Cracking the Code of Long-Term Stock Returns: A Two-Step Screening Method to Find True Value Creators

Generating nearly one hundred billion dollars in free cash flow annually while simultaneously executing a hundred-billion-dollar stock buyback program, Apple Inc. uses financial data to reveal the standard configuration of an outstanding enterprise.

The most common confusion in investing is: why can some companies' stock prices traverse cycles and continuously reach new highs, while other seemingly decent companies remain stagnated for long periods?

Apple's return on equity has long remained above 150%, and during the same period it announced a $100 billion stock buyback plan. This is not merely an accumulation of financial data, but a window into understanding enterprise value creation.

01 Core Principle: Why Do These Two Metrics Determine Long-Term Returns?

To understand the essence of investment returns, one must return to the most fundamental financial logic. A simple formula can reveal this logic: Total Shareholder Return ≈ Return on Equity + Dividend Yield + Valuation Change.

Among these, return on equity is the内生 engine through which enterprises create value for shareholders, measuring how much profit a company generates per dollar of shareholder investment. A company that consistently maintains a high ROE typically possesses strong competitive advantages and pricing power.

Meanwhile, net inflow rate reflects how friendly the market ecosystem is to shareholders. Its calculation formula is: Net Inflow Rate = (Total Dividends + Total Buybacks - Total Financing) / Total Market Capitalization. A positive value means the market is delivering value to shareholders; a negative value indicates the market is continuously draining value from shareholders' pockets.

These two metrics together form a complete analytical framework: ROE determines an enterprise's capacity to create value, while the net inflow rate determines how much of that value can actually flow to shareholders.

Part of the reason for the U.S. stock market's long-term strength lies precisely here. As of August 2025, the annual stock buyback volume of U.S. listed companies has exceeded $1 trillion, with Apple, Alphabet, and other tech giants contributing a significant portion. This cycle of "create earnings — return to shareholders — enhance per-share value" forms a structural支撑.

02 Step One: How to Correctly Analyze and Interpret ROE

The first step in finding outstanding enterprises is to analyze their profitability, but one must look beyond surface-level numbers to grasp the essence.

Collect Basic Data:

Find the company's ROE data over the past 5-10 years, observing its stability and trends
Calculate the industry average ROE to determine the company's relative position within the industry
Decompose ROE's constituent parts (Net Profit Margin × Asset Turnover × Equity Multiplier)

In-Depth Analysis Using Apple as an Example: According to the latest financial report data, Apple's FY2025 ROE reached 151.91%, and this figure approached a peak of nearly 197% in FY2022. Such sustained high levels are exceedingly rare among large enterprises.

However, looking solely at the ROE figure is insufficient. One must追问: how is such a high ROE achieved? Is it through high leverage? By analyzing Apple's financial statements, you will find that its success primarily derives from extremely high net profit margins and asset turnover efficiency, rather than financial leverage.

Advanced Verification Tools:

ROIC Analysis: Apple's average return on invested capital over the trailing 12 months is 43.44%. This metric strips out the influence of financial leverage, confirming that its high ROE originates from genuine operational advantages.
Free Cash Flow Verification: In FY2025, Apple generated $98.767 billion in free cash flow, with a free cash flow yield of approximately 2.47%. This is a more "real" profitability metric than accounting profit.
Earnings Quality Assessment: Monitor the ratio of operating cash flow to net profit — consistently above 1 is a healthy signal; simultaneously analyze whether profit growth is primarily driven by core business operations.

The core of this methodology is: Do not be misled by a single high ROE figure; instead, deeply analyze its composition, sustainability, and cash conversion capability.

03 Step Two: Evaluating Capital Flow at the Market and Enterprise Levels

After identifying a profitable enterprise, the next step is to determine whether it is willing to share its success with shareholders.

Market-Level Net Inflow Rate Assessment:

Collect overall market data: annual total dividends, total buybacks, IPO and refinancing totals
Calculate overall market net inflow rate = (Total Dividends + Total Buybacks - Total Financing) / Total Market Capitalization
Observe the long-term trends and cyclical variations of this metric

Enterprise-Level Shareholder Return Analysis:

Examine the company's capital allocation policy: Does it have explicit dividend and buyback policies? How does management decide on the use of cash?
Analyze actual return history: Does the company consistently increase dividends? Does it increase buybacks when stock prices are depressed? Apple's $100 billion buyback plan announced in 2025 is a clear value signal.
Assess return sustainability: Compare the company's free cash flow with the scale of shareholder returns, ensuring that returns do not compromise the company's financial health or growth potential.
Be alert to dilutive behavior: Frequent secondary offerings, low-priced equity incentives, and similar actions erode existing shareholders' interests.

Key Judgment Point: Excellent management demonstrates "shareholder-friendly" characteristics in capital allocation: returning surplus cash to shareholders when growth opportunities are limited; prioritizing buybacks over dividends when stock prices fall below intrinsic value.

04 Practical Case: A Complete Analytical Framework for Apple

Let us apply this methodology to an actual analysis of Apple:

ROE Analysis:

Level: 151.91% (FY2025), at an absolute高位
Trend: Continuously rising from 87.87% in 2020 to a peak in 2022, then maintaining high levels
Driving factors: Gross margin rising from 38.23% to 46.91%, net profit margin growing from 20.91% to 26.92%
Verification metrics: ROIC at 43.44%, free cash flow at $98.767 billion

Shareholder Return Analysis:

Policy: Explicit combined dividend-plus-buyback return strategy
Scale: $100 billion buyback plan announced in 2025
History: Multiple years of large-scale buybacks, significantly reducing outstanding shares
Sustainability: Abundant free cash flow, robust financial structure

Comprehensive Assessment Conclusion: Apple exhibits a perfect combination of "high profit creation capability" and "high willingness to return value to shareholders," which explains why it has become a favorite of long-term investors.

05 Application Adjustments Under Different Market Environments

This analytical framework requires flexible adjustments in different market environments:

Mature Markets (e.g., U.S. Equities):

Key focus: Effectiveness of buyback activities (whether conducted when price is below value)
Opportunity identification: Seek enterprises where ROIC consistently exceeds WACC (Weighted Average Cost of Capital) and that actively return value to shareholders
Risk caution: Avoid enterprises that overly rely on financial leverage to maintain high ROE

Growth Markets:

Metric adjustment: For enterprises in rapid expansion phases, appropriately relax net inflow rate requirements
Key focus: Capital allocation efficiency — whether new investments can translate into higher future ROE
Balancing art: Finding a balance point between growth investment and shareholder returns

Market Comparison Analysis:

Analytical Dimension	Mature Market Characteristics	Growth Market Characteristics	Investment Strategy Focus
ROE Level	Relatively stable, pronounced industry differentiation	Higher volatility, growth enterprises may be lower	Mature markets focus on stability, growth markets focus on trends
Net Inflow Rate	Typically positive, buybacks are a significant component	May be negative, financing activities are frequent	Mature markets focus on return scale, growth markets focus on financing efficiency
Key Verification Metrics	ROIC, FCF, Dividend Coverage Ratio	Revenue growth, investment return cycle, market share	Mature markets emphasize quality verification, growth markets emphasize growth verification
Primary Risks	Growth stagnation, excessive financial engineering	Financing dilution, investment failure, cash flow断裂	Mature markets guard against value traps, growth markets guard against growth narrative collapse

06 Construct Your Investment Checklist

Based on the above analysis, I have summarized a practical investment checklist for you:

Step One: Initial Screening

Average ROE over the past 5 years > 15% (adjustable by industry)
ROE trend stable or upward, not violently fluctuating
Enterprise is in or building competitive advantages within its industry

Step Two: In-Depth Analysis

High ROE driven by high profit margins or high asset turnover, not excessive leverage
ROIC consistently exceeds WACC, indicating genuine economic profit creation
Abundant free cash flow, with a healthy ratio to net profit (typically > 70%)
Operating cash flow consistently growing with less volatility than net profit

Step Three: Shareholder Return Assessment

Has an explicit and sustainable shareholder return policy
Has consistently implemented dividends or buybacks over the past 3-5 years
Shareholder return scale matches free cash flow, without excessive debt
Management has a track record of increasing buybacks when stock prices are undervalued

Step Four: Market Environment Adaptation

Understand the net inflow rate characteristics of the overall market in which the enterprise operates
Adjust metric weighting according to the enterprise's lifecycle stage
Assess the rationality and necessity of the enterprise's financing behavior

Step Five: Final Decision

Composite score exceeds comparable companies in the same industry
Current valuation provides a reasonable margin of safety
Management possesses a shareholder-friendly culture and a good capital allocation track record

The most dangerous idea in investing is searching for a "silver bullet metric," while the most reliable method is establishing a systematic analytical framework. ROE and net inflow rate are not two isolated numbers, but rather a window into透视 the essence of enterprise value creation and distribution.

When you search for investment targets among thousands of companies, this two-step analytical method can quickly filter out those enterprises that do not create value or do not respect shareholders.

The fairest aspect of capital markets is that they ultimately reward only those enterprises that genuinely create value and share it with shareholders. Finding and accompanying such enterprises is the most powerful compounding tool that ordinary investors can master.
