What: Shares of trucking logistics company YRC Worldwide Inc. (NASDAQ:YRCW) jumped as much as 18% today after reporting second-quarter earnings results. At 12:05 p.m. EDT shares were still up 15.5%.

So what: Operating revenue fell 4% in the quarter to $1,207.6 million and net income fell $1.1 million to $30.3 million, or $0.83 per share, in the quarter. But analysts had expected only $0.51 per share in earnings, and investors had lowered expectations for the year as well. So, it's not growth that's driving the stock today, but rather beating already low expectations. 

Now what: The macro environment isn't particularly strong for the trucking industry, and that's weighing on YRC Worldwide. But the company can control costs and what it charges for value-added services, which is what's keeping the bottom line strong for now. I would like to see some more consistent demand growth before jumping into shares, but for now YRC Worldwide's steady results should keep investors from pushing the stock much lower, which is a concern given weak performance so far in 2016.
