Why do some trends last for decades while others fade away?

Some products appear on the market with a lot of buzz and excitement, only to disappear almost as quickly. Some others, meanwhile, didn’t gain much traction at the start, but have today become nearly indispensable.

Consider mobile phones, for instance. What entered the market as expensive, bulky devices have now become a part of our daily lives, shaping how we communicate, shop, and even work.

The difference between what fades and what endures is at the heart of understanding long-term change. For investors, recognising this distinction can provide context for separating short-term market noise from the structural forces—sometimes called megatrends—that can shape industries over time.

What gives a trend the ability to stay?

Trends that endure for years, sometimes decades, tend to have certain qualities:

• Widespread adoption: Trends gain strength when they move from small groups to the mainstream. Example: Smartphones, once niche and expensive, are now central to daily life worldwide.
• Practical value: They solve real problems or make life easier in a lasting way.
  Example: Digital payments reduce friction in transactions and have transformed how people shop and transfer money.
• Adaptability: They evolve with technology, culture, or customer needs. Example: The internet expanded from desktop browsing to mobile, cloud, and now AI-enabled services.
• Economic support: They fit within existing business models or create new profitable ones. Example: Solar and wind power have become cost-competitive with fossil fuels, driving mass adoption.
• Regulatory push: Policies, subsidies, or legal requirements can reinforce certain directions. Example: Global climate agreements and government incentives accelerating renewable energy adoption.
• Underlying structural drivers: Some trends endure because they are anchored in powerful long-term forces, such as demographics or climate change.
  Example: Ageing populations driving persistent demand for healthcare and retirement planning.

These elements can give a trend the potential to turn into a structural shift. However, outcomes are not guaranteed – not every significant change turns out to be a megatrend.

Indicators of structural change

So, how can you spot the early signs that a trend might evolve into a sustainable business shift rather than fade away? A few indicators include:

• Integration into daily habits: When people start using a product or service almost without noticing, it signals lasting relevance.
  Example: The way mobile payments have become routine in many countries.
• Infrastructure investment: Governments or businesses begin building systems, platforms, or facilities that support it.
  Example: The rollout of EV charging networks to support electric mobility.
• Shifts in consumer expectations: Customers begin to view certain features or services as standard. Example: Fast delivery in e-commerce is now seen as a given, not a premium option.
• Global or demographic tailwinds: Broader forces such as ageing populations, urbanisation, climate change, or digital literacy drive demand. Example: Growing urban populations fuelling demand for smart cities and transport solutions.

These signs do not guarantee success, but they can provide useful context for spotting investment trends that have the potential to endure beyond short-lived excitement.

Examples of long-lasting trends: EVs, digital wallets, clean energy

• Electric vehicles (EVs)
  EVs have been around for years, but recent changes have accelerated their adoption. Battery costs have reduced, charging networks are expanding, and governments are offering incentives. These factors indicate that EVs are part of a long-lasting market shift, especially as they align with environmental goals.

• Digital wallets
  During its early days, mobile payments felt like a convenience for tech-savvy users. But over time, digital payments have become a part of everyday transactions—at grocery shops, for food deliveries, for public transport, and also for paying utility bills. This level of integration makes them a sustainable business trend, supported by both consumer habits and digital infrastructure.

• Clean energy
  Solar and wind power once faced high costs and great scepticism. Now, technology improvements and regulatory support are making them cheaper and more reliable. With climate change high on the global agenda, clean energy is emerging as a megatrend rather than a passing phase.

These examples highlight that trends with lasting power often connect to bigger social, economic, or environmental changes, which is what we see as the difference between megatrends vs. short-term trends.

Conclusion

When thinking about why trends last, it helps to look beyond the initial excitement. Short-term shifts often thrive on novelty, while longer-lasting ones usually meet deeper needs, adapt to change, and receive support across industries and institutions.

By observing how a trend integrates into daily life, how much structural backing it receives, and how well it aligns with wider societal shifts, investors can understand which changes may prove more resilient over time.
