Growth Factor
A-share growth factors: revenue and earnings growth
Growth factors measure changes in revenue, earnings and cash flow. High growth can come from durable improvement, but also from a low base, acquisitions or a one-off item.
Typical direction
Higher sustainable revenue, earnings and cash-flow growth is commonly ranked higher.
Data
Financial statements and matched historical periods
Refresh
Year-on-year, TTM year-on-year or multi-year CAGR
Research hypothesis
Write the hypothesis before reading the backtest
Sustainable operating improvement may contain information when the market has not fully priced it; low-base effects, acquisitions and expensive valuations can reverse the signal.
A factor is a testable research hypothesis, not an investment recommendation or return promise.
Factor health card
Pre-backtest checks for this factor
Research purpose
Test whether operating improvement survives quality and valuation checks.
Refresh and rebalance
Refresh after filings; do not use period-end figures before disclosure.
Data timing
Choose one growth convention: quarterly YoY, TTM YoY or CAGR.
Neutralisation
Compare within sector and flag low-base or acquisition cases.
Overlapping exposures
Often paired with quality and investment factors.
Check before use
Identify mergers, loss-to-profit transitions and one-off gains.
Definitions
Core measures
Revenue growth
Current revenue ÷ prior-year comparable revenue − 1M&A and price effects can distort the change.
Earnings growth
Current attributable income ÷ prior-year comparable income − 1Treat negative or near-zero bases separately.
Revenue CAGR
(End revenue ÷ start revenue)^(1/years) − 1Smooths one period but reduces new-listing coverage.
Growth acceleration
Current growth rate − prior growth rateMore sensitive to noise and base effects.
Research protocol
Keep the same research conventions across factors
Data availability
Financial, dividend and share data become available on actual disclosure or implementation dates, not report-period end dates.
Universe and exclusions
Document index membership, listing age, ST, suspensions, delistings and missing-data rules.
Processing and neutralisation
Version winsorisation, standardisation, sector/size neutralisation and missing-value rules.
Tradability
Include price limits, suspensions, participation, fees, slippage and market impact.
Out-of-sample review
Report IC, grouped returns, exposures, turnover and rolling out-of-sample evidence together.
Build and validate
What to test
- 1Separate revenue, earnings and cash-flow growth.
- 2Report valuation and asset-growth exposures.
- 3Test multiple post-disclosure holding windows.
Common pitfalls
- ×Ranking loss-to-profit changes mechanically.
- ×Mixing quarterly and cumulative growth rates.
- ×Treating high growth as a signal without valuation context.
A-share implementation
A-share checks that belong in the backtest
- Use the actual disclosure or implementation date; do not make a field available at the report-period end date.
- State the universe, listing-age, ST, suspension, delisting and missing-data rules before running the backtest.
- Model price limits, suspensions, fees, slippage and participation limits instead of assuming every close can be traded.
- Major consolidation changes should be flagged before comparing year-on-year growth.
Research prompt
A reviewable starting prompt
“In CSI 500 non-financial stocks, construct sector-neutral TTM revenue and earnings-growth scores with cash-flow quality filters. Use filing dates, exclude abnormal merger cases and report valuation, turnover and rolling out-of-sample results.”
FAQ
Does high growth mean the stock is attractive?
No. Growth can be transient or already priced. Check cash flow, base effects, valuation and later-period results.
Why use sector neutralisation?
Growth rates and accounting patterns differ by sector. Neutralisation reduces the chance of only selecting one sector cycle.
