Why did the new energy vehicle sector pull back sharply from its 2021 peak?

What happened: Represented by the CSI New Energy Vehicle Index (930997), the sector peaked mainly between late 2021 and early 2022, then underwent a sustained decline from 2022 to 2024, with some indices experiencing maximum drawdowns of approximately 60%–70%. New-energy vehicle sales did not decline over the same period: sales in China rose from 3.521 million in 2021 to 6.887 million in 2022 and 9.495 million in 2023, showing that the share-price decline coincided with industry demand growth.

Conclusion: This drawdown was most likely not caused by the invalidation of demand for new-energy vehicles, but by a repricing of the sector’s profitability, cash flow, and return on capital after high valuations and crowded trading in 2021. Rising raw-material costs, excessive capacity expansion, falling capacity utilization, and price wars among automakers meant that “sales growth” did not translate into “profit growth” at the same pace. Global liquidity tightening further amplified the valuation compression in high-valuation growth stocks.

CONFIDENCE

High

The source material provides evidence on index drawdowns, sales growth, valuations, raw-material prices, excess capacity, price wars, and changes in liquidity, together supporting a fairly comprehensive explanation involving “initial valuation compression, subsequent downward revisions to earnings expectations, and continued deterioration in the competitive landscape.” However, peaks and drivers varied across indices, subsectors, and individual stocks, so the relative contribution of each factor cannot be quantified precisely.

CAUSES

Candidate causes

PrimaryExcessive valuations and crowded trading in 2021 set the stage for the drawdown

In 2021, the market had already priced in years of growth in electrification penetration, industry scale, and leading-company positions, pushing sector valuations to high levels. Thereafter, any shortfall in the delivery of earnings, profit margins, or long-term growth expectations relative to assumptions implied by share prices would lead to valuation normalization.

Evidence

In 2021, the CSI New Energy Vehicle Index gained approximately 49.73% year to date, while the market-capitalization-weighted average price-to-book ratio of some new-energy vehicle concept stocks was approximately 12.1x.
By the end of 2021, market commentary already pointed to excessive gains, crowded trading, and valuations in some cases pricing in earnings from the next one to two years.
The CSI New Energy Vehicle Index’s trailing price-to-earnings ratio was approximately 62x in early November 2021 and remained approximately 58x in early 2022.

PrimaryCapacity expansion, excess capacity, and price wars decoupled sales growth from profit growth

Following concentrated capacity expansion across the supply chain from 2020 to 2022, the industry shifted from a supply shortage to competition for orders, utilization rates, and market share. Automakers and supply-chain companies cut prices to compete for demand. Consumers benefited from lower prices, but revenue per vehicle, gross margins, cash flow, and returns on capital came under pressure. This was a major reason the drawdown persisted after 2022.

Evidence

The IEA reported that global battery manufacturing capacity was approximately 2.2 terawatt-hours in 2023, compared with demand of approximately 750 gigawatt-hours; capacity utilization at Chinese battery cell plants was below 40%.
Tesla made substantial price cuts in China in 2023, prompting other automakers to follow suit; price competition remained widespread in 2024.
The source material notes that price wars lowered average selling prices per vehicle and increased promotional and R&D spending, weighing on companies’ gross margins and free cash flow.

PrimaryRising prices of lithium, nickel, cobalt, and other raw materials, followed by a reversal in the commodity-price cycle

The rapid rise in raw-material prices in 2021–2022 initially squeezed margins for battery, materials, and vehicle manufacturers. Later, as new lithium supply came on stream and lithium prices fell, upstream resource companies faced a reversal in earnings expectations and valuation re-rating. As a result, this factor affected different parts of the industry in different ways.

Evidence

The price of battery-grade lithium carbonate rose by more than 400% in 2021.
CATL’s first-quarter 2022 results were affected by higher upstream raw-material costs; its full-year 2022 gross margin was approximately 20.3%.
After lithium prices fell, lithium-resource stocks such as Ganfeng Lithium continued to decline, reflecting a reversal in market pricing of resource prices and earnings expectations.

SecondaryGlobal liquidity tightening compressed valuation multiples for high-valuation growth stocks

The Federal Reserve began tapering asset purchases in late 2021 and continued raising interest rates in 2022–2023, increasing the discount rate applied to future cash flows and weakening risk appetite and financing conditions. This weighed on new-energy vehicle companies with high valuations that were still expanding capacity or making substantial ongoing investments.

Evidence

The Federal Reserve began tapering asset purchases in November 2021 and accelerated the pace of tapering in December 2021.
It raised rates consecutively from March 2022 through May 2023; by September 2022, the federal funds target range had risen to 3%–3.25%.
The source material explicitly notes that this factor was more an amplifier of valuation compression than a single core explanation for the fundamentals of China’s new-energy vehicle industry.

SecondarySubsidy phase-outs and changing policy expectations created a temporary sentiment shock

The phase-out of subsidies prompted the market to test the underlying demand elasticity for new-energy vehicles as policy support waned, and may have brought forward purchases through a rush to buy before the incentives ended. However, sales continued to grow rapidly after the phase-out, so this factor is better viewed as a catalyst affecting valuations and sentiment.

Evidence

The 2022 subsidy standard for new-energy passenger vehicles was cut by 30% from 2021, and the central government’s purchase subsidy officially ended after December 31, 2022.
New-energy vehicle sales rose from 3.521 million in 2021 to 6.887 million in 2022; the end of subsidies did not cause demand to collapse.

SecondaryPandemic disruptions, chip shortages, and supply-chain disruptions

Chip shortages and pandemic restrictions in Shanghai, Jilin, and other areas caused production shutdowns and cuts, delivery delays, and higher logistics costs. These issues may have triggered quarterly earnings shortfalls and accelerated share-price declines in certain periods, but they are insufficient to explain a sector drawdown lasting several years.

Evidence

The source material shows that the industry was affected by the global pandemic and chip shortages in 2021.
In 2022, pandemic restrictions affected some major automotive-industry regions, causing production shutdowns and cuts as well as delivery delays.
Industry sales still grew rapidly in 2022–2023, indicating that this factor was more of a short-term catalyst.

UncertainTrade barriers in overseas markets and downward revisions to globalization expectations

Exports continued to grow, but trade barriers, requirements for local investment, and changes in overseas incentive policies led the market to lower its long-term expectations that Chinese automakers and battery companies could rapidly capture global markets and turn domestic excess capacity into high profits.

Evidence

China’s new-energy vehicle exports reached 1.203 million in 2023, up approximately 77% year over year, indicating that exports were not a failure.
The source material notes that some overseas markets raised tariffs and compliance and localization requirements, potentially affecting long-term valuations.
This factor mainly affected long-term growth expectations from 2023 onward and has limited explanatory power for the first wave of declines in 2021–2022.

Caveats

The “new-energy vehicle sector” is not represented by a single index. Index constituents, weightings, and peak dates differ, so the maximum drawdown of the CSI New Energy Vehicle Index (930997) should not be applied directly to every subsector and individual stock.
The effects of these factors vary across the value chain: price wars primarily weigh on automakers’ and midstream manufacturers’ profits, while falling lithium prices more directly affect upstream resource stocks. The performance of leading companies also differs markedly from that of unprofitable companies dependent on financing.
The source material supports a multi-factor attribution, but does not provide a rigorous return-attribution model. It is therefore not possible to precisely decompose the respective contributions of valuations, liquidity, raw materials, capacity, and price wars to the decline.
Sales growth does not equal shareholder-return growth. The sector’s decline reflects changes in earnings quality, profit distribution, cash flow, and valuation expectations, not a reversal of the industry’s electrification trend.
