As the year comes to a close, it's helpful to look back at what happened to the stocks you follow. With a highly visible company like General Motors (NYSE: GM), which is mentioned in the business news nearly every day, it's easy to get caught up in a short-term view of events -- but the longer-term perspective is what really matters when judging an investment.

Plain and simple, 2011 was a year of consolidation for the General. With his management team finally stable after a long period of churn and turmoil, GM CEO Dan Akerson was able to start implementing his long-term vision for America's largest automaker. But it will be several years before his vision becomes a reality, and the rough performance of GM's shares reflected that, as economic conditions continued to pose a challenge for the company.

General Motors' key statistics
The fundamentals weren't bad, especially given GM's recent history and challenging economic headwinds around the world, but there's considerable room for improvement:

Ouch. Revenues are up, but earnings are down as margins have come under pressure -- and the stock price got positively hammered, despite $4.57 in earnings per share over the last 12 months. So what happened?

Why the stock got clobbered
GM's new managers have actually executed quite well for the most part -- better than some of us expected -- but the company faced a number of headwinds in 2011:

  • Global headwinds. The white-hot Chinese auto market cooled considerably in 2011, though GM -- the market leader, via several joint ventures -- still managed to pull out decent sales growth. More importantly, the General's long-troubled European operation hit a crisis point as the European economy sagged, losing money in the most recent quarter and prompting a high-level review likely to lead to drastic action (a major restructuring, at least) early next year.
  • Pension liability. Despite GM's low debt, $30-billion-plus cash hoard, and respectable profits, many institutional investors have shied away from the stock out of concerns for GM's pension liabilities, which could -- some have speculated -- eat up much of that cash hoard over the next couple of years. CFO Dan Ammann recently said the company now estimates its liability at $8.7 billion and has promised to present more detail on the state of those obligations when GM's year-end results are revealed early in 2012.
  • Product line still a mixed bag. Rival Ford (NYSE: F) has managed to overhaul most of its product portfolio in recent years, creating a streamlined global lineup of vehicles that compete well with top rivals Toyota (NYSE: TM) and Honda (NYSE: HMC) while reducing ongoing development costs and improving margins. GM is determined to follow Ford's lead, but its product-development efforts were set back significantly while the company fought for its life in the years leading up to the economic crisis. GM's newest products are mostly top-notch (including the Chevy Volt, recent troubles notwithstanding) but many product-line gaps remain -- gaps that, in some cases, may not be filled until mid-decade. Meanwhile, heavy investment in developing new products and improving existing ones will continue to eat dollars for a while.

Long story short: GM is doing a lot of things right, but a lot of work remains -- and like any cyclical stock, macroeconomic expectations will have a big effect on its share price. There's a lot to like about GM as a value buy here, but investors will need to be patient -- and to stay informed as 2012 unfolds.

A convincing resolution of the pension issue and a restoration of GM's dividend would do a lot to improve the stock's prospects with institutional investors. While it's possible we'll see the dividend return in 2012, you don't have to wait to put the power of reinvested dividends to work in your portfolio.
