The 4-Layer Framework for Evaluating Any Stock
Most stock picks fail one of four filters. A disciplined framework — Regime, Quality, Timing, Risk — separates repeatable winners from lucky ones. Here is how the four layers stack.
Most retail investors evaluate stocks along a single dimension: 'is the chart looking good?' or 'is the P/E cheap?'. Institutional investors think in layers. A stock that passes the technical filter can still be a terrible investment if the underlying business is weak or the market regime is hostile. This is the four-layer framework we use inside EthicoIQ.
Layer 1 — Market Regime (25% weight)
Before you look at any individual stock, ask what environment the market is in. A great stock in a hostile regime often loses money. A mediocre stock in a friendly regime often makes money. The dominant regime should influence which factors you weight most heavily.
- Index trend vs 200-day moving average
- Market breadth (percentage of stocks above their 50-DMA)
- Sector rotation and relative strength
- Volatility regime (VIX level and trend)
- Liquidity conditions (rate environment, credit spreads)
Rule of thumb: if the broad index is below its 200-DMA and breadth is deteriorating, cut new-position sizing in half regardless of how bullish the individual stock's technicals look.
Layer 2 — Company Quality (30% weight)
The single most important filter, and the reason it carries the highest weight. Great businesses recover from bad quarters. Weak businesses do not.
- Revenue growth and revenue acceleration
- EPS growth and EPS acceleration
- Return on equity / capital
- Debt-to-equity and interest coverage
- Free cash flow generation
- Institutional ownership trajectory
- Relative strength vs sector and index
You do not need every metric to be perfect. Look for three or four strong pillars and no red flags on the rest.
Layer 3 — Technical Timing (25% weight)
Even a great business at a great regime can be a poor buy today. Technical timing determines the when, not the whether.
- RSI (14) — is momentum stretched?
- MACD histogram — is the trend accelerating or fading?
- ADX — is there any trend at all?
- Supertrend / EMA alignment — is the structure supporting the direction?
- Volume confirmation on the recent move
- Breakout above prior resistance, or bounce off tested support
Technical timing works dramatically better after the first two filters have passed. Applied first, it produces noise.
Layer 4 — Risk & Reward (20% weight)
The most under-appreciated layer. A great business at the right time can still be a bad trade if the risk/reward is wrong. Many profitable strategies win only 45–55% of trades but make money because winners are much larger than losers.
- ATR-based stop-loss placement (not arbitrary percentages)
- Minimum 2.5:1 reward-to-risk at the intended entry
- Position sizing rules that cap single-name exposure
- Correlation between the new position and existing holdings
- Portfolio-level exposure limits (never more than X% in one sector)
- Trailing stop discipline to lock in gains
Putting It Together: The Opportunity Score
Combine the four layers with weights and you get a single 0–100 opportunity score:
Opportunity Score = 0.25 × Regime + 0.30 × Quality + 0.25 × Timing + 0.20 × Risk
Alongside the score, publish separate metrics: Confidence (data completeness), Risk (downside), Entry Quality, Exit Quality, Position Size, Portfolio Impact. Users benefit from seeing not just how attractive a setup is, but how reliable the signal is.
Adaptive Weights by Regime
The same framework does not weight the same way in every environment. In a bull market, Trend and Momentum carry more; in a bear market, Risk and Fundamentals dominate; in a sideways market, mean reversion and support/resistance matter more. Adaptive weighting outperforms static weighting because it adjusts to changing conditions.
Frequently Asked Questions
Why is Company Quality weighted highest?
Because it is the layer that determines long-run outcomes. Regime, timing and risk decisions can be corrected within days. A poor-quality business is a decision you compound for years.
Does this framework work for day trading?
The layers apply; the weights shift. Day traders should weight Technical Timing (35–40%) and Risk & Reward (25–30%) heavily and give Company Quality less emphasis. Regime still matters — do not day-trade breakouts in a deteriorating tape.
