Portfolio Compass

Where should we grow, maintain, improve profitability or reduce?

The Decision Question

Portfolio steering requires more than knowing which segments are profitable today. Underwriters also need to know whether those segments remain attractive enough to support, and whether the current price adequately reflects the risk being taken.

A segment can be attractive but underpriced. Another can be adequately priced but offer little strategic value. A third may combine strong economics with good growth prospects.

The decision is therefore two-dimensional:

Do we want more of this business?

Are we being adequately paid for it?

Bringing those questions together creates a clearer basis for underwriting action.

Default practice

Portfolio steering is commonly approached through some form of portfolio matrix, heat map or scorecard.

Traditional strategy frameworks plot market attractiveness against business strength, with actions ranging from invest and grow through to maintain, harvest or exit. Insurance versions of the same idea tend to use measures such as profitability, expected return, risk, outlook, underwriting appetite and growth potential.

Insurers may then classify segments into actions such as:

• Grow

• Maintain

• Improve profitability

• Reduce or exit

Supporting underwriting views often add more detailed measures such as rate adequacy, renewal performance, expected loss ratio, capital usage, market conditions or distribution strength.

The weakness is that these measures are often presented separately. The profitability view may sit on one page, appetite on another, and growth expectations somewhere else again. The underwriting action then has to be inferred from several pieces of analysis.

That makes it harder to see the portfolio as a set of competing choices.

Suggested upgrade

Bring rate adequacy and strategic attractiveness together in a Portfolio Compass.

The vertical axis shows whether current pricing is adequate relative to the required level. The horizontal axis shows how attractive the segment is strategically.

Strategic attractiveness can be built from a transparent score combining factors such as market opportunity, strategic fit, competitive position, distribution strength, capital efficiency, diversification and available capacity.  The factors can be scored and weighted to create a consistent measure across segments, while still making management judgement explicit.

Together, the two measures point towards four broad underwriting directions:

• Grow — attractive business with adequate economics.

• Maintain / Selective — adequately priced business where there is limited reason to actively expand.

• Improve profitability — strategically attractive business where the economics need work.

• Reduce / Exit — weak economics combined with limited strategic attraction.

The centre of the compass is deliberately left as a Watch zone. Small movements around the decision boundaries should not automatically trigger a strong underwriting response. The Watch zone recognises that weak signals around the centre may justify monitoring rather than immediate action. The further a segment moves from the centre, the stronger the action signal becomes.

Bubble size shows the current premium or exposure, adding materiality to the decision. A small hollow marker shows the prior-year position, with a dotted trail to the current position.

This adds an important dimension to the view. Two segments can sit in the same action area but tell very different stories. One may be improving after pricing or underwriting intervention, while another is continuing to deteriorate.

The Portfolio Compass therefore shows four things together:

·         Where the segment sits.

·         How material it is.

·         What broad action it suggests.

·         Whether it is moving in the intended direction.

The compass sets the portfolio direction. The underlying analysis still determines the intervention - whether that means rate, terms, deductibles, limits, risk selection, capacity or distribution action.

Trade-offs and risks

The Portfolio Compass simplifies a more complicated underwriting decision.

The first risk is the choice of measures. Rate adequacy depends on the pricing basis, expected claims assumptions and the definition of an adequate return. Strategic attractiveness is more judgemental and may combine factors such as market opportunity, strategic fit, distribution strength, capital efficiency and diversification.

The action boundaries can also create false precision. A segment close to the Watch zone may not be meaningfully different from one sitting just inside an action area. The Watch zone helps make that uncertainty visible, but the Compass should still support judgement rather than determine the action automatically.

There may also be important differences hidden within a segment. A weak-looking portfolio class may contain profitable niches, strong brokers or attractive individual risks. Likewise, an attractive segment may become less attractive once concentration, catastrophe exposure or capital consumption is considered.

Underwriting actions also have consequences. Repricing can affect retention and portfolio mix. Tightening terms can change customer behaviour. Reducing business can weaken broker relationships or reduce diversification. Growth can consume capital or create concentration faster than expected.

The Compass works best as a way to identify where management attention is required. The underlying analysis then determines the precise intervention.

Decision Boundary

Use this when...	Don't use this when...
You want to track whether portfolio actions are moving segments in the intended direction over time	The underlying adequacy or attractiveness measures are too uncertain to support meaningful comparisons
You need to compare portfolio segments and decide where to grow, maintain, improve or reduce	You need to make an individual risk or policy-level underwriting decision
You want to combine economic adequacy with strategic attractiveness in one view	You need detailed diagnosis of why a segment is underperforming
You want to prioritise where underwriting action is most needed	You need to set the exact rate, deductible, limit or wording change
You want to show materiality using premium, exposure or capital	Segment definitions are too broad and hide materially different risks
You need a portfolio-level discussion between actuarial, underwriting and management teams	You need a standalone view of profitability, retention, capital or model performance
