Shares of DCT Industrial Trust (NYSE: DCT) rose 10% in early trading before closing up 6.7% for the day and 10.6% for the week.

So what: The move is the latest in an ongoing rally since late August, when the stock fell to a 52-week low of $3.96 a share. My guess is yield chasers with an appetite for this real estate trust's 6.3% dividend payout are driving the gains.

Now what: But whoever it is buying, they're buying big. More than 10.6 million shares traded hands today, nearly triple the average daily trading volume in DCT shares. Do you believe these bulls have it right? Or are you still skeptical? Please weigh in using the comments box below.
