With ever growing uncertainty whether our economy will face inflation or deflation in the months to come given recent government spending, what is certain is that no one wants to see their fixed income lose purchasing power. Unlike most bonds that pay out a fixed dollar amount in interest, treasury inflation protected bonds (TIPs) pay out a fixed amount over the consumer-price index (CPI), making them a popular choice for investor anticipating the economy to experience inflation. If inflation is higher than projected, the government adds to your principal on a TIP and makes up the difference!

Not only does owning TIPs allow one to keep up with monthly bills that are increasing in step with inflation, they are an important asset class to consider when determining an asset allocation strategy. TIPs enable one to further diversify a portfolio. Bonds are ideal for those not able to stomach much risk and TIPs in particular protect one's fixed income from eroding.

Why is China loading up on US Treasuries? At first glance that seems strange because the dollar keeps falling. Doesn't a falling dollar mean that inflation is on the way? Not necessarily. The Labor Department reported that prices of imported goods fell 15% in August from a year ago, this after a 19.2% drop in July. These numbers are telling us that there is no inflation coming in the near future. The Fed has plenty of wiggle room. It can afford to keep interest rates at historic lows.

So then why is the dollar weak? We know what the answer is. The Fed has pledged $12 trillion dollars to bail out the bankers, housing and the mortgage market, just to name a few areas where the money is going. Then too, we have sky high deficits. The current account deficit will rise to 3.2% of GDP in 2010 and 3.5% in 2011.

"The markets are littered with compelling buying opportunities that may be the best we see in a generation," says Keith Fitz-Gerald.

In The Money Map Report, he looks at a trio of income ETFs -- one focused on Treasury inflation protected securities, one invested in muni bonds, and one that buys high yield corporates.

"We are holding three positions in our portfolio which we believe can be bought with new money. First, we suggest iShares Lehman TIPS Bond ETF (NYSE: TIP). The 10 year TIPS' yield is 2.23% versus 2.40% for 10 year Treasuries.

The US Treasury expects to fund $1,900 billion in net borrowing this year. To accomplish this, it is bringing back the seven-year note and the three-year note. Traders expect that the Treasury will issue each denomination of notes and bonds each month. To say the least, this kind of financing is unprecedented. The problem will be: who will buy all these securities?

This strategy went from being a modestly successful trade through October to a hero-sized trade in the past 45 days.

The Fed funds rate, the most widely followed interest rate the banks charge each other for overnight lending, topped out in August 2006, at 5.25%.

When the Fed started easing rates thereafter, no one at the economic think tanks forecasted anything close to what we are seeing today (namely a Fed funds rate of zero to 0.25% -- a decline of a full 5% in 17 months).

The decline in rates started out so orderly and coordinated that it seemed almost too good to be true, and the Dow Jones Industrial Average hit an all-time high, topping 14,000 for the first time in July 2007.

However, the quarter-point cuts gave way to a three-quarter-point cut, or 75 basis points, on Jan. 22, 2008, signaling that the Fed was seeing a material breakdown in the credit and housing markets. Following that seemingly radical rate cut, just eight days later on Jan. 30, the Fed again slashed the Fed funds rate by another half point, or 50 basis points, to 3%.

From there Bernanke & Co. held steady for a couple months to see if any good would come of their efforts.

When evidence of further erosion in the credit markets surfaced with the impending collapse of Fannie Mae (NYSE: FNM), Freddie Mac (NYSE: FRE), Indy Mac, Bear Streans and Lehman Brothers (OTC: LEHMQ), the Fed lopped another three-quarters of a point off the Fed funds rate, taking it down to 2.25% on March 18.

That was considered the absolute floor at the time, a level that would stick. But that wasn't the case.

For most investors and traders, 2008 was a tough year. But while many people saw their portfolio take a merciless beating and watched their retirement vanish into thin air, there were a select few who made a killing.

In fact, if you had been on the right side of any of these bets, you could have banked enough dough to make up for your losses and then some.

Here are five trades everyone wishes they had made in 2008:

#1 Shorting 'Chindia' the day after New Year's: The Chindia experience peaked in Beijing with Michael Phelps, and the market knew it would a year and a day before the Closing Ceremonies.

#2 Getting long and staying long the 30-year Treasury bond: This strategy went from being a modestly successful trade through October to a hero-sized trade in the past 45 days.

#3 Shorting oil on the Fourth of July: The drop in oil prices has been nothing short of unbelievable. Those that had the fortitude to short crude in early July (and had the stones to stay with that trade) made a killing.

#4 Buying DryShips (DRYS) at the November low: Following its meteoric rise to $116, the stock careened all the way down to $3. But if you went long then, you saw the share price quadruple in less than a month.

#5 Shorting 'too big to fail' Fannie and Freddie: This shorting strategy defied all odds and pretty much defined the year for the stock market.

"The latest annual rate of inflation measured from last July to this July was 5.6%, the largest annual gain since way back in January 1991," observes Alexander Green.

Here, the investment director for the industry-leading The Oxford Club suggests that investors consider the iShares Lehman TIPS Bond Fund (ASE: TIP), noting, "This is a great way to buy a diversified portfolio of inflation-adjusted Treasuries and track them quite easily."

"The latest consumer price index figures were a bit of a shock; the annual rate of inflation measured from last July to this July was 5.6%, the largest annual gain since way back in January 1991.

"Despite these horrendous inflation figures, gold, mining shares and other inflation-sensitive indicators did nothing – or even fell. What gives?

"Remember that the market is always looking forward, not back. Investors are always more concerned with what lies ahead than what happened in the recent past. Next month or next year may be a different story entirely.

"That's why every investor should have a hedge in his portfolio, like inflation-adjusted Treasuries. These bonds are unique in the investment world. They are the only investment guaranteed to beat inflation. And they are great portfolio diversifiers. They don't march in step with either stocks or bonds.
