What cyclicality actually means in practice, and why it matters for evaluating industrial businesses
When listening to a discussion on the industrials sector, the term "cyclicality" is almost guaranteed to appear, and for a good reason. Industrials are one of the most highly cyclical sectors, containing sub-sectors like automotive, airlines, and construction which move drastically with the current state of the economy. Broadly speaking, the idea appears quite intuitive. Earnings grow when businesses are spending and contract when that spending slows. However, the concept goes much deeper. Different segments run on different cycle lengths and cycle drivers that further define how each operates in various economic environments. Throughout this piece we will break down what fuels these cycles, the different phases of the cycle, and how different businesses operate within them.
The Drivers of the Industrial Cycle
Cycles are deeply rooted in demand and supply, which result in capital allocation decisions and market competition strategies that further shape how they play out. When businesses are confident future demand will rise, more capital gets directed toward new CapEx and increased capacity. Industrial companies see spikes in orders for new machinery, construction projects, and materials to support expected demand. Demand will often outweigh supply initially, increasing prices and further supporting the earnings spike. As increased returns within a specific industry become more apparent, new competitors arise to capitalize on the opportunity. New supply enters the market and eventually reaches a level above the current demand. For example, during Covid many manufacturers repurposed their operations to produce medical equipment like masks, medical gloves, and hand sanitizers, then quickly refocused on other markets once need for these goods slowed. As orders slow down, suppliers are forced to downsize operations back to more normal levels.
Other economic factors like interest rates and macro events also play a crucial role in the timing and length of the business cycle. Interest rates directly affect how willing a business is to take on new expansion. Unexpected shifts in rates can expedite spending or delay it even when underlying demand hasn't changed. Macro events add another layer of unpredictability within business cycles. Unforeseen policy change or geopolitical shocks can derail expansion even when it was previously well justified. We can see something similar with the impact on oil prices since the start of the Iran conflict. Take airlines, who expected to see a year of strong travel and growth, that are now reallocating capital to manage fuel pricing, along with lower passenger volumes from international safety fears and the partial government shutdown causing TSA impairments. These issues often compound through supply chains causing more pain to the businesses involved than the overall economy will likely feel.
Phases of the Cycle
The cycle is defined by four main phases: expansion, peak, contraction, and trough.
Expansion – This phase arises through a meaningful recovery following a cyclical downturn. Suppliers are seeing notable increases in order volume as companies begin resuming investment, and supplier backlog begins to grow. Short-cycle industries are generally the first to feel the effects with growing revenues against a cost basis that was likely cut during the downturn to preserve margins. These are businesses with quick inventory turnover and wide customer access, such as parts distributors, maintenance suppliers, and industrial consumables. As confidence builds, larger commitments to growth become more apparent, such as increased hiring and long-term investment from longer-cycle industries. Stock performance potential is often high at this stage given the sentiment is improving. Expectations for meaningful earnings growth aren't overly priced-in, which is what creates the opportunity.
Peak – The peak comes when activity is at its highest, but the rate of activity growth is slowing. At this stage, competition has grown and supply now better meets current demand levels at a lower price. This simultaneously puts pressure on input costs. Suppliers of finished goods are all competing for the same input materials, just to turn around and undercut each other, compressing margins. Backlogs, while often still material, are locked into these lower margins. Over-investment risk becomes a bigger concern with significant amounts of capital allocated to cover demand that may not be sustainable much longer.
Contraction – This phase signals the downturn of the cycle. The demand spike begins to diminish, and suppliers lose the pricing power they once had. Excess supply from the peak becomes a painful and costly situation with minimal demand to offload it. Capacity that was added to support the increased demand is now being underutilized, and companies begin to turn their focus from protecting growth to protecting cash. Discretionary spending is often first in line to get cut as companies delay non-essential maintenance and repairs over taking on new costs while revenues are declining.
Trough – The trough is the weakest condition of the cycle, but it is also the beginning of a recovery into the next cycle. Production slows dramatically as suppliers work through excess inventory built up during the peak. Eventually, inventories deplete, and new demand begins to accumulate with time and a price reset. The repairs and maintenance that were put off during the contraction have reached their limit, forcing spending before confidence even fully returns. Suppliers must ramp back up production to meet the growing demand, paving the way for the next expansion.
Closing Takeaway
While this cycle appears clean when presented in this way, it's important to note that there is no catch-all structure when analyzing cyclical companies. Short-cycle businesses will turn faster on both ends and can be more susceptible to external shocks making their cycles more volatile. Long-cycle businesses will turn slower each way and are less likely to be impacted by minor bumps in the economy due to lengthy contracts and extensive backlogs. However, this can pose other challenges like increased difficulty of investment timing given the almost perfect environment needed to enter a true expansion and peak period. What investors can be more confident in is the consistency of cycle patterns across different timelines. A producer of wind turbines will likely experience the same cycle as a fastener manufacturer, just on very different timelines. This is because no matter the product, cyclical businesses within industrials are highly reliant on the broader economic picture and future outlook.
For an investor, understanding the cycle doesn't tell you what to buy or when to buy it, but it can help you break down what supporting events must occur for your investment thesis to play out as intended. Take a cyclical market like freight. Instead of just comparing the big players to see who is best positioned, an investor that understands the cycle can focus on supporting data like whether or not capacity is falling, or if tender rejection rates are on the rise. Being able to analyze both individual companies and the broader environment they operate in is key in building an informed investment thesis.
