Concentrated Stock Positions: The Hidden Risk for Oil Patch and Tech Employees

If you work for a large energy company, a major tech employer, or any company that compensates employees partly through stock, stock options, or a pension tied to company performance, you may have a significant portion of your overall financial life connected to a single company — often without having made a deliberate decision to "invest" in that company at all.

How Concentration Builds Up Without Noticing

Concentration rarely happens through a single deliberate decision — it accumulates gradually:

• Employee stock purchase plans (ESPPs) — often offered at a discount, making it feel like "free money" to accumulate company shares over time
• Stock options or RSUs (restricted stock units) — common in tech compensation, vesting over several years and accumulating into a substantial position if held rather than sold as they vest
• Defined benefit or defined contribution pensions — while not "stock" in the traditional sense, a pension tied to a single employer\u2019s ongoing health represents a concentrated bet on that employer\u2019s long-term viability
• Personal investment choices — familiarity bias often leads employees to buy additional shares of their employer in their personal accounts, on top of compensation-related holdings

Add these together, and it is common for someone to discover — once everything is actually totalled up — that 30%, 40%, or more of their net worth is connected to a single employer, even though no individual decision felt like "betting big" on that company.

The Triple Exposure Problem

For employees of large Alberta energy companies in particular, concentration often compounds across three dimensions simultaneously:

Exposure	What Happens in a Downturn
Employment income	Industry downturns often bring layoffs, reduced overtime, or hiring freezes
Employer stock / options / pension	Company stock typically declines along with the broader sector during downturns
Personal investment portfolio (if also energy-heavy)	Additional energy-sector holdings decline at the same time

The risk is not that any one of these is necessarily a problem on its own — it is that all three can move in the same direction at the same time, for the same underlying reason. A portfolio that looks "diversified" on paper (multiple stocks, multiple funds) can still be highly concentrated in practice if it shares an underlying dependency on the same industry that also pays your salary.

Why People Hold On to Concentrated Positions

Several factors make concentrated positions persistent, even when an employee intellectually recognizes the risk:

• Tax consequences of selling — if shares have appreciated significantly, selling triggers capital gains tax, which can feel like a cost of "fixing" the problem
• Loyalty and familiarity — you know the company, believe in its prospects, and selling can feel like a vote of non-confidence
• Vesting and trading restrictions — blackout periods around earnings announcements or insider trading policies can limit when shares can be sold
• Inertia — without a deliberate plan, shares simply accumulate and remain held by default

Strategies for Managing Concentration

1. Systematic Diversification Over Time

Rather than selling a large position all at once (which may trigger a large tax bill in a single year and feels like a dramatic decision), a systematic plan to sell a portion each year — spreading the tax impact across multiple years and gradually reducing concentration — is often more practical and emotionally manageable.

2. Use Tax-Advantaged Accounts Strategically

If you hold employer stock or have flexibility in how compensation is structured, directing new contributions to RRSPs and TFSAs (invested in diversified holdings) rather than accumulating more employer stock can prevent concentration from growing further, even while existing concentrated positions are gradually addressed.

3. Coordinate the Investment Portfolio With the Concentration

If a concentrated position cannot be reduced quickly (due to vesting schedules, blackout periods, or tax considerations), the rest of the portfolio can be deliberately constructed to avoid compounding the exposure — for example, underweighting the energy sector in other holdings if a large concentrated position already exists in an energy company.

4. Consider the Full Picture, Not Just "Investments"

A genuinely useful concentration analysis includes everything: investment accounts, employer stock and options, pension value (and how it is structured — is it tied to company stock, or to a broader fund?), and even non-financial factors like how specialized your skills are to one industry (affecting how easily you could find comparable employment elsewhere if needed).

A Practical Exercise

If you suspect you may have concentration risk, a useful exercise is to add up, as a percentage of your total net worth:

• Employer stock held directly (in any account)
• Unvested and vested stock options or RSUs (at current value)
• The portion of your pension tied to your current employer
• Any other investments in the same company or sector

There is no universal "correct" percentage — but if this total represents a large portion of your net worth (commonly, concentration above 10–20% in a single company starts to warrant attention, though the right threshold depends on your overall situation), it is worth a deliberate conversation about whether that level of concentration reflects an intentional decision or simply how things accumulated.
