Fundamental analysis goes to the heart of stock selection, but when the market is driven by macroeconomic or political considerationsthe situation todayit works less well.
Most stocks continued to rise and fall in tandem in October, whether they were newly discovered traditional bargains or casualties of the European sovereign-debt crisis and US fiscal woes. Stock-pair correlations among global stocks were in the 0.5 range at the end of October, versus a norm of less than 0.2 (Display).
But dig down a layer, and youll find that the returns for certain stock characteristicssuch as their valuations, price trends, earnings-growth trajectories, analysts earnings revisions and profitabilitywere weakly correlated.
During the early days of the 2008 financial crisis, these so-called return factors, like the stock correlations themselves, tended to march to the same tune. But over the past couple of years, these factors have instead been marching to their own drummersmeaning they have been far less correlated than usual.
This may seem to suggest that there is ample opportunity to outperform by selecting the best-performing factors. But such an endeavor is fraught with risk, because factor leadership can change abruptlyas it did this year.
Investors were so anxious during the first nine months of the year that most of the stock characteristics that over the long term have presaged outsize performance had perverse results: Stocks with bargain prices, superior earnings growth, and even strong price momentum, underperformed. On the other hand, stocks with below-market volatility, rich dividend yields and high profitability were being rewarded far more than usual.
The situation did not totally reverse in the October rally, but return factors behaved more normally, as hopes grewat least for a timefor political and policy solutions to the European sovereign-debt crisis.
Similarly, some of the worst-performing sectors in the earlier part of the yearalmost all of them economically sensitive, such as industrials and materialswere the winners in October. Meanwhile, Septembers safe havens, such as utilities and consumer staples, lagged.
Perhaps, you might say, the prized and shunned factors (and sectors) simply switched places, and if so, investors should concentrate on stocks with the factors that have traditionally done best.
Not so fast. October may have produced a red-letter rally, but volatility remains disconcerting, with markets rising and falling in response to various US and European political developments. How many investors are confident that the market has found its footing again? Not many, as the market volatility in November shows. Count us in the ranks of the less than confident.
In our view, it is wiser to diversify your holdings to gain exposure to stocks with a wide range of characteristics, including some that are paying off meagerly now. This is a time to embrace diversificationby sector, geography, style and stock characteristics. Its a time to tread carefully when it comes to taking risk.
When conditions and sentiment improve, stock return factors are likely to behave more normally. But perhaps the biggest lesson of the past few years is that even in more normal times, investors should diversify their overall portfolios broadly across risk and return factors.
