La fine della bolla nelle obbligazioni? Come riposizionare il portafoglio se i tassi di interesse salgono

In due articoli il Wall Street Journal torna sulla possibilità di una bolla nei mercati obbligazionari (e sul rischio che i piccoli investitori ne paghino le spese) e su come prepararsi a un possibile scenario di tassi di interesse in aumento. Secondo il WSJ

The bond market is a bubble, and the little guy is blowing it.
That has been a constant refrain on Wall Street lately, as retail investors poured over $375 billion into bond mutual funds last year and another $230 billion thus far in 2010 (...)
Retail investors certainly don't have a good track record when it comes to buying bond funds en masse. They pumped tens of billions of dollars into them in early 1987, right before rates shot up and bonds got pounded; the same thing happened in 1994.
But this time around, retail investors have had no choice if they wanted to earn income.(...)
Since spring, the Fed has essentially stopped buying, but it still holds $2.04 trillion in bonds, up $1.5 trillion from the end of 2008. This massive buying, nearly triple the amount that retail investors added to bond funds over the same period, has helped drive interest rates to near-record lows.
Meanwhile, foreign investors have bought $373 billion of Treasury debt so far this year, or nearly 60% more than U.S. households have put into all bond funds combined.
If anybody is to blame for a bond bubble, it isn't Joe Schmo; it's Uncle Sam, with some help from overseas.


Così i piccoli investitori rischiano di ritrovarsi nei guai se, magari dopo un'ultima breve fase di quantitative easing (ampiamente già scontata sia dai mercati valutari che, soprattutto, da quelli obbligazionari) l'economia U.S.A. si riprendesse un po', l'inflazione aumentasse e con questa i tassi di interesse. A un lunghissimo mercato toro per le obbligazioni potrebbe seguire una fase prolungata di rialzo dei tassi. Scrive il WSJ

Is it time to start positioning your portfolio for rising rates? (...) 
Bond yields have fallen for most of the past three decades. A $1,000 investment in the U.S. government debt in 1980 would be worth about $12,970 today, according to the Ryan Labs Treasury Composite Index. Treasury prices, which move in the opposite direction of yields, have surged 9.3% this year alone.
Now consider a different era: 1949 through 1979. Over that 30-year span, a $1,000 initial investment in Treasurys would have turned into a far humbler $2,950. That's because yields soared during the period; by 1980 the yield on the 10-year Treasury had reached a record high of nearly 16%.
Given that Treasury yields have since plunged back down to 2.5% or so, how much further can they fall?

Nel breve periodo, se la Fed intraprenderà una nuova fase di quantitative easing i tassi potrebbero scendere ancora un pochino (anche se è difficile immaginarli considerevolmente più bassi con lo yield sulle obbligazioni del Tesoro U.S.A. quinquennali pari all'1.1%, decennali al 2.4% e trentennali al 3.7%).
Ma se gli "ottimisti" (leggi "non catastrofisti") avranno ragione - tra i quali si annovera ad esempio Martin Wolf -  i tassi potrebbero non rimanere così bassi per lungo tempo:

Since the Fed can basically print money, investors would be wise to respect its ability to cause inflation if it desires.
It wouldn't take much of a rise in rates to pose problems for investors. A one-point jump in Treasury yields would translate to a 5% loss for the 10-year Treasury note and a 12% drop for a 30-year Treasury. 

Com'è possibile proteggersi dal rialzo dei tassi di interesse, e magari riuscire anche ad approfittarne? Il WSJ elenca alcune possibilità, accomunate dal focus sul breve periodo, sulla relativa indifferenza ai tassi di interesse e su una più marcata sensibilità alla crescita economica.

How to Play Rising Rates

  • Floating-Rate Debt: Floating-rate loans gained 9.1% from September 1993 through November 1994 as the Federal Reserve raised rates 2.5 percentage points. Advice: Check the credit quality of the fund's portfolio and its use of leverage to ensure you're not adding too many other sources of risk.
  • Dividend-Paying Stocks: Investors pick up an annual yield of 2.6% by buying the Dow for its dividends, compared with the 2.5% yield of the 10-year Treasury note. Advice: Investors can buy a dividend-weighted index fund to get a yield boost—and additional upside if rates rise.
  • High-Yield Bonds: The SPDR Barclays High Yield Bond ETF gained 7.2% during the past four months. Advice: Buy high-yield bond funds with short duration and an average credit rating close to BB—or buy one of three highyield ETFs.
  • Convertible Bonds: Convertible bonds gained 18.1% in the 12 months starting May 2003, as 10-year Treasury yields rose 1.28 percentage points. Advice: Buy a multisector bond fund that has a large portion of its portfolio in convertible bonds.
I cosiddetti junk bonds in passato si sono ben difesi nei periodi di rialzo dei tassi di interesse. Dal punto di vista della valutazione relativa, lo spread attuale di circa il 6% rispetto alle obbligazioni del Tesoro U.S.A. di pari durata è in linea con la media storica e ben superiore al 2.6% dell'estate del 2007, prima della crisi finanziaria. Le obbligazioni convertibili, grazie all'opzione di conversione in azioni, sono molto meno sensibili ai movimenti dei tassi di interesse. 
Le azioni ad alto dividendo sembrano particolarmente attraenti in questo momento di incertezza, poichè dovrebbero garantire una buona protezione nel caso di perdurante inflazione bassa o di leggere deflazione, e rivalutarsi se i tassi aumentassero.Secondo il WSJ 

In 2003, when Treasury yields rose, equity-income stocks outperformed all other income-producing investments, with returns of 31.4%. They gained 7.6% for the 12-months beginning June 2005 when Treasury yields rose 1.22 percentage points. Much of those gains came from stock price appreciation: as bond yields rise investors tend to rotate into faster-growing stocks.
The bond rally has presented relative bargains in dividend-paying stocks. The Dow Jones Industrials have a dividend yield of about 2.6% now, compared with 2.5% for 10-year Treasurys. And dividend payments, like bond yields, tend to rise with inflation.
What's more, the regular dividend payments act as a cushion if stocks fall. "Dividend stocks should do well when yields rise, but also do well in a low-for-longer environment," says Hannes Hofmann, head of U.S. equities at JP Morgan Private Bank.(...)
Investors who want to do it themselves should focus on companies whose dividends are high, but not so high that they can't continue to grow. Since 1984, stocks in the second quintile of the Russell 1000 as ranked by dividend yield have outperformed the other four quintiles as well as companies that don't pay dividends, according to Savita Subramanian, head of quantitative strategy at Bank of America Merrill Lynch. 
Infine non bisogna dimenticarsi delle materie prime e, soprattutto, delle obbligazioni governative inflation-linked come i TIPS. Entrambe queste asset class dovrebbero fornire un'adeguata protezione nel caso di un aumento sostanziale ed improvviso dell'inflazione.

Una bolla nelle obbligazioni? Ma no, è solo che il destino degli USA è diventare come il Giappone!

Con il tasso di interesse sui Treasury a 10 anni che si attesta intorno al 2.7% la controversia sulla bolla o non bolla nel mercato delle obbligazioni ha perso un po' di smalto rispetto a un paio di settimane fa quando i rendimento si aggirava sotto il 2.5%. Vi segnalo ugualmente un articolo e un post sull'argomento che ho trovato interessanti: 
  • Sul Wall Street Journal di lunedì scorso Richard Barley si domanda se il mercato toro ormai trentennale nelle obbligazioni governative non stia volgendo al termine. Secondo Barley potrebbe essere presto per cantare il de profundis per i bonds:
    Sure, there won't be a repeat of the extraordinary capital appreciation of the past 30 years: U.S. 10-year Treasury yields have fallen from nearly 16% in September-October 1981 to just 2.7% today as inflation was quashed and central banks cut rates. More recently, risk aversion has driven yields even lower. As a result, 10-year Treasurys have now outperformed stocks over the last 15 years in the U.S., while corporate bonds have been a better bet than stocks over the last 25 years, according to Deutsche Bank.

    But powerful long-term trends are also helping to fuel the bull market. Aging populations in developed countries are likely to buy more bonds to preserve capital as they head for retirement. The late 1990s U.S. equity bubble coincided with a peak in the share of the U.S. population of high savers aged 35-54, while in Japan the peak arrived in 1990—the high point for stocks in Tokyo, notes Barclays Capital. At the same time, regulators are demanding that financial institutions hold larger buffers of high-quality bonds. Central-bank purchases of bonds for monetary policy purposes are also driving down yields.

    But there are risks around these trends. (...)

    In the near-term, however, bond yields could yet fall further if developed economies follow the Japanese path. And while bonds look rich, developed-market equities don't look cheap (...)
    The cult of the bond is not dead yet.
  • James Montier dedica un post alla questione di una bolla nelle obbligazioni intitolato Bond bubble: a sterile debate on semantics. Secondo Montier non è difficile valutare un'obbligazione: in essence bond valuation is a rather simple process (at least one level). I generally view bonds as having three components: the real yield, expected inflation and an inflation risk premium. 
    The real yield can be measured in the market thanks to inflation-linked bonds. In the US, a 10 year Tip is trading at just under 1%. Expected inflation can be assessed in a variety of ways. We could use surveys, for instance, the Survey of Professional forecasters shows an expected inflation rate of just under 2.5% p.a. over the next decade. In contrast, the nominal bonds minus the TIP yields implies a figure of more like 1.5% p.a. The inflation swap market is implying a 2% p.a. inflation rate over the next ten years.
    The inflation risk premium (a risk premium to compensate for the uncertainty of future inflation) is generally held to be between 25bps and 50bps. Given the uncertainties surrounding the impact of monetary and fiscal policy I’d argue that using the high end of that range seems reasonable. (...)
    Given this ‘parameter’ uncertainty is would be reasonable to say that ‘fair value’ for 10 year bonds is somewhere in the range of 4-5%. 
    A questo punto è chiaro che siccome il rendimento attuale è ben al di sotto del 3% le obbligazioni decennali del Tesoro U.S.A. non sono particolarmente attraenti, tranne se si è convinti che il destino degli Stati Uniti sia di diventare come il Giappone. Montier si spinge oltre e cerca di stimare la probabilità di uno scenario giapponese che il mercato sta scontando con rendimenti così bassi. Utilizzando la tabellina qui sotto Montier conclude che In essence, the market is implying a 70% probability that the US turns Japanese.
