Engagement Brief: Allocation Adjustment Strategy for NorthBridge Invest
Company context
NorthBridge Invest (NBI) is a US-based digital wealth platform (robo-advisor + hybrid advice) serving 2.4 million funded accounts and $38B AUM. NBI’s core product is a set of five model portfolios (Conservative, Balanced, Growth, Aggressive, and ESG Growth) implemented primarily through low-cost ETFs. Roughly 82% of AUM is in the robo-only product; the remaining 18% is in a premium tier that includes access to CFPs.
NBI grew rapidly from 2020–2022, but growth has slowed. In 2025, NBI added only $2.1B net new AUM (vs. $6.4B in 2023) and saw a rise in outflows among older clients. The CEO believes the platform’s allocations—designed during a low-rate era—may no longer reflect the best risk-adjusted opportunity set, especially given higher cash yields and changing correlations.
NBI’s investment committee meets quarterly. You are the Strategy Lead supporting the CIO and Head of Product. Your task is to recommend whether NBI should adjust its model allocations, and if so, how to do it in a way that improves client outcomes while minimizing churn, regulatory risk, and operational disruption.
Strategic situation: why now
Three events are forcing a decision:
- Macro regime shift: Markets are pricing 150 bps of Fed cuts over the next 12 months. The CIO expects duration to perform, but worries about inflation re-acceleration.
- Equity concentration and “Mag-7” exposure: NBI’s US equity ETF sleeve has drifted toward mega-cap tech; the Balanced portfolio’s look-through exposure to the top 10 US stocks is estimated at ~28% of US equity sleeve.
- Competitive pressure: Two competitors are marketing “next-gen” portfolios:
- EverOak (fast-growing fintech) is pushing risk-parity-inspired allocations and private credit intervals for high-balance clients.
- HarborWealth (incumbent broker) is bundling tax-loss harvesting + direct indexing and claims improved after-tax returns.
NBI’s board wants a clear recommendation within 6 weeks so that any changes can be implemented before the next peak funding season (January IRA contributions).
Current model portfolios (simplified)
NBI uses strategic weights with quarterly rebalancing bands. Current weights are:
| Sleeve | Conservative | Balanced | Growth | Aggressive | ESG Growth |
|---|
| US Equity (broad market) | 20% | 35% | 45% | 55% | 40% |
| Intl Equity (developed + EM) | 10% | 15% | 20% | 25% | 25% |
| Investment-Grade Bonds (intermediate) | 55% | 40% | 25% | 10% | 20% |
| TIPS | 5% | 5% | 5% | 5% | 5% |
| REITs | 5% | 3% | 3% | 3% | 5% |
| Cash | 5% | 2% | 2% | 2% | 5% |
Fees: NBI charges 25 bps on robo AUM (no trading commissions). Weighted average ETF expense ratio is 7 bps.
Client base and behavior
- Client segments by AUM:
- Mass market (<$25k): 55% of accounts, 18% of AUM
- Core ($25k–$250k): 40% of accounts, 52% of AUM
- Affluent (>$250k): 5% of accounts, 30% of AUM
- Annualized churn (accounts with net outflows >50% of balance):
- Conservative: 9.5%
- Balanced: 7.0%
- Growth: 6.2%
- Aggressive: 7.8%
- Top reasons cited in exit surveys (multiple select):
- “Moved to cash / money market”: 34%
- “Wanted more downside protection”: 22%
- “Fees too high”: 18%
- “Wanted more customization / tax optimization”: 16%
Market and competitor data (assume these are credible)
- US robo-advisor AUM (2025): $1.2T, expected 10% CAGR through 2029.
- Typical robo fee range: 15–35 bps.
- EverOak claims its new allocation reduced 2022 drawdown by 3.5 percentage points vs. a traditional 60/40 benchmark.
- HarborWealth claims direct indexing improves after-tax returns by 0.7–1.2%/yr for taxable accounts over $100k.
Constraints
- Regulatory/Compliance: Any change must be defensible under fiduciary standards. Marketing claims must be supportable; cannot imply guaranteed outcomes.
- Operational: Trading must be staged to avoid market impact and client confusion. NBI can tolerate at most 15% of AUM traded per week.
- Product/Engineering: Only 8 engineering weeks are available this quarter for portfolio logic changes (rebalancing bands, drift monitoring, and disclosures).
- Client communications: Must provide 30 days’ notice for material changes, plus updated risk disclosures.
Your deliverables (what you must answer)
- Decision framing: What factors should NBI consider when recommending an allocation adjustment (investment, client, competitive, operational, and regulatory)? Provide a structured approach.
- Quantitative sizing: Estimate the potential business impact (AUM retention and revenue) of (a) doing nothing vs. (b) adjusting allocations. Use reasonable assumptions and show your math.
- Competitive analysis: Evaluate how allocation changes could strengthen NBI’s positioning versus EverOak and HarborWealth. Where can NBI credibly differentiate?
- Recommendation: Propose a specific allocation adjustment (e.g., changes to bonds duration, cash, factor tilts, alternatives, or tax-aware features). Explain trade-offs and who benefits/loses.
- Go-to-market and rollout: Outline a phased plan for implementation and client communication, including success metrics and guardrails.
You may ask clarifying questions, but assume you cannot run new backtests during the interview; you must reason from the information above and general finance/strategy principles.
