Another historic moment to mark on the calendar: The U.S. national debt has eclipsed the entire U.S. economy.

The amount of money the federal government owes to its creditors, including the money owed to itself, such as IOUs to government retirement, social security and other programs, has hit $15.23 trillion.

The total money owed is equivalent to the estimated value of all goods and services the U.S. economy produces in a year, an amount valued at $15.17 trillion as of September. This comes across as a troubling sign.

"Long-term projections suggest the debt will continue to grow faster than the economy, which would have to expand by at least 6% a year to keep pace," reports USA TODAY.

The U.S. joins five other advanced nations with debt greater than their economies: Greece, Iceland, Italy, Japan, and Portugal.

Perceptions of debt
National debt can be a difficult thing to understand. The government owes approximately $4.7 trillion of the debt to itself, and that payment is less of an immediate issue.

By discounting the U.S. government to U.S. government debt, the debt is roughly $10.5 trillion, about 70% of the national economy. This is still very high.

The size of the debt also minimizes the importance of Congress' August agreement to cut $1 trillion from federal agencies over 10 years. An additional $1.2 trillion in automatic spending cuts will begin next year if Congress cannot agree to better ways to curb more spending.

Business section: Investing ideas
Bearish investors are worried that debt growth will outpace economic growth. With this in mind, we wanted to take a closer look at low-debt companies that are expected to grow rapidly over the next five years.

As a start, we collected data on institutional money flows, and identified low-debt, high-growth stocks that have seen significant buying from big money managers over the last three months.

To further refine the quality of the list, we collected data on insider transactions and identified a list of stocks that have seen significant insider buying over the last six months.

Theoretically, insiders know more about their companies than anyone else. So if they're using their own cash to buy the shares of their employers, you'd better pay close attention.

Insider executives and big money managers, aka "smart money investors," are optimistic about the outlook of these companies -- do you agree? (Click here to access free, interactive tools to analyze these ideas.)
