"Annaly Capital (NYSE: NLY) is in the sweet spot," says Steve Sjuggerud in Daily Wealth. He says, "It borrows money at a low interest rate and invests it at a higher rate -- and earns the 'spread'."

"The cost of money is historically low, and it's headed lower. Meanwhile, relative to the cost of money, the return on money is higher than it's ever been.

"The ultimate way trade on this historic discrepancy, for high-returns with very low risk, is through shares of companies like Annaly, which is now s now paying a 16% dividend.

"In the latest-reported quarter, the company borrowed money at 3.5%. (The credit markets have calmed down a bit, so its cost of borrowing should be even lower next quarter.)

"It invests the money in government-guaranteed bonds. You remember how the Treasury bailed out Fannie Mae and Freddie Mac? It wiped out shareholders. But it explicitly guaranteed the bonds.

"In the latest-reported quarter, Annaly earned 5.6% interest on these risk-free bonds. Therefore, it earned a 2.1% spread. If the company uses seven times leverage, a 2.1% spread means a 14.7% return on its money.

"Analysts estimate the company will earn $2.50 per share next year. It pays out essentially all of its earnings in dividends. So that'll be a dividend yield of about 19%. This is ridiculous. An opportunity like this only appears during market turmoil like we're experiencing now.

"This is a historic moment. The difference between the cost of money and the return on money relative to that cost is at the most extreme levels I've seen in my career. Take advantage, and buy stocks like Annaly today."
