The Only Thing Driving the Stock Market

The Only Thing Driving the Stock Market

It turns out that investing is really very simple — in a way.

Howard Wang of Convoy Investments explains that investment prices are driven by the amount of money and assets.

Asset price = quantity of money/supply of assets.

If there are $100 in the world and only one investment, then that investment is worth $100. If you double the amount of money, you get 100% gains in the asset price.

Ignoring the details for a moment, does this hold true? Pretty much, according to his chart:

Let’s gradually make the example more complex to get closer and closer to reality.

Imagine there are two investments. In this scenario, the growth in investment prices can be uneven as money flows from one to the other. But the total growth from a doubling of the money supply still gets you 100% gains if you hold an evenly diversified portfolio.

Of course, the definition of what the money supply is becomes very complex. The government and its economic henchmen at the central bank only have control over the monetary base, and not how much credit is created by the banking system or the velocity of money.

But the point that Wang is making is clear: The money supply drives investment prices.

Is that good news or bad?

Well, the US money supply is expected to shrink in the coming years as the central bank winds down its quantitative easing (QE) efforts. Other central banks will follow in time. The net effect is that the monetary base of major economies is falling as of this year.

Does that mean the stock market will perform badly?

Perhaps. Don’t forget that credit and the velocity of money come into the equation.

And if the stock market is part of the modern central bank’s mandate, then it’s easy for the central banks to reverse their policies at any moment.

Any crash shouldn’t get out of hand.

There is one exception, though. The European Central Bank is bound by a bundle of rules on its QE. Some of these are limits to the level of QE it can implement. That means, if the world consistently turns to monetary policy as a rescue mechanism, Europe could be the first to hit a wall.

The Eurozone’s monetary system is downright bizarre thanks to the separation of nations but shared monetary policy and currency. The financial plumbing designed to make the euro work is leading to vast imbalances that nobody understood a few years ago, let alone when it was conceived.

What are the investment implications? Well, first, I’d steer clear of any European assets. Although perhaps investing in northern Europe could make sense.

I don’t know whether he’s advocating this style of investing or not, but Wang points out that a diversified set of investments leaves you in an intriguing position.

Because the flows of funds between investments don’t affect you — for every loss, there’s a gain — you’re left with exposure to the money supply. It’s like betting on the tide instead of the regatta.

The result is that your basket of assets follows money supply growth. Like this:

Ultimately, knowing all this doesn’t leave you with an obvious solution.

Predicting the money supply is difficult. Even if you believe central bankers’ forecasts about their behaviour, banks and the velocity of money are the dominant considerations.

But if Wang is right, it does tell you what to watch.

Unfortunately, he’s missing something.

Money can flow into and out of investment assets altogether

There’s another factor which Wang hasn’t taken into account. It’s called the life-cycle hypothesis.

The idea is that people buy investments during middle age. And then sell them in retirement.

If you can track how many people are in the buying-age cohort and how many are in the selling-age cohort over time, you can map the supply and demand for investments too.

That might make it easier to forecast investment prices into the future.

Until next time.
