Some quant work on global cyclicality and equities (Wonkish)

I use three indicators in my work and analysis on the blog to describe the global business cycle; a weighted average of growth in global industrial production and trade, compiled by CPB, the global composite PMI, and a diffusion index of OECD’s leading indicators. Strictly speaking, the CPB data in this context are a coincident indicator, while the PMI and OECD LEIs are short-leading indicators. What’s the difference? At the moment the CPB data, updated through February, provide a guide of what happened at the start of 2024 and perhaps an early read on the Q1 GDP numbers, which have just started to trickle out. By contrast, the PMI and OECD LEIs are supposed to offer an early indication of what will happen in Q2. The distinctive lines between these definitions are fuzzy, so I tend to see these three as separate gauges of where global economic activity—with a weight towards developed markets—is right now.

But how do these indicators relate to the equity market? Let’s try to find out.

In the Pipe, Five-by-Five

I recently said that markets were cruising for a bruising. For now, they’re just cruising, mirroring the path set by Corporal Ferro as she guides her drop ship to a perfect landing on LV-426 in James Cameron’s Aliens.

There is still little stopping risk assets, short vol is paying steady premiums for those picking up dimes in front of the proverbial steamroller, and risk-free instruments still offer 4-to-5% for anyone who feels like temporarily getting off the train. In other words, it’s very pleasant indeed for investors. From the perspective of the macro data, that’s easy to explain. Markets are still being fed information that the (global) economy is doing ok, inflation is falling and while interest rates are set to stay high, they’re also about to come down, by 50-to-100bp. Does this story still check out? Just about.

Cruising for a Bruising

Financial market pundits are a bit like dogs chasing cars; they wouldn’t know what to do if they caught one. And so it is that after trying to figure out whether the economy and markets would achieve a soft landing in the wake of the post-Covid tightening cycle, no one quite knows what to think now that the soft landing appears to have arrived.

Let’s list the key requirements for a soft landing.

The BIS gets it wrong on AI/LLM and feminism & reproduction

The BIS has a Bulletin out on the usefulness of AI and large language models. They’re not terribly impressed.

When posed with a logical puzzle that demands reasoning about the knowledge of others and about counterfactuals, large language models (LLMs) display a distinctive and revealing pattern of failure. 

The LLM performs flawlessly when presented with the original wording of the puzzle available on the internet but performs poorly when incidental details are changed, suggestive of a lack of true understanding of the underlying logic. 

Our findings do not detract from the considerable progress in central bank applications of machine learning to data management, macro analysis and regulation/supervision. They do, however, suggest that caution should be exercised in deploying LLMs in contexts that demand rigorous reasoning in economic analysis.
