The SpaceX Selling System I’d Use If I Held Your Shares

5 Takeaways
- SPCX has traded between $105 and $225 since listing. On 20,000 shares, that’s about $2.4 million of swing.
- Price targets move. “I’ll sell at $200” becomes $250 when the stock gets close.
- Most shareholders I meet sell off a price, a single number, or a gut call. None of those is a system.
- If I held your shares, I’d start with two numbers: a Secure Number and a Ride Band.
- Then I’d let two engines do the selling. Faster when the stock rises. Slower when it falls.
The First Thing I’d Fix
I sit across from SpaceX shareholders almost every week. The first thing I ask is: what’s driving your next sale?
A price? “I’ll sell at $200.” A number? “I need $800,000 for a house.” Or a gut call on the day the stock drops?
Most people know exactly what their shares are worth. Very few know what makes them sell. If I held your shares, that’s the first thing I’d fix.
Step 1: I’d Write Down My Secure Number
The after-tax dollars I’d want outside SpaceX, so my family’s life doesn’t depend on one stock. Three buckets:
- Obligations: taxes, debt, anything with a due date
- Life goals: the house, the business, the sabbatical
- Comfort capital: enough that I could stop checking the price
Composite example: $500,000 for debt and taxes, $800,000 for a down payment, $4 million in comfort capital. Secure Number: $5.3 million after tax.
Step 2: I’d Decide What Rides
Everything above the Secure Number is the Ride Band. The shares I’d keep because I believe in the company.
If you’re bullish, I’m not going to tell you to sell down to a 10% rule of thumb. I wouldn’t do that if these were my shares either. Secure what you need. Let the rest ride.
Step 3: I’d Let Two Engines Do the Selling
Monthly trim. A percentage of my shares every month, scaled to price. Higher price, bigger trim.
Milestone ladder. Set tranches at set prices. The stock clears a rung, a tranche goes.
If the stock rises, I reach my Secure Number faster. If it stalls or drops, I sell slower and keep more shares for the recovery. No guessing required.
Step 4: I’d Decide Now What a Sell-Off Changes
When SPCX slid toward $105 this summer, all bets were off. Rules got second-guessed, and most people froze.
So before the next one, I’d write down three things: my floor, how much my trim slows, and which rungs stay live.
Then I’d check the calendar: trading windows, the tax year (December 30 and January 2 are different years), and which share lots I’d sell first.
Three Questions I’d Answer This Week
- What’s my Secure Number, after tax?
- What rule makes my next sale happen?
- If SpaceX goes back to $105, does my plan still work?
If you can’t answer all three, that’s the conversation I’d want to have with you.
