When Forward P/E Mislabels Risky Cyclicals
May 26, 2026 at 03:05 UTC
Equity markets currently rely heavily on forward P/E multiples even where earnings are temporarily elevated. This practice is common in cyclicals such as semiconductors, energy producers, and transport names, where profitability can swing sharply with macro conditions, industry supply, and capital spending cycles.
History shows that when forward P/E is anchored to earnings boosted by intra-ecosystem spending, macro-sensitive demand, or temporary supply constraints, apparent cheapness often proves fragile. Cisco (CSCO) during the 2000 networking boom, Micron (MU) in the 2017-2018 memory upcycle, and shale producers like Pioneer Natural Resources (PXD) ahead of the 2014-2016 oil downturn each traded on seemingly low forward multiples before earnings reset and valuations compressed.
The same interaction between cyclical earnings and valuation remains relevant for current leaders. NVIDIA (NVDA) depends heavily on concentrated AI infrastructure capex, while A.P. Moller-Maersk (MAERSK-B.CO) is tied to container freight cycles and prior supply-chain tightness. In all such cases, the key issue is not the headline multiple, but how much of the earnings base reflects conditions that are unlikely to persist at mid-cycle levels.
Terminology
- Forward P/E: Price divided by forecast next-period earnings, used to value equities.
- Cyclicals: Companies whose earnings move strongly with economic and industry cycles.
