The case for converts

 


Convertible bonds are hybrid structures which claim both equity and debt like features. As such, convertible bond investors are exposing themselves to the volatility of the underlying equity (and the market it trades in) as well as its credit features (and overall spreads). Because of the embedded option, the value of the bond should increase as volatility picks up.

It’s unfortunately not that simple. Increased volatility in the equity markets is more often than not accompanied by some form of spread widening (i.e. repricing of risk all across the board) and ultimately acts as a competing force driving down the price of the bond. This summer for instance, saw convertibles trade more like credit than equity options. Even though equity volatility spiked in August, the weakness in broader credit markets adversely impacted convertibles.

The summer of 2002, on the other hand, offered a very different scenario. Enron, Worldcom, Adelphia and Tyco to name few led the credit markets into one of the largest corrections it had seen. Convertible bond managers on the other hand thrived on the volatility and saved the day. Och Ziff was in such difficulty with its high yield exposure in the summer of ’02 that had there not been for their converts book, we certainly wouldn’t be talking about an IPO of the firm. The general impression of the fact that convertible bond managers “could do no wrong” led to a “wall of liquidity that came to strategy”, ultimately sealing its faith and lack of returns.

In any event, thanks to the development of credit derivatives, market participants can more readily focus on the vol component whilst limiting their exposure to each issuer’s credit risk. Although the US converts market is adequately priced it could offer great opportunities if volatility were to pick up.


Volatility and its impact on a Fund of Hedge Fund portfolio

The risk landscape is changing and 2007 appears to be a turning point:

  • US housing deflationary path plus global contagion.

  • Growth slowdown (below 2% in the State, recession fears, decoupling Europe-BRIC, US consumer considered “fragile”)

  • Statistical systems are bad at identifying turning points

  • Risk pricing all across the board (volatilities, spreads, steepening of curves along time horizons)

  • Reduction in currency carry trades towards individual yield curves

  • Tight liquidity conditions to continue in structured finance space until prices re-establish themselves by market making

  • Central banks to err on the side of reflationary policies with lower rates at the expense of inflation with competitive currencies “debasement peg” – US$ crash

  • High risk of policy errors.

In the end, fund of funds can suffer due to these high uncertainties and increase volatility. The following chart clearly shows how the negative data points in a multi strategy fund of hedge funds are highly correlated to spikes in volatility. Owning long vol strategies such as a convertible bond fund has never been this important in my view.

We’ve already started seeing signs of this in the markets. In painfully appropriate fashion, Friday October 19 marked the 20th anniversary of Black Monday, as the S&P 500, the Dow and the Nasdaq all sold off around –2.6%, the biggest daily drop since early August. The events of the past week have also offered investors some pause: Bonds rallied, spreads widened, oil continued to rise: Nymex futures rose another +5.9% last week, topping US$93/bbl. The Yen strengthened and hile still well within the 110-120¥/US$ range, the Yen did strengthen by +2.1% last week (and is now trading around ¥115).

It seems the market is not yet convinced that the Fed’s recent liquidity injections and the 25bp rate cut will be sufficient to stem the rut in the financial markets. In addition, the new “Super SIV” bail-out fund has also failed to raise investors’ confidence. And in turn, the futures market now clearly implies that, with headwinds still on the horizon, the Fed will be inclined to make further rate cuts—contracts now imply, with 92% certainty, that the Fed will cut another 25bp on October 31st (upping the odds from 70% 10 days ago) and will likely cut again after that.

“When Wall Street's banquet table is tipped over, the Fed cannot stop the dishes from falling—all they can do is prepare to clear up the mess once the china breaks. Shooting off anything more than a 25bp rate cut at a time like this would be a waste of the Fed's ammunition. Having said that, many investors may well be expecting a more dramatic Fed move, and thus the markets could drop pretty steeply if rates are only cut -25bp.” Gavekal have commented in a recent note.


Why convertible bond arbitrageurs make sense at this stage.

The summer’s weakness in the convertible market has produced some opportunities. “The realized losses and selling by convertible investors (i.e. some hedge funds have reduced their convertible bond exposure) have clearly cheapened prices with the high volatility and credit sensitive names displaying the highest potential” claims David Rich, CIO of Amida Partners. Amida is a multi strategy hedge fund based in New York with a dedicated converts trader who looks at the strategy.

“According to HFR, convertible arbitrage posted a positive 1.66% return in September helped in large part by the rally in credit spreads which was partially offset by falling equity volatility. Amida had acquired several new convertible positions before the Fed cur rates. At this stage Amida maintains a disciplined approach in convertibles that is best summed up as trying to identify pockets of opportunity in a market that, as a whole, is trading at fair value” adds David Rich.

Some names have cheap embedded options and are good buys in the present environment. They can only get more attractive if volatility were to increase form current levels.

  • Credit default swaps trade LIBOR + 680 bps, convertible bonds imply 30% volatility, comparable listed LEAPs are trading 50-55% implied volatility.
  • Static unannualized return is 11.4% if AMD converges to fair value.
  • Total one-year return on capital of 24.0% if gamma trading stock and realizing 40% volatility.
  • Crosses par 6% with a 46% premium (issued at 6% + 100%).
  • 7.69 years of call protection.
  • Senior debt trading well below par value (84%).
  • Matures 2015.

After the liquidity/credit/structured product crisis drove markets to their lows in mid-August, a pronounced V-shaped recovery was formed as investors went on an impressive buying spree. As a result, equities are no longer undervalued, which was one of the driving factors of the recovery rally. “Near term, we see the current earnings season as offering quite a bit of volatility on a name by name basis” states Jean-Pierre Latrille who runs the convert book for Amida alongside David Rich. He goes on to add “Looking ahead, we suspect the market will become increasingly driven by earnings, and any stocks with downside earnings revisions will risk being cut from portfolios and punished severely. Merrill Lynch last week is a good example with Medtronic (MDT) also collapsing on negative news flow. “

Amida have several analysts that follow companies in their converts universe trying to gauge the potential of missing eps when they report. “It’s very important to have the right people in place to try and find names that will offer good opportunities for gamma extraction” opines Jean-Pierre Latrille of Amida. “this will be a big driver of alpha going forward”.

“Convertible issuance slowed significantly in September to $1.9Bln. However the quality of the new deals improved versus prior months. The three largest issues for Equinix, General Cable, and USEC all improved 2 to 3 points from issue. Amida participated in all 3 offerings” adds Jean-Pierre Latrille and goes on to conclude “I would also add that while you may be buying “fair” vol in converts, you do have the advantage that the vast majority of convertible issues have dividend and takeover protection which makes them superior to listed options.“

Of Greeks and Men.

 

For the past 40 years, scholars have worked hard to render the task of comparing funds easier. Following the demand from investors to be able to compare apples to apples, serious mathematical skills have been deployed in order to find the most significant means of achieving an absolute measure of fund manager added value.

“With the globalization of hedge fund offerings leading to a larger community of investors, this “rear view mirror” statistical method has been deemed to give the best measure of return as well as risk embedded in a fund managers track record, and hence a manager’s investment process” states Sven Miserey, a former credit portfolio manager with GLG and currently Managing Director of Capital Advisory Partners, a London based firm who specializes in operational due diligence. He then goes on to add “unfortunately, before the advent of published VaR, a limited number of very noticeable hiccups occurred. The visibility of negative performances at these times, coupled with the paranoia surrounding potential blow-ups, has left investors somewhat concerned about their investment decisions.”

The most inherent risk investors face is in the investment process of their chosen fund managers. Deviation from the advertised investment process poses much more of a risk to the forward performance of the fund and the statistical risk/return analysis of past performance only monitors this historically.

Fund managers, today, follow a prescribed number of guidelines in their marketing material and prospectus to promote the idea of potential ongoing replication of performances. “Would the investor really feel comfortable trusting his money to the best punter of the street, or be able to defend his investment decisions based on knowledge of rigorous investment processes” adds Miserey.

Reading through the lines of a prospectus and translating the verbal presentation made by fund managers today is becoming more and more complicated to investors, who resort to placing the considered fund inside of a management style box and relying on the Greeks to justify investment decisions. The first 4 steps are usually the following:

  • First analysis: annualised performance – standard deviation;

  • Second analysis: annualised performance – max draw down period;

  • Third analysis: Sharpe ratio to compare the out-performance of the fund to the benchmark (usually risk free interest rates) with a volatility adjustment;

  • Fourth analysis: information ratio which analyses the alpha generated by each unit of capital at risk versus the fund’s benchmark (any deviation from the benchmark is a risk and can be calculated).

Aside for these four points, new performance measures, which some academics claim are better suited for alternative investments, are gaining acceptance, demonstrating the interest of market participants in rationalising the performance evaluation and attribution process.

Indeed, Sharpe ratios use standard deviation as a measure of risk and as such don’t seem to distinguish between good and bad volatility. Therefore the concept of downward volatility and Omega ratios has started gaining ground. “This simple measure is obtained by dividing the cumulative probability of observing returns above a given threshold by the cumulative probability of observing losses (returns below this threshold), therefore Omega constitutes a performance measure that takes both reward and risk into account and that can be used to rank asset performance as usually done with the Sharpe or the Sortino ratio” opine Favre-Bulle and Pasche in one of their research notes. “[We] find that Omega provides a more efficient frontier than those obtained in conventional settings even if returns are normally distributed.”

“In some instances it may act as a good measure and act as a valid way of classifying hedge funds but unfortunately it has value only if you have 200 + data points and the hedge fund manager’s investment process never changes throughout time. Furthermore, you also need to assume markets are recurrent and hedge fund managers don’t learn from their experience” comments Miserey and adds “At this time it seems important to go back to what a manager actually does with your money. Before delving into risk specifics, two points need to be addressed.”

There are 2 main points Capital Advisory feel investors should focus on:

  • First and foremost, how serious is the system a manager uses to initiate trades. How much of it can be replicated and how much is based on the trader’s “feel” for the market. If you want to utilise past performances as a measure of insight into the potential in the future, trade initiation should be your first question.

  • Second, how is the profit and loss of each position managed? Would you toss a coin (1:1) and be content to earn 75 cents for each dollar you bet? A fund manager who is taking bets where his probability of being right is only 10% but makes 20 dollars for each dollar at risk will eventually deliver consistent returns to his investors. Too often the actual money management gets put aside (and more specifically so in abnormal situations).

“Such cornerstones have been set aside in favour of statistical analysis of the prior track record. Isn’t it time to alleviate the paranoia of hedge fund investments by going back to what it is exactly your fund manager is doing with your money? Due diligence should continue the Greek alphabet research which gives amazing insight to risk, but return to the questioning board regarding the persistency of investment processes” concludes Miserey.

The second wave by Gavekal Research

 
 


Making short-term predictions about equity markets is mostly a mug’s game, while making very long-term forecasts is relatively easy. The problem thus becomes the medium-term (i.e. one year) outlook. And this medium-term outlook for US equity markets is, today, as hazy as we can remember it.

As all of our readers know, we experienced a somewhat vicious correction this summer. And, this summer’s correction was very different from those experienced in recent years. Indeed, corrections from 2003 through 2006 were related to inflation expectations flaring up, causing the bond market to get a little ragged and the market to worry about future rate hikes from central banks. The August correction, in the wake of the sub-prime crisis, felt to us a lot more like a “growth scare”. And, sure enough, the US has been slowing for over a year, under the weight of the housing downturn. This summer, it became clear that other G-7 economies were also slowing:

With the growth slowdown, we suspected that the markets would go through some kind of “de-leveraging” process and that, consequently, at least as far as “developed” markets were concerned, the near-term upside would remain limited to previous highs. We wrote as much earlier this summer. We explained that the surge in net margin debt was putting the market in a precarious position and, quite possibly, risking a liquidity disruption (or, even worse, a full-blown crisis).

1-The Market Levers, and Delevers
Let us explain what we mean with a few charts. In the chart below, net margin debt simply represents margin debits minus margin credits. When net margin debt rises, it means that investors are levered long. Off the summer 2006 lows, the market staged a fantastic move—on the back of a lot of leverage. In fact, the only time we have ever witnessed such an increase in leverage was following the LTCM low in 1998 that extended into the March 2000 peak and into the NASDAQ peak.

GaveKal Equity Strategy
Net margin debt has dropped from $80 billion to zero in the last month.

Unfortunately, in the last month, net margin debt has gone from positive US$80 billion to zero. The last time we witnessed such a rapid drop was in the fall of 2000, as market participants gradually realized that the economy was heading into a recession, and as banks tightened credit available to corporates.

Yet, interestingly, despite this massive deleveraging, US indices are still close to all time highs. So who is doing all the buying? One possible explanation is that, along with the deleveraging, we have seen a big drop in the amount of shares sold short on the NYSE. In other words, people are simply curtailing their books (reducing the leverage and buying back their shorts). The chart below shows the number of shares short against the monthly volume of the NYSE. This possible explanation is further confirmed by the big drop in volume.

To cover their shorts,
short sellers have been buying stock from the guys who are selling
to reduce their margin positions…

This is not a backdrop of strength—but it will set up a better buying opportunity.

The internal market dynamics seem to point to a situation where investors have been buying back stocks to cover their shorts from investors selling stock to reduce their margin positions. This is hardly a backdrop of strength, though it is a cleansing process which should set up a great buying opportunity.

2-So What Now?
The SP500 reached old-time highs of approximately 1550 on October 11 but, since then, seems to have begun a new down leg. Interestingly, on or around that day, the liquidity environment made a negative reversal, too. This raises the question: Are we now entering a second phase of a liquidity contraction? A number of liquidity indicators are, unfortunately, pointing that way.

First, in recent weeks, the Euro/Yen cross peaked and reversed.

The Euro/Yen cross recently reversed.

Secondly, commercial paper spreads are once again widening between financial and non-financial paper.

Commercial paper spreads are widening again.

Thirdly, it looks like the VIX has begun another spike and is dragging with it credit spreads. Note the upturn in BAA spreads in the last few weeks.

The VIX has spiked.

Fourthly, swap spreads are widening back out again as well.

Swap spreads are also growing.

We also like to look at the relative strength of the SP500 against the VIX for a feeling of risk/reward, and we feel more confident when the SP500 rises relative to the VIX. Unfortunately, on this ratio, we seem to have entered another down leg here.

While we prefer to see the S&P 500 rising relative to the VIX,
it has fallen through its moving averages again.

Worryingly, we can also observe a deterioration in the breadth of the market, as this second-wave liquidity setback started to hit two weeks ago. Here we see NYSE net advances, 20-day moving average having fallen from near 400 back to around 100.

NYSE net advances have fallen to 100 from 400 in just a couple of weeks.

The NYSE cumulative net advancing volume shows the same pattern.

Advancing volume is also weakening.

Another signal we do not like is a divergence between the trend in the CBOE put/call ratios and the VIX. Such a divergence started to appear a couple of weeks ago, and this gave us pause. A rising VIX and falling put/call ratio is a warning sign, and the gap usually closes with the put/call ratio moving. Sure enough, in the last couple of weeks, the turn in the VIX has finally caused the put/call ratio to reverse.

Warning: The VIX is rising, while the put/call ratio is falling.

If we bring together the trend of the put/call ratio and the SP500, we come up with the chart below. In the chart, we also draw a trend-line of the put/call ratio and one standard deviation lines around that trend. The put/call dipped through one standard deviation on the downside and has now reversed.

In fact, the put/call ratio recently fell more than one standard deviation from its
historical trend. (It has since rebounded slightly)


3-From the Markets to the Real Economy

With the surge in MZM in the last few weeks, it is hard to argue that money isn’t plentiful—the problem is that it may be more difficult to come by (this has happened time and again in Japan over the past 15 years). With that in mind, we worry that disruptions in the credit markets are working their way into the real economy. Housing, the epicenter of concern in the US, looks like it has been negatively affected by the credit markets. Last week we got the latest NAHB survey results and data on existing home sales was released today. These charts show that the housing slowdown is accelerating on the downside, catalyzed by concerns in the mortgage market.

While money may be plentiful, it is certainly not as accessible as it once was.
Concerns in the mortgage market are contributing to the deterioration in the US housing market.

Concurrently, oil prices have risen through $85 a barrel and there are still more questions than answers with respect to how and when SIVs will be rescued. This, no doubt, is related to the huge foreign selling of US assets in the last month.

Rising oil and uncertainty contributed to the large drop in net foreign security purchases.

And, despite a 50 bp cut in rates, we still don’t see the FED working very hard to stimulate the economy. In fact, on a one quarter annualized rate of change basis, the monetary base—in nominal terms—is basically not growing.

And the FED hasn’t done much more to get things going—
growth in the monetary base is nearly zero

.

As we have said, inflation is about the last thing we should be worrying about right now. With the 10-year bond yields breaking out on the downside today (4.31% as we write), the bond markets are obviously increasingly concerned with growth.

Yields continue to fall, raising further concern about the US economy’s capacity to grow.
The markets appear to have finally realized the growing risk to the economy…

It seems that a second wave of the liquidity crisis may be unfolding. Perhaps we are simply overreacting after this summer’s challenging and testing times. Nevertheless, as far as developed equity markets are concerned, we would rather put some powder on the sideline until new highs are decisively broken.

Are we facing a second wave in this liquidity crisis?
