Rebound
Overview
Rebound (反騰, rebound) is a financial and economic term referring to the phenomenon in which a falling asset price or economic indicator temporarily turns back into an upward trend. It is used in all markets, including stocks, bonds, foreign exchange, and commodities, and in macroeconomics it can also mean the phase in which the economy revives after a recession. A rebound is conceptually distinguished from a reversal (反轉, reversal), in which the trend itself changes, and it is judged by duration, trading volume, and whether fundamental changes accompany it.
Key Details
Definition and Etymology
It uses the Chinese characters 反 (to turn back) and 騰 (to rise). In other words, it means turning back a downward flow and rising. In a narrow sense, it refers to a short-term rise during a correction phase; in a broad sense, it includes the overall flow in which economic, sentiment, and real indicators hit a bottom and improve. In English, bounce, rally, rebound, recovery, etc. are distinguished according to context.
Types of Rebound
1. Technical Rebound: A short-term rise that appears when buying flows in from an oversold condition or when short covering of short positions overlaps. It often occurs only from price adjustment without substantive changes such as earnings or policy.
2. Trend Rebound: A rise accompanied by fundamental factors such as earnings improvement, interest rate cuts, or a policy shift, with a relatively high probability of leading to a reversal.
3. Dead Cat Bounce: A trap-like rebound that briefly rises after a sharp drop and then continues the downward trend again. It is known as an expression that originated on Wall Street in 1985.
4. Economic Rebound: Refers to the phase in the business cycle that moves from recession to recovery. It takes the form of real indicators such as manufacturing PMI, exports, and facility investment bottoming out and rising.
Classification by Shape
- V-shaped rebound: A shape that bottoms out and recovers sharply right away. It appears when policy responses are quick or fear was excessive.
- U-shaped rebound: After moving sideways for a certain period at the bottom, it recovers gradually.
- W-shaped rebound: It rises after forming two bottoms and consolidating the floor. Also called a double-bottom pattern.
- L-shaped: A case of stagnating at a low level for a long time without a rebound; Japan's Lost Decade is cited as a representative example.
Difference Between Rebound and Reversal
A rebound is a temporary retracement within an existing downward trend, whereas a reversal means the direction of the trend itself changes. In practice, judgments are made comprehensively based on ① whether both highs and lows are rising (shift to an uptrend), ② whether trading volume is increasing, ③ whether major moving averages (60-day and 120-day lines) are recovered, and ④ whether there are fundamental changes such as earnings or policy.
Rebound in Technical Analysis
Support line confirmation, an oversold zone with RSI below 30, a MACD golden cross, a return after breaking below the lower Bollinger Band, and excessive divergence are used as rebound signals. However, technical indicators are lagging, so reliability increases when they are interpreted together with trading volume.
Rebound in Macroeconomics
An economic rebound appears as a process in which leading indicators (new manufacturing orders, PMI, consumer sentiment index), coincident indicators (industrial production, retail sales), and lagging indicators (employment, unemployment rate) improve sequentially. Interest rate cuts, expanded fiscal spending, export recovery, and a turning inventory cycle are the main drivers.
Indicators Used to Identify a Rebound
- Trading volume and trading value
- Whether the credit spread (difference between corporate bond and government bond yields) narrows
- Initial unemployment claims
- Volatility indices such as VIX
- A shift to net buying by foreigners and institutions
- Commodity prices and the freight rate index (BDI)
Latest Trends (2024-2025)
In early August 2024, the Bank of Japan's interest rate hike and weak U.S. employment data coincided, causing global stock markets to plunge, and Korea's KOSPI also fell by more than 8% in a day, triggering a circuit breaker. Afterward, as concerns over unwinding the yen carry trade subsided, major indices showed a V-shaped rebound that recovered most of their losses within a few weeks.
In the second half of 2024, the AI and semiconductor sectors led the rebound, and in 2025, expectations for major central banks entering an interest rate cut cycle, changes in U.S. tariff policy, and China's economic stimulus measures acted as key variables causing repeated rebounds and corrections. In the Korean market, the corporate value-up program and dividend expansion policies were mentioned as materials for a rebound in undervalued stocks.
In addition, as the share of retail investors increased, the tendency for buying flows to rush in quickly during declines strengthened, and accordingly, a pattern in which rebounds become faster but less sustainable is often observed. As of 2025, the interest rate path, whether inflation rebounds again, geopolitical risks, and the AI investment cycle are cited as the four major variables that determine the sustainability of a rebound.
Investment Utilization and Cautions
During a rebound phase, gradual buying, rebalancing, and setting stop-loss criteria in advance are recommended. In particular, chasing buys during a dead cat bounce can lead to large losses, so one should not judge based only on short-term fluctuations without confirming trading volume and fundamentals. Since a rebound is often a concept confirmed in hindsight, an approach centered on risk management rather than forecasting is required.
