A look under the hood shows that many core bond funds have continued their quest for income.
We've been watching and discussing the trend for some time, and it doesn't appear that core bond fund managers are letting up. With Treasury yields at rock-bottom, and worry about the eventuality of rising rates gripping many investors, there are plenty of funds that continue to tilt away from the broad-market investment-grade bellwether, the Barclays U.S. Aggregate Bond Index.
The data is tricky to pin down, but the picture is clear. We've written in the past about how much funds' correlations have drifted away from the Barclays index. One reason for this is the divergence between the performance of certain subsectors--think corporates and agency mortgages--and the Treasury-heavy index itself. But there's also continued evidence that many--though certainly not all--managers are treading lightly in Treasuries. Indeed, while it's not unusual for funds in the intermediate-term-bond category to underweight Treasury and agency bonds, they have, on average, about 30% exposure to those sectors versus more than 46% in the Barclays U.S. Aggregate Bond Index. Typical funds' agency mortgage stakes are also below those of the index. That leaves considerable room for other sectors that are either lightly represented in the index, or not at all.
We thought we'd take a look at some of these sectors and why managers continue to favor them in portfolios.
This is the most conventional route that most managers are taking when it comes to getting away from their benchmarks. Corporates account for roughly 22% of the Barclays Aggregate--which reflects market issuance--and numerous funds have bumped up their allocations to the sector. Some managers are even more adventurous; we've seen anecdotal evidence of more high-yield debt sneaking into core portfolios as well. The reasons are pretty straightforward. Company balance sheets are about as healthy as they've been for many years, with cash holdings reported to be in the trillion-dollar range in the U.S., and default rates are at multiyear lows.
The problem is that by nearly any measure, yields--and their spreads above Treasuries--for investment-grade corporates are near or below their multiyear lows. On average, they clocked in around 1.3 percentage points above comparable Treasuries around the middle of April 2013. It's no secret how they got there, of course. In addition to the aforementioned attractive fundamentals, buying has been strongly encouraged by central bank policies, not least of which have been the Federal Reserve's quantitative easing programs. They have played a major role in suppressing agency mortgage and Treasury yields, which has pushed investors to take on more credit risk in search of more yield.

This one may surprise folks who haven't looked inside their portfolios for a while. The CMBS market represents only a modest 1.8% of the Barclays U.S. Aggregate Bond Index, but we've been seeing some meaningfully higher allocations to the sector as of late. BlackRock Core Bond
The reasons why managers have favored the sector overlap somewhat with those underpinning the popularity of investment-grade corporates, including central bank policies and investor appetite for higher yields. More specifically, though, there are technical and structural reasons behind the sector's appeal. There have been new private-label (as opposed to agency-backed) CMBS deals underwritten in recent years, but net supply of available securities has been shrinking. JPMorgan
It's unusual to see emerging markets take up quite as large an allocation as other spread sectors in core funds, but the trend of holding them has certainly gained acceptance. For example, as of March 31, PIMCO Total Return
