The sharp upturn in stock prices since the start of the current calendar year has taken most investment professionals by surprise.  Indeed, consensus opinion contained in the lengthy annual investment tomes released by brokerage houses just weeks ago, predicted that the major stock market indices would remain volatile and tread water into the summer, as concerns over the state of the global economy alongside the seemingly never-ending crisis in the euro-zone, was expected to keep investors’ natural bullish appetite in check.

Further, gains of the magnitude enjoyed during the opening weeks of 2012 were not envisaged until the second half of the year, by which time it was contended, that the large concerns weighing on market sentiment would have diminished, as if by magic.

Needless to say, the notion that directional changes in stock prices can be anticipated beforehand with such precision is decidedly naïve, yet Wall Street strategists continue to engage in this fruitless pursuit year after year regardless.  However, just as the upturn in equity prices has left bewildered strategists with egg on their faces, the stock market’s behaviour has presented technical analysts – the students of historical price patterns – with the opportunity to step forward and salivate over a supposedly bullish market development – a ‘Golden Cross.

A ‘Golden Cross’ is said to occur when the stock market’s 50-day moving average of closing prices rises above its 200-day moving average and, is considered by technical analysts to be a portent of future price strength.  Absent a major market setback, the S&P 500 should register the alleged bullish signal to much fanfare by the time this column is published but, is the ‘Golden Cross’ really worthy for inclusion as an input that helps guide tactical positioning?

There have been 43 ‘Golden Crosses’ since January 1928, and the signal has been followed by twelve-month returns of more than nine per cent on average or two percentage points above the long-term mean.  The signal has delivered positive twelve-month returns on 32 occasions or almost three-quarters of the time and, has been followed by above-average returns over the subsequent year on 23 occasions or more than half the time.

The historical record appears to suggest that the so-called ‘Golden Cross’ does deliver respectable returns on an annual horizon, though the incidence of above-average returns is not much better than a coin-toss, while the frequency of loss – at more than one-in-four – is not significantly below long-term experience.

More importantly, the strength of the signal appears to depend on whether it is associated with a recession-induced decline or not.  There have been 15 signals through the past eight decades that were registered as equity prices were recovering from a recession-induced bear market and, the average twelve-month return subsequently recorded has been an impressive 19 per cent or twelve percentage points above the long-term mean.

Further, a recession-recovery signal has been followed by above-average twelve-month returns on thirteen occasions or more than 85 per cent of the time and, has resulted in negative returns just once way back in 1938.  Thus, the historical record confirms that the ‘buy’ signal heralded by the ‘Golden Cross’ is worth heeding when it is associated with a recession-induced stock market decline but, can the same be said for the remaining 28 non-recession signals?

The answer would appear to be no.  Of the 28 non-recession ‘Golden Crosses,’ only ten or little more than one-third were followed by above-average twelve-month returns and, a further ten signals saw negative returns over the subsequent year – an incidence of twelve-month loss that is higher than the historical stock market record.

The erratic performance of the non-recession signals is such that the returns subsequently delivered lag the stock market’s historical mean return over any short-term period worthy of note, including three-, six-, nine-, and twelve-month horizons.  On an annualised basis, the signal’s performance lagged returns that could have been generated by chance over the respective short horizons by three to four percentage points.  In a nutshell, ‘Golden Crosses’ that are not associated with an economic downturn do not work and, have no place in the toolbox of seasoned investors.

Unfortunately, human beings are hard-wired to detect patterns and associations – even when none exist – in an effort to find order amid the endless chaos.  This evolutionary quirk allows investment strategists and technical analysts to issue precise short-term forecasts that satisfy our hunger for order and placate our natural optimism.

The bullish signal emitted by the non-recessionary ‘Golden Cross’ is a classic example of such nonsense and, investors who act on such misguided advice should know that in evolutionary terms, they are behaving little differently than a moth who chases a flame.

At what point do we stop wondering what the crystal ball will show next?  Lately, every time I turn on the TV, the newscaster is announcing a new prediction for our economic future.  Sometimes two channels are simultaneously reporting completely different forecasts.  At this rate, how can one put faith in any of these hypotheses?  Will we eventually tire of these predictions (which are really nothing more than educated guesses) or will we just give up and roll with the punches?

Our favorite Irish economist Charlie Fell explores our "Prediction Addiction" in his latest blogpost.  Read the full article here.

 

Prediction Addiction

Human beings are hard-wired to detect patterns and identify causal relationships amidst the constant stream of new information.  This behaviour can be traced to our ancestral past on the African savannah many millennia ago, where the ability to shape expectations from small samples of data, enabled our hunter-gatherer ancestors to successfully forage for edible fruits and seeds, stalk prey, avoid predators, find shelter, and seek mates. 

Scott Huettel, a neuroeconomist at Duke University, explains that, “The brain forms expectations about patterns because events in nature often do follow regular patterns:  When lightning flashes, thunder follows.  By rapidly identifying these regularities, the brain … can expect a reward even before it is delivered.

The ability to anticipate outcomes from regular patterns undoubtedly helped our ancestors to flourish but, Huettel warns that, “in our modern world, many events don’t follow the natural physical laws that our brains evolved to interpret.” The human brain is designed to conserve scarce neural resources, and so much so, that it requires only a single confirmation to anticipate a recurring pattern.  Huettel notes that as a result, “The patterns our modern brains identify are often illusory…

Pattern recognition and subsequent tactical buy or sell decisions are part and parcel of active investment management.  Investors however, often place too much emphasis on the recent past when forming expectations about the future – top-down analysts make tactical calls based on recent economic data, while technical analysts divine the future on historical patterns in stock prices.

Investors’ ‘prediction addiction,’ as the behaviour has been called by the financial columnist, Jason Zweig, is particularly relevant today.  Economists are busy shaving their economic growth forecasts for both this calendar year and next, following a string of disappointing data that fell well short of expectations.  Meanwhile, technical analysts are arguing for a reduction in equity allocations, given price action in the major stock market averages that confirms a change in the underlying trend.

Recession fears are afoot and investors are in need of guidance that will preserve capital and/or yield profits amid the uncertainty.  Indeed, anticipating turning points in the business cycle and, adjusting asset allocation accordingly, is central to successful top-down investing.

Unfortunately, economists have a patchy forecasting record at best, having failed to anticipate every one of the last five recessions.  Indeed, the monthly publication, Blue Chip Economic Indicators, noted in July 1990 that, “the year-ago consensus forecast of a soft landing in 1990 remains intact” – the economic expansion peaked that very month!

More than a decade later in March 2001, fewer than five per cent of economists anticipated that there would be a recession that year, even though a downturn was set to begin just days later.  More recently during the spring of 2008, the calls for a soft landing were almost deafening, despite the fact that the deepest recession since the 1930s was already underway.

Perhaps the study of historical price patterns performs better.  After all, stock price data is not reported with a lag and, unlike economic data, is not subject to revisions that continue several quarters after the fact.  As William Hamilton, the fourth editor of the Wall Street Journal wrote in his 1922 classic, ‘The Stock Market Barometer’ – “The market represents everything everybody knows, hopes, believes, anticipates, with all that knowledge sifted down to ... the bloodless verdict of the market place.”

The study of historical price patterns suggests that a further decline in the major market averages may lie in wait.  The 18 per cent fall in stock prices from their recent peak late-April, resulted in a bearish ‘Death Cross’ signal on August 12, as the stock market’s 50-day moving average of closing prices dropped below its 200-day moving average.

The ‘Death Cross’ is considered by technical analysts to be a portent of future weakness, but is the signal’s presumed ability to anticipate turning points and enhance investment performance supported by the historical record?  To find out, the ‘Death Cross’ and its converse, the ‘Golden Cross’, are employed as tactical sell and buy signals respectively, for a simple long/short strategy and, the investment results – excluding dividends – are compared with those generated from a straightforward buy-and-hold strategy.

The historical record shows that before the most recent ‘Death Cross,’ there had been 63 tactical signals since the summer of 1949 – 32 buy and 31 sell signals – which, gives weight to the late Paul Samuelson’s criticism in 1966, that ‘The stock market has predicted nine out of the last five recessions.

The buy and sell signals resulted in 33 winning trades and 30 losing trades, which is not much better than a coin toss.  More importantly, the price return generated by the long/short strategy saw an initial $10,000 investment compound to $537,000 over the period, as against $775,000 for the buy-and-hold strategy.

The historical evidence suggests that the ‘Death Cross’ adds no value to the investment process.  However, a more complete examination of its credentials reveals that it subtracts from investment performance during secular bull markets, which are characterised by powerful up-trends with only the briefest of interruptions; it adds to performance during secular bear markets, which are characterised by a protracted sideways pattern that is punctuated by violent downward price swings.

The bearish indicator provided ample warning to investors of impending danger, close to a market top in both the autumn of 2000 and the winter of 2007.  Has the ‘Death Cross’ sounded an early warning bell once again?  Time will tell.
