One of the great maxims of traders and Wall Street pros is to follow the "smart money."

I'm not much for the thesis that institutional shoppers tend to make smarter investing decisions, but many of you who've read my ruminations on insider buying say you'd also like to know how the Big Money is betting. Your wish is my command.

Next up: US Airways (NYSE: LCC). Are institutions bullish or bearish when it comes to this suddenly profitable legacy airline?

Fools couldn't be more disapproving of most airline stocks, but they reserve a particularly virulent dislike for US Airways. Are you really surprised? This, after all, is the company that made the bathroom sink the only source of free water on domestic flights two years ago.

CEO Doug Parker took ridicule for the move, but economics said it had to be done. A number of carriers now charge for what were once basic amenities. In the case of US Airways, a long history of low or negative returns on capital dictated dramatic action.

This week, Parker got a chance to celebrate the results of acting boldly. US Airways reported its first profitable fourth quarter since 2006. Revenue rose 10.7% to $2.9 billion, resulting in $0.17 in per-share earnings. Analysts were expecting just $0.06 per share.

Does the beat mean US Airways is a buy? Big Money investors have backed off their buying in recent months, but on a net basis they've added to their position in the carrier since the end of 2009.

Meanwhile, some Fools sense value in the shares at current levels. Four of the seven investors to rate the stock in CAPS over the past week say it will outperform the market, including All-Star performer wcwhiner.

But judging from this table, the skeptics may be right. United Continental has by far the best ownership profile. Only 60% of institutions own the stock, which means there's plenty of room remaining for Big Money buyers.

By contrast, US Airways has already sold 87% of itself to institutional investors. Their next most likely move is to sell. Despite my problems with the carrier's Q4 report, I'd much rather have money in UAL right now.
