Does anyone know of any reason besides just normal stock market hops, skips and jumps, why BJRI is up 6.7% today?

I'm thinking about picking up a few more shares of this company. Here is why.

They only have something like 116 restaurants at the moment. I've read where they say they'd like to have 300 and I think Tom E has said he can see them having many more than that.

There are no BJ's in the state I live in and as of yet, I've never been to one. I have dug around on their website and they seem to have a menu that I'd like to try sometime.

I'm actually debating buying shares in one stock out of 5 companies. Besides BJRI, I'm thinking about Panera Bread, Amazon, Whole Food Market and 3D Systems, DDD.

I may purchase small, roughly $200 positions, in 2 of these 5 companies within the next few days. Depending on how the share prices look in a few days may decide what stocks I chose to make a purchase in.

I currently hold small positions already in BJRI and AMZN, but no positions yet in WFM, PNRA and DDD.

We'll see what I do this week and if plans go accordingly, what new small positions I may purchase in a month.
