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 consumer goods maker Jarden (NYSE: JAH) jumped as much as 10% today after the company announced increased revenue guidance.

So what: The company now expects fourth-quarter revenue to be between $1.73 billion and $1.74 billion, slightly beating estimates of $1.72 billion in revenue. The company also announced a tender offer to buy back $500 million in shares, an acceleration of an existing buyback program. Management expects to buy shares between $30 and $33 each.

Now what: With more than $800 million in cash, the company has more than enough to fund the share repurchase. Even after today's bump, shares trade at just 8.7 times forward earnings, so I think the value is strong right now. I don't usually like to buy on a day a stock jumps like this, but I think the good news from Jarden is too good to pass up.
