File 1: batch-27-how-to-start-investing-with-500.md

Issue: Compound math error — $100/month at 10% figure is wrong

Location: Section "What $500 Can Actually Do: The Compound Math"

Quote in article:

"If you invest $500 today and add just $100 per month, the 30-year outcome at 7% annual return grows to over $120,000. At 10%, it's closer to $215,000."

Problem:
The 10% figure is materially incorrect. Using monthly compounding at 10%/12 per month over 360 months:

• FV of $100/month annuity: ≈ $226,000
• FV of $500 lump sum: ≈ $9,960
• Correct total: ≈ $235,967

The article states "closer to $215,000" — this is off by ~$21,000 (~9% error). The 7% figure ("over $120,000" vs. actual ~$126,000) is fine — directionally accurate and conservative.

The lump-sum table (no monthly contributions) is correct throughout.

Fix:
Change "At 10%, it's closer to $215,000" to "At 10%, it's closer to $235,000."

File 4: batch-27-what-is-covered-call-strategy.md

Issue: Qualified covered call definition is technically inaccurate

Location: Section "Tax Implications: It's More Complex Than It Looks"

Quote in article:

"The IRS has specific rules around 'qualified covered calls' — calls that are at or out of the money and have standard expiration periods."

Problem:
The characterization of qualified covered calls as requiring the strike to be "at or out of the money" is incorrect. Under IRC Section 1092(c), a qualified covered call is defined as one that is not deep in the money — the IRS uses tiered tables based on time to expiration and stock price to determine the minimum permissible strike. Slightly in-the-money calls can still qualify, depending on the applicable tier. Saying "at or out of the money" overstates the restriction and misrepresents the rule.

While the practical effect is conservative (readers will avoid writing any in-the-money calls, which is the safer behavior), the definition as written is factually wrong and could mislead a reader who looks up the actual rule and finds the characterization doesn't match IRS guidance.

The broader tax section is otherwise accurate: holding period suspension for in-the-money calls, premium recognition at expiration/assignment as short-term gain, and the recommendation to use tax-advantaged accounts are all correct.

Fix:
Replace: "calls that are at or out of the money and have standard expiration periods"
With: "calls that are not deep in the money (the IRS uses specific tiered tables based on strike price relative to the stock price and time to expiration to define this threshold) and have more than 30 days to expiration"

Alternatively, simplify to: "calls that satisfy the IRS's 'not deep in the money' test — the exact threshold depends on the stock's price and time to expiration; generally, at-the-money or out-of-the-money calls qualify, but slightly in-the-money calls may qualify too depending on those factors"
