Market Dynamics: Understanding Why There’s No Panic

As we approach the end of August and a holiday weekend, another discussion surrounding President Biden’s attempts to dismiss Lisa Cook seems unnecessary—there have been plenty of those already.

Instead, let’s delve into a philosophical question: Why isn’t the market reacting wildly? This topic was brought up by Paul Krugman recently. While I see where he’s coming from, my take on it is a bit different.

First, let’s recall Benjamin Graham’s well-known assertion that, In the short term, the market is a voting machine, but in the long term, it’s a weighing machine. To break this down further:

The market operates as a probability machine.

Sure, people “vote” with their dollars, but saying that doesn’t quite help us understand what’s going on right now.

I’ve come to a more useful framework that considers three main factors:

1. The future remains largely uncertain (“No one knows anything”)
2. Investors express their expectations through capital allocation
3. Market consensus is formed through these capital flows.

Let’s elaborate a bit:

When I claim No one knows anything, I mean that none of us can predict how current issues like inflation or corporate earnings will pan out. We can analyze trends and offer educated guesses, but, ultimately, the outcomes are unknown.

Still, through capital investment, individual perspectives start to take shape. We create forecasts, assess risks and rewards, and allocate funds based on those considerations. What Graham described as “votes” are actually these financial commitments. Together, they form a collective market consensus. Sometimes it’s accurate—leading to soaring highs—and sometimes it misses entirely, resulting in downturns. Each situation reflects the collective probability of what might possibly occur.

Take a look at this excerpt from James Surowiecki’s book Crowd Wisdom. On January 28, 1986, he recounts how investors reacted to the Space Shuttle Challenger disaster.

“Within minutes, investors started selling off stocks related to the four main contractors involved with the Challenger launch, particularly Rockwell International, which built the shuttle and its engines.”

By day’s end, the stocks of the first three companies were down only about 3%, while Morton Thiokol saw a drop of 12%. Many interpreted this market reaction as a reflection of crowd wisdom, associating it with destructive design flaws tied to Morton Thiokol.

I see it differently.

The market couldn’t know the full ramifications. Instead, investors made probabilistic evaluations regarding how negligence might impact the profitability and stock prices of these firms.

Rockwell, valued at $800 million, was intertwined with various industries including aerospace and automotive. Lockheed, at $2.5 billion, was a major defense player, while Martin Marietta, valued at $300 million, dabbled in both aerospace and chemicals. Interestingly, Morton Thiokol, the smaller player worth $1.7 billion, had significant exposure to the aerospace sector, with over 18% of its sales linked to NASA contracts. In contrast, Rockwell and Martin Marietta saw less than 12% of their sales tied to these contracts. This discrepancy meant that if negligence was found within any of these companies, Morton Thiokol would be hit hardest profit-wise.

The market evaluates probabilities, often independent of who is at fault.

So, why isn’t the market going haywire? Right now, the prevailing sentiment is one of optimism about high profits and potential economic strength, spurred by forthcoming interest rate cuts. Yes, there’s plenty of political noise, but perhaps there’s an underlying belief that it will resolve favorably.

Of course, one could argue that market sentiment is a cocktail of wishful thinking and rational assessment. In hindsight, what looks like market madness often feels more like a logical stance based on then-current information. Indeed, markets offer a spectrum of potential outcomes reflected in their pricing.

The variability of results can lead to divergent and sometimes contradictory interpretations of risk. There have been times when that disconnect was evident, but we also have to acknowledge that there are moments when the market remains unsure.

It’s a tricky balance to gauge probabilities, especially when considering specific opportunities tied to people, politics, or policies. Understanding the Federal Reserve’s influence is a separate beast altogether, and figuring out its implications for future pricing is even trickier. Ultimately, we just don’t know yet.

If you’re curious about the issue of Fed independence, I recommend checking out John Hilsenrath’s insights from August 8th. He’s been an authority in this space for quite some time.

“The president is in line to appoint three supportive voices to the Fed’s seven-member board next year, including Governors Waller and Bowman. This could give the President a significant influence over the Fed’s decisions.”

It’s a clear illustration of the current landscape, and it leaves us pondering the market’s future adjustments to these evolving circumstances.

In the meantime, I watch as Mr. Market weighs various potential outcomes…
