What it means
After a sharp fall, buyers often step in because prices look cheap, and sellers who panicked have already left. Prices then move up, sometimes quickly.
That move is the rebound. Not every rebound means the bad news is over.
A short-lived bounce within a longer decline is sometimes called a relief rally or a dead cat bounce. A genuine recovery usually has support from better earnings, improving economic data or a clear fix for whatever caused the drop.
The arithmetic of recovery is often misunderstood. A fall of 20% needs a rise of 25% to get back to the starting point, because the gain is applied to a smaller base.
The deeper the fall, the harder the climb: a 50% loss needs a 100% gain. Analysts measure rebounds in two ways.
One is the percentage gain from the low point, and the other is how much of the earlier fall has been recovered, known as retracement. Both help to judge strength, and traders often watch for retracements of particular fractions as signs of where a rebound might stall.
For a business, the idea applies beyond share prices. A company's sales, a currency or a local property market can all rebound.
Finance teams plan for the possibility by stress testing forecasts for both a slow and a fast recovery, because assuming the wrong shape can distort budgets. Timing is the hard part for any investor.
Waiting for proof of a rebound means paying a higher price, while buying too early risks catching a falling market. Many investors spread purchases over several months to avoid betting everything on one date.
In practice
Real-world examples.
Example
A retailer's shares fall 30% after a weak profit warning, and then recover 12% when management announces cost savings. Analysts debate whether this is a true rebound or a temporary bounce. The next results show a better margin, which supports the recovery. Over the following months, the share price climbs a further 20% from its new level.
Example
A country's economy shrinks 6% during a downturn and then grows 4% the next year. The rebound is real but incomplete, because output is still about 2.2% below the starting point. Businesses revise their plans to expect a slow return to the earlier level.
Example
A property fund sees values fall 15% and then stabilise. An investor with $500,000 to invest waits for signs of a rebound, such as rising transaction numbers. She invests in stages instead of all at once to reduce the risk of timing it wrongly. For example, she puts in $100,000 every quarter for five quarters.
Formula
Calculation
Rebound % = (Recovery price - Low price) / Low price x 100; Retracement % = (Recovery price - Low price) / (High price - Low price) x 100
Suppose a share falls from a high of $100 to a low of $80, a drop of 20%. It then recovers to $88. The rebound from the low is (88 - 80) / 80 = 10%, while the retracement of the earlier fall is (88 - 80) / (100 - 80) = 8 / 20 = 40%. To get fully back to $100, the share must still rise 100 - 88 = $12, and from the low it needs a gain of 20 / 80 = 25%.Case study
Seen in the real world.
Bluewave Travel Group is an illustrative, fictional tour operator whose revenue falls from $60,000,000 to $24,000,000 during a regional crisis. The finance director builds a recovery plan with two scenarios.
In the fast scenario, bookings rebound by 60% in the first year, taking revenue to $38,400,000. In the slow scenario, they rebound by 25%, taking revenue to $30,000,000, which means the company would still be 50% below its former level.
She sets the budget on the slow case, keeps the staff costs flexible and secures a credit line of $5,000,000. In this illustrative case, the bookings follow the fast path, and the company is able to add capacity quickly because it had planned for either outcome. Revenue reaches $38,400,000 in the first year, which is 38,400,000 / 60,000,000 = 64% of the old level.
Watch out
Common mistakes.
- Believing a rebound of the same percentage as the fall restores the original value, when a 20% fall needs a 25% rise.
- Treating every bounce as the end of a decline when it may be a short relief rally.
- Buying all at once at the first sign of a rebound instead of building a position gradually.
Questions
People also ask.
How long does a rebound last?
There is no fixed length, as some last days and some last years, depending on the cause of the fall and the economy. Looking at earnings, spending data and credit conditions helps judge whether it is likely to last.
What is a dead cat bounce?
It is a brief rise in a falling market that is followed by further declines.
Is a rebound the same as a recovery?
Often they are used interchangeably, although recovery usually implies a return to the previous level while a rebound can be any upward move. A market can rebound many times during a long decline without ever fully recovering.
