Newspapers, complained the British prime minister Stanley Baldwin in 1931, enjoy “power without responsibility – the prerogative of the harlot throughout the ages”.

The influence of the press is greatly diminished since Baldwin’s day. Yet there remains an uneasy feeling that newspapers, and newspaper columnists in particular, get away with far too much, writing whatever ill-informed nonsense pops into their heads without ever being held to account.

So with 2018 drawing to a close, and Abacus now more than 100 columns old, this seems like a good time to look back over the last year or so to assess how my analyses have panned out, and how my forecasts have withstood the harsh test of time.

Reviewing 2018’s calls, the first thing that stands out is a forecasting fail of epic proportions. In the last week of January, with Hong Kong’s benchmark Hang Seng stock market index up 10 per cent since the beginning of the year, I predicted that “the rally has further to run”.

Why the Hong Kong bull market is set to run and run

The reasoning was sound enough – as far as it went. I argued that the fears of international investors that China would suffer a crippling financial crisis were grossly exaggerated. As a result, they were underinvested in the Hong Kong market. When they woke up, Hong Kong-listed stocks would play catch-up.

As it turned out, that column pretty much coincided with the Hong Kong market’s all time high. In the following months, far from rallying further, it would give back all its gains and more, to sit 14 per cent down on the year last Thursday.

So how did I get things so catastrophically wrong? First, I didn’t foresee the short squeeze executed just a few days later on US volatility traders, which knocked 10 per cent off the value of US equities in a matter of days and severely dented sentiment towards stock markets around the world.

Second, I failed to appreciate how badly the rally in the US dollar triggered by that risk-off move would injure non-US markets. Coupled with a tight supply-demand balance for oil, which drove the price of crude up 38 per cent over the next nine months, the US currency’s strength saw liquidity tighten across much of the world, and stock markets, including Hong Kong’s, sell off heavily.

It was a bad mistake. But it didn’t stand for long. Within two weeks, I had revised my call, warning that conditions were changing, and that financial markets were heading for a year of heightened volatility.

This was a theme I revisited. In the weeks that followed, I warned that a rising US dollar, rising US interest rates, and more expensive oil would hammer Asia, with Indonesia and India especially vulnerable. Between late January and early October, the Indonesian rupiah fell 13 per cent against the US dollar, the Indian rupee 15 per cent.

US$400 billion? Er, calm down. The MSCI is no biggie for Chinese stock markets

I also argued that, contrary to the stories being spun by bankers and brokers, inclusion in MSCI indexes would not boost mainland Chinese stocks. It didn’t; they are down 24 per cent on the year. And I suggested that high quality Chinese bonds might offer a hiding place. Despite the fall in the yuan, a basket of Chinese bonds traded in Hong Kong has returned 1.2 per cent this year. That might not sound much, but it is better than almost every asset class out there apart from US dollar cash.

Abacus would be a very dull column if it only concerned itself with financial markets. Over the last year or so it has explored many other themes – and happily most of its forecasts have proved more accurate than January’s disastrous call on the Hong Kong stock market.

For example, Abacus sounded the alarm early over deepening economic tensions between the US and China. Back in March it warned that “in the coming months, the US is likely to slap tariffs, fines and other penalties on specific Chinese companies and sectors” in what threatened to become “a new economic and technological cold war directed at China”.

US-China trade war: not about trade, not about Trump. Here’s what it is about

Repeatedly over the following months, Abacus stressed that the conflict was about far more than trade. In April the column argued that “the US objective is not to win trade concessions … but to force a change in China’s whole economic and industrial policy approach”.

And in early November, it argued that a deal between Donald Trump and Xi Jinping in Buenos Aires at the beginning of December to avert tariffs “will do little, if anything, to bring peace in the rapidly escalating economic cold war between the United States and China”.

This reality was driven home within days of the Trump-Xi trade deal by the arrest in Canada of a senior executive of the Chinese technology giant Huawei at the request of the US authorities.

Don’t ask why US acted against China’s Huawei. Ask: why now?

Looking back even further, Abacus has made some other happy calls. For example, in early December 2017 with cryptocurrency fever raging and prices up 1,000 per or more over the year, the column explained exactly why “the bubble that last week propelled the price of bitcoins to a record high is clearly unsustainable. At some point it must burst”. Just over 12 months later, bitcoin is down 80 per cent.

Time and again over the last two years, the column has tackled misconceptions about China’s economy, arguing that Chinese banks were not about to collapse, that it was not about to see mass capital flight, and that its debt-laden financial system was not heading for a Lehman-style meltdown.

Equally, it also argued that Xi Jinping was no economic reformer, and that Beijing was not about to prop up sagging growth rates with a 2009-style stimulus programme; all forecasts that have subsequently proved correct.

But Abacus’s most consistent and most prescient call has been that China’s “Belt and Road” international infrastructure development programme was heading for trouble.

Why China’s ‘One Belt, One Road’ plan is doomed to fail

As far back as August 2016, the very first Abacus argued that China was proposing excessively costly debt-funded projects in countries that had little capacity to absorb them economically. China, it warned, “will end up building white elephants, wasting money, and encouraging corruption on a scale never before seen”.

As a result, the column’s headline proclaimed that “China’s One Belt, One Road plan is doomed to fail”.

At the time, the column attracted much excoriating criticism. Nearly two and a half years later, its arguments have become so accepted that last week the South China Morning Post’s editorial page announced that “the Belt and Road has failed”.

But I’m still burning with embarrassment and shame about that bad Hong Kong stock market call.
