Introduction: Dual-Purpose Cash-Secured Puts
Most traders think of cash-secured puts as simply a way to collect premium. But when
used strategically, this options strategy serves a dual purpose: generating consistent
weekly income while simultaneously lowering your overall cost basis through planned
assignments.
In this guide, we'll walk through real-world examples of cash-secured put assignments on
Novavax Inc. (NVAX) and Rumble (RUM), demonstrating how to track these positions,
process assignments, and leverage the cost basis tracking features on MyATMM.com to make
informed trading decisions.
Key Strategy: Selling at-the-money cash-secured puts weekly maximizes
premium collection while strategically building positions at lower cost basis levels
through assignments.
Understanding the Cash-Secured Put Strategy
What Are Cash-Secured Puts?
A cash-secured put is an options strategy where you sell a put option contract while
setting aside enough cash to purchase 100 shares of the underlying stock if assigned.
This strategy generates immediate premium income and positions you to acquire stock at a
predetermined price.
The Dollar Cost Averaging Advantage
When you're assigned on a cash-secured put, you purchase shares at the strike price. If
you already own shares at a higher price, this assignment lowers your average cost per
share—a form of dollar cost averaging that's both strategic and premium-generating.
Example Scenario:
-
Current Position: 300 shares at $25.00 cost basis ($7,500
total)
- Put Assignment: 100 shares at $11.00 strike ($1,100 total)
-
New Average Cost: 400 shares at $21.50 cost basis ($8,600
total)
-
Benefit: Lowered cost basis by $3.50 per share while collecting
premium
Why Weekly Options?
Weekly options provide several advantages for this strategy:
-
Higher Time Decay: Options decay faster in the final week, allowing
you to capture more time value relative to the holding period
-
Flexibility: Weekly cycles allow rapid adjustment to market
conditions
-
Consistent Cash Flow: Weekly expirations create regular income
opportunities
-
Lower Commitment: Shorter timeframes mean less capital tied up per
contract
Real Trading Example: Rumble (RUM) Assignment
Initial Position Analysis
Let's examine a real cash-secured put assignment on Rumble (RUM) and how it impacted the
overall position cost basis.
RUM Position Before Assignment:
- Current Cost Basis: $10.70 per share
- Existing Position: 300 shares
- Put Contract Details: $7.50 strike, weekly expiration
- Stock Price at Assignment: Below $7.50 (in-the-money)
Processing the Assignment
When the put expired in-the-money, the assignment process involved several steps that
MyATMM's cost basis tracking made simple:
-
Navigate to Cost Basis Screen: Access the ticker's detailed
position view
-
Locate the Expired Put: Find the $7.50 strike put that expired on
Friday
-
Select Assignment Action: Choose "Assign" from the dropdown menu
-
Confirm Assignment Details: 100 shares purchased at $7.50 strike
price
-
Generate Transaction Record: Create the buy-to-open stock
transaction at $7.50
- Update Position: Move the transaction to permanent history
Cost Basis Impact
The assignment resulted in a significant cost basis reduction:
RUM Cost Basis Change:
Before Assignment: $10.70 per share (300 shares)
After Assignment: $10.17 per share (400 shares)
Reduction: $0.53 per share decrease in cost basis
Strategic Positioning
With the stock trading at $6.44 following the assignment, the cost basis of $10.17 might
seem concerning. However, this creates the perfect setup for the next strategic move:
-
Sell Another Cash-Secured Put: Target the $6.00 strike for the
upcoming week
-
Collect Additional Premium: Generate income while stock is below
cost basis
-
Lower Collateral Requirement: Only $600 collateral needed for $6
strike
-
Further Cost Basis Reduction: If assigned, cost basis drops even
further
Real Trading Example: Novavax (NVAX) Assignment
Initial Position Status
The Novavax position demonstrated an even more dramatic cost basis improvement through
strategic put assignments.
NVAX Position Before Assignment:
- Current Cost Basis: $25.00 per share
- Existing Position: 300 shares
- Put Contract Details: $11.00 strike, expired December 11
- Stock Price at Expiration: $9.65 (well in-the-money)
Assignment Workflow
Processing the NVAX assignment followed the same systematic approach:
-
Identify the Expired Put: Located the $11.00 strike put that
expired below the strike price
-
Execute Assignment: Selected "Assign" from dropdown, confirmed 100
shares at $11.00
-
Generate Transaction Record: Created buy-to-open stock entry for
assignment
-
Clean Up Proposed Records: Removed temporary calculation entries
-
Finalize Transaction: Moved completed transaction to permanent
history
Significant Cost Basis Improvement
The NVAX assignment demonstrated the power of this strategy for high-cost-basis
positions:
NVAX Cost Basis Transformation:
Before Assignment: $25.00 per share (300 shares = $7,500 total)
After Assignment: $22.46 per share (400 shares = $8,984 total)
Reduction: $2.54 per share decrease in cost basis (10.2% improvement)
Continuing the Strategy
With the stock trading at $9.65 and a cost basis of $22.46, multiple strategic options
emerge:
-
Sell Additional Puts: Target $9.50 or $9.00 strikes for weekly
premium
-
Collect High Premium: High cost basis allows aggressive covered
call strikes
-
Continue Dollar Cost Averaging: Each assignment further lowers the
average cost
-
Plan Breakeven Exit: Calculate exact strike prices needed to exit
at breakeven including all collected premiums
Leveraging MyATMM for Cost Basis Precision

Best Practices for Cash-Secured Put Dollar Cost Averaging
Strike Selection Strategy
Choosing the right strike prices balances premium income with assignment probability:
-
At-the-Money Strikes: Maximum premium collection, 50% probability
of assignment
-
Slightly Out-of-the-Money: Good premium with lower assignment risk
-
Deep Out-of-the-Money: Lower premium but higher probability of
expiring worthless
-
Cost Basis Considerations: If your goal is to lower cost basis,
favor strikes more likely to be assigned
Capital Management
Effective cash-secured put selling requires disciplined capital allocation:
Capital Allocation Guidelines:
- Never commit more than 5-10% of portfolio to a single ticker
- Maintain cash reserves for assignment requirements
- Scale into positions gradually (don't sell all contracts at once)
- Reserve capital for additional puts if assigned
- Consider collateral requirements: Lower strikes need less capital
When to Accept Assignment vs. Roll
Not every in-the-money put should be allowed to assign. Consider rolling instead when:
-
Temporary Price Dip: Stock fell briefly but you expect recovery
-
Better Premium Available: Rolling out and down generates more
premium than assignment
-
Capital Constraints: You don't want to tie up additional capital
-
Cost Basis Already Low: Further lowering wouldn't provide strategic
benefit
Accept assignment when:
-
High Cost Basis Position: Assignment significantly lowers average
cost
- Long-Term Bullish: Happy to own more shares at this price
-
Wheel Strategy Active: Planning to sell covered calls against new
shares
-
Rolling Premium Insufficient: Not enough credit to make rolling
worthwhile
Premium Reinvestment Strategy
Consider how to deploy premium collected from puts:
-
Reserve for Assignments: Hold premium as collateral for future
assignments
-
Reinvest in New Positions: Use premium to fund puts on other
tickers
-
Reduce Overall Cost: Apply premium to reduce net capital committed
- Build Cash Buffer: Maintain liquidity for market opportunities
Advanced Strategy Considerations
Planning Your Exit Strategy
Before entering any cash-secured put position, plan your eventual exit:
Exit Planning Questions:
- At what cost basis will I consider this position successful?
- What total premium needs to be collected to achieve breakeven?
- At what strike price can I sell covered calls profitably?
- How long am I willing to hold this position?
Covered Call Transition
Once you've built a position through put assignments, transition to covered calls:
-
Calculate Breakeven: Determine what call strike covers your cost
basis plus collected premium
-
Premium Collection: Continue generating income while holding shares
-
Bilateral Trading: Sell puts when assigned, sell calls when stock
recovers
- Wheel Strategy: Continuously cycle between puts and calls
Tax Implications
Be aware of the tax treatment for cash-secured puts:
-
Premium Income: Treated as short-term capital gain when put expires
worthless
-
Assignment Impact: Strike price becomes cost basis; premium reduces
overall cost
-
Holding Period: Assignment starts a new holding period for tax
purposes
- Wash Sale Rules: Consider implications when realizing losses
Note: Always consult with a qualified tax professional regarding your specific
situation.
Risk Management
While this strategy is conservative, risks still exist:
Key Risks to Monitor:
-
Downside Risk: Stock can decline significantly below your cost
basis
-
Opportunity Cost: Capital tied up while better opportunities
emerge
-
Dividend Risk: Early assignment possible before ex-dividend
dates
-
Liquidity Risk: Difficult to exit or roll in illiquid
underlyings
- Black Swan Events: Unexpected news can crater stock prices
Real Results: What This Strategy Achieves
Income Generation
The primary benefit of weekly cash-secured puts is consistent income:
Weekly Premium Targets:
-
Conservative (1-2% weekly): Out-of-the-money puts on stable
stocks
- Moderate (2-3% weekly): At-the-money puts on quality names
-
Aggressive (3-5% weekly): At-the-money puts on volatile stocks
Percentages based on collateral required, not total portfolio value.
Cost Basis Reduction
Strategic assignments create meaningful cost basis improvements:
- RUM Example: 5.0% cost basis reduction ($10.70 to $10.17)
- NVAX Example: 10.2% cost basis reduction ($25.00 to $22.46)
-
Compounding Effect: Multiple assignments create exponential
benefits
- Premium Offset: Collected premium further reduces net cost
Position Building
This approach allows systematic position accumulation:
- Build positions gradually without large capital outlay
- Dollar cost average automatically through assignments
- Get paid to accumulate shares (via premium collection)
- Control position sizing with strike and contract selection

Risk Disclaimer
Options trading involves significant risk and is not suitable for all investors.
Cash-secured puts obligate you to purchase shares at the strike price if assigned, which
can result in substantial losses if the stock declines significantly. Past performance
does not guarantee future results.
