I don't know what has been happening the past couple days, but this stock is prone to volume spikes at the first of the month and when dividends are paid. They have a great DRIP, but you are going to get price and volume spikes when those funds are used to purchase BOBE stock.
More generally, this stock is subject to weather fluctuations. A good chunk of their profit comes from their sausage operation. I the past year or so they have been recovering from high hog prices.
Also the business has been recovering from some hard times in their restaurant segment. About a year ago they got rid of a unproductive Mexican chain. They also slowed their expansion plans to concentrate on same store sales. This included a new ad campaign and revised menus. Same stores sales have started to increase, so the stock is going up.
I am buying and holding, so I don't care about short term bounces. I have been investing via their drip for a couple of years now. However, if you are a speculator, then watch the weather patterns in the Midwest. Bad weather that drives up feed prices or cuts into restaurant traffic will cause this stock to drop. Recoveries tend to take longer.
IMHO, the recent spike in BOBE is likely due to the fact that the stock tested and successfully broke out above its all time high. The previous high was 21.75 last seen in 4/95. A lot of short to intermediate term folks use trading range breakouts like these to enter into a position (I'm one of 'em!)
