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 workforce accommodation specialist Civeo Corp (NYSE:CVEO) fell as much as 19% today after the company reported earnings for the fourth quarter of 2014.

So what: Revenue fell 15% to $219.7 million and net income adjusted for one-time charges was $18.0 million, or $0.19 per share. Results actually beat the $205.1 million in revenue and $0.13 in earnings analysts expected, but guidance is what hit the stock today.  

Management said it expects revenue in 2015 to be between $520 million and $560 million with EBITDA falling between $130 million and $150 million. That compares to $942.9 million in revenue in 2014 and EBITDA of $339.8 million.

Now what: Clearly the mining market in Australia and the oil sands in Canada are going to struggle with low commodity and oil prices, which is hurting demand long-term. With $775 million in debt the oil market needs to recover significantly for Civeo to be a solid investment. I think low oil prices are going to persist for at least the next year and there's little likelihood of companies increasing capital spending, particularly in Canadian oil sands. Management's efforts to cut costs are positive, but I need to see much more improvement in the oil markets than I see today to jump into Civeo.
