Is Technology Speeding Up Market Cycles?

“Short-termism is the tendency to make decisions that appear beneficial in the short term at the expense of decisions that have a higher payoff in the long term.” – Michael Mauboussin

Tim Ferriss fielded some listener questions in his latest podcast one of them caught my attention: What is a trend you see developing that a lot of people are missing?

Ferriss gave an interesting answer for investors to consider. He thinks the speed with which we disseminate information is having an impact on market cycles. Specifically, that there’s an acceleration in the ups and downs of market cycles from the flow of information and its instantaneous dissemination through channels such as social media and other forms of online communication.

Think about the oil decline that’s seen the price of one of the world’s most important commodities fall from almost $110 a barrel in June to under $60 just six months later. No one really knows why the price has fallen so swiftly. Yet it’s entirely possible that people are extrapolating things they think will happen in the energy space in the future based on supply and demand forecasts and continued innovation. Combine that with quick hit decisions, leveraged speculators and, right or wrong, we’ve seen an enormous crash in an extremely compressed time frame with one of the most useful natural resources on earth.

William Bernstein, the brilliant author and investor, discussed the length of time we should see between boom and bust cycles based on market history in his book The Four Pillars of Investing. The book was published in 2002, just as markets were starting to mend from the aftermath of the tech bubble:

The Great Internet Bubble will not be the last of its kind, but if history is any guide, we should not see anything approaching it until the next generation of investors takes leave of its senses, sometime around the year 2030. If the current generation gets caught out again, we should be very disappointed, as no previous generation has been so dense as to have been fooled twice. But then again, the Boomers have shown a singular talent for gullibility, and there is still plenty of time.

Little did he know that there would be another massive crash just five years later after the real estate bubble imploded. Globalization means it’s not just a U.S. phenomenon anymore either. It was a global debt bubble that popped in 2007 and many of the countries around the world are still trying to deal with it.

Everyone wants to blame the Fed for everything in the markets these days because of their low interest rate policies, but rates were at similarly low levels throughout the 1930s and 1940s during the painstakingly slow recovery following the Great Depression. On a price basis it took 25 years to surpass the 1929 stock market peak as risk aversion stayed with that generation for a very long time (although on real return basis, with dividends reinvested, it took only four and a half years because of the severe deflation experienced at the time).

Following the Great Recession, the S&P 500 surpassed the previous 2007 all-time high only 6 years later in nominal price terms. Plus, while the peak of the market was in late-2007, over 65% of the losses from the crash occurred in just six months, from mid-September of 2008 (after Lehman Brothers failed) to early-March of 2009. It seems everything is happening at a quicker pace these days.

Earlier this year Vanguard interviewed their head of fixed income just before he retired to ask him how bond investing has changed over his three-plus decades of investing (emphasis mine):

One big difference between when I arrived at Vanguard and today is the speed of the markets. In 1981, when a news event occurred, you could sit and contemplate it. If something happened overseas, it might not affect U.S. markets, and if it did, it took a day or so. Now geopolitics is so much more important. Everything is instantaneous. We have to make snap decisions all the time without waiting.

Problems result, according to Ferriss, when the information becomes contaminated. There’s no way that everyone’s instant reactions are going to be correct. In fact, more often than not, it’s our gut instinct that leads us down the path of irrational decisions. Technology now allows irrational exuberance, misinformation and fear to spread around the world at a frightening pace.

This is why the glut of information is both a blessing and a curse. It’s very easy to access, which levels the playing field for people all around the world. And social media allows for instantaneous feedback on just about everything. The problem is when people make snap decisions without waiting or contemplating the ramifications. The world is now geared towards short-termism. Many default to an act-first, think-later mindset. When the implications of our decisions aren’t accompanied by enough time and deep thought, unintended consequences will occur with more frequency.

Many textbook relationships and historical rules of thumb have been virtually useless over the past 5-6 years following the crash. I think the speed of market cycles has a lot to do with this and it’s one of the reasons so many people have had trouble with this market environment.

I agree with Ferriss and think this is something that only becomes more pervasive in the future.

    It is obvious that information is reflected in prices much more quickly, but I’m not convinced the bull/bear cycle has accelerated. A quick peak at a log historical chart shows that our recent peak/troughs are actually further apart than they have been historically, albeit much greater in magnitude.

    Economic cycles may have accelerated due to faster and more aggressive policy response. Technology has likely increased volatility in the markets, which seems to be closer to what you are trying to convey.

    I do not think the fear/euphoria/bubble market cycle will accelerate unless our memories get shorter.

      I also think this will be more pervasive in certain segments/sectors of the market. We’ve seen this in the past couple of years with biotech, social media, energy, etc. I think those smaller areas of the market will be impacted more so than the markets overall.

    Nice post. I’m curious as to where you got your figures for the 4 1/2 year recovery from the 1929 crash, in real terms with dividends reinvested. According to this source,

    the S&P did not recover it’s September 1929 peak until November 1936 which it held for only 4 months until March 1937, then crashed again and did not recover to the September 1929 peak until January 1945, over 15 years later.

    […] The moves in the markets listed above have already outpaced the averages in this table, but the declines were much worse than the majority of historical S&P 500 bear markets. I think it’s also possible that market moves are speeding up these days because of technology. […]
