Anchoring Bias can quietly distort long-only equity decisions and reduce compounding. At Carvina Capital Pte. Ltd., we outline how to identify and counter the anchoring effect within disciplined processes.
Key takeaways
- Anchors from entry price, past highs or opinions bias entries, exits and sizing.
- Checklists, base rates and scenario ranges reduce anchor reliance, improving decision quality.
- Risk budgets, liquidity buffers and pre-committed sell rules limit losses from anchored positions.
Market Context Now
As at May 2021, developed equity markets trade close to prior highs, while cross-section dispersion remains material. This backdrop rewards disciplined selection and patient capital, yet it increases
the risk of decisions anchored to salient price levels.
Flows into passive vehicles have continued through the prior 12 months to April 2021, reinforcing index anchors for many participants. For long-only managers, the challenge is to remain valuation-led and process-consistent as narratives and anchors shift.
Volatility has normalised relative to the extremes of 2020, yet episodic drawdowns still occur. Resilience comes from pre-defined rules that prevent anchors, such as recent peaks, from dictating action.
Our Research Lens
We frame each investment as a fresh decision, independent of entry price or recent highs. We start with base rates, peer-group economics and scenario analyses that map value drivers, then we test against alternative hypotheses. Checklists enforce coverage of unit economics, balance-sheet resilience, capital allocation, governance and catalysts. We document pre-mortems, explicit sell triggers and time-boxed reviews to avoid drifting with the anchoring effect.
Risk is assessed as a probability-weighted range of outcomes, not a point estimate. Position sizes reflect expected downside at the portfolio level, liquidity conditions and correlation paths across the cycle.
Portfolio Construction
Position sizing follows expected-loss constraints at position and portfolio levels. Initial weights are smaller when uncertainty is high or when anchors are likely, such as after sharp rallies. Risk budgeting allocates drawdown capacity to independent theses. We scale exposure as thesis quality improves, and we reduce or exit when facts diverge from our decision record, irrespective of purchase price.
Liquidity is managed by maintaining a buffer sized to the prior 12 months of observed trading conditions. We avoid crowding in names where exit liquidity could compress exactly when anchors tempt investors to hold losers.
ESG Integration in Practice
ESG analysis is embedded in our checklists and valuation ranges. We avoid anchoring to static ratings, and instead track forward indicators such as governance quality, workforce safety and credible transition plans. These inputs affect thesis quality, required returns and sizing.
Signals We Are Watching
We monitor market breadth and dispersion to identify when narrative anchors dominate price action. We track estimate-revision breadth and the distribution of beat-miss asymmetry to detect inflection in fundamentals. We review checklist-adherence statistics and post-mortem error rates to audit our process. Liquidity indicators, including order-book depth and turnover persistence, inform sizing and exit discipline.
Strategic Considerations
We expect episodic volatility to persist through 2021, with frequent references to recent highs shaping investor behaviour. Our emphasis remains on valuation ranges, balance-sheet strength and quality of execution.
Portfolio actions will continue to follow pre-committed rules. We will trim or exit when facts breach our thesis, even if the price sits below our entry, and we will add when base rates and forward returns justify it.
For professional readers evaluating similar frameworks, we suggest codifying anchor-neutral decision points, testing them on 2000–2020 history, then enforcing them with governance. This discipline has supported compounding for Carvina Capital and is central to our long-only practice, including our ongoing evaluation of potential retail accessibility.
