Four Numbers (Beyond the Stock Price) Every Executive Should Know Before Selling
Most executives spend years focused on one number:
The stock price.
Every morning starts the same way.
Coffee.
Email.
Stock price.
Then pretending you're checking Bloomberg for "the markets" when you're really checking your stock.
But when it's finally time to sell, the stock price is often the least important number in the equation.
I've met executives who could tell me exactly what their company's shares closed at three Tuesdays ago, yet had absolutely no idea how much of the sale would end up in their own checking account.
Before you place a sell order, understand these four numbers.
1. Your Cost Basis
This is where reality begins.
Your cost basis is generally what you paid for the shares, adjusted for various tax events. It's the number the IRS uses to calculate your taxable gain when you sell.
Many executives assume they know their basis.
Then they discover a transfer from 2009, a stock split, an ESPP purchase, an old brokerage account, or a merger that turned what looked like simple math into an archaeological dig.
Selling stock without knowing your basis is like selling your house without remembering what you paid for it.
It's exciting right up until tax season.
Before selling, ask yourself:
Do I know my adjusted cost basis?
Has my broker reported it correctly?
Are there older shares or transfers that need to be verified?
This number determines how much of the proceeds belong to you...
...and how much gets donated to our dear Uncle in Washington.
2. Your Unrealized Gain
This one sounds simple.
How much have you actually made?
Not just in dollars.
As a percentage of your portfolio.
As a percentage of your net worth.
As a percentage of your future retirement.
A $500,000 gain can either be life-changing...
...or Tuesday.
Context matters.
Understanding your unrealized gain helps answer questions like:
Is this the right time to diversify?
Would spreading sales across multiple years help?
Am I taking more risk than I realize?
Sometimes clients tell me,
"I don't want to pay the taxes."
Neither do I.
Nobody has ever walked into my office hoping to maximize their tax bill.
But sometimes paying taxes is simply evidence that you've made a lot of money.
The bigger mistake is letting the tax tail wag the investment dog.
3. Your Marginal Tax Rate
This is where perfectly intelligent people accidentally write very large checks.
Selling appreciated stock doesn't happen in a vacuum.
One transaction can affect:
Federal capital gains taxes
State taxes
NIIT
Medicare premiums
Estimated tax payments
Other income-based tax calculations
Think of your tax return like Jenga.
Pull one block...
...and suddenly everything else moves.
The goal isn't paying zero tax.
If you're looking for that, you'll probably end up buying a very expensive tax strategy from someone driving a very expensive car.
The goal is paying only what you legally owe.
No more.
No less.
4. Your Concentration Risk
Here's my favorite question.
"What percentage of your investments are in your company's stock?"
The most common answer?
"...I have no idea."
Then we calculate it.
Sometimes it's 45%.
Sometimes it's 70%.
Sometimes it's high enough that I quietly ask whether they know they're already employed there.
Your paycheck depends on the company.
Your bonus depends on the company.
Your future promotions depend on the company.
Your health insurance probably depends on the company.
Does your retirement need to depend on the company too?
Diversification isn't an insult to your employer.
It's simply acknowledging that history is full of outstanding companies that eventually became outstanding case studies.
The Bigger Picture
Selling company stock isn't really about taxes.
It's about turning concentrated wealth into lasting wealth.
Taxes matter.
Investment strategy matters.
Retirement matters.
Estate planning matters.
Most importantly...
You only get one chance to diversify before everyone else realizes your stock is no longer worth what it was yesterday.
Final Thoughts
Before you sell your next share, ask yourself:
Do I know my cost basis?
Do I understand my unrealized gain?
Have I calculated the tax impact?
How concentrated is my overall portfolio?
If you can answer all four confidently, you're making decisions from a position of knowledge rather than emotion.
If you can't, thank you for your generous contribution toward reducing the national debt.
The Treasury appreciates your enthusiasm.
