Calls: 0 to 1. Puts: -1 to 0
Theta
Time decay — how much value lost per day
Always negative for buyers (options lose value daily)
Gamma
Rate of change of delta
Higher near ATM and expiration
Vega
Sensitivity to implied volatility changes
Higher volatility = more expensive options
Rho
Sensitivity to interest rate changes
Usually minor

Basic Option Strategies (Beginner-Friendly)
1. Covered Call (Conservative Income)
Item
Details
Setup
Own 100 shares of stock + sell 1 call option
Goal
Earn premium income on stock you already own
Risk
Stock could drop (same as owning stock); upside capped
Example
Own 100 shares XYZ at $100, sell $110 call for $3
Max profit
$13/share ($10 appreciation + $3 premium)
Max loss
$97/share (stock goes to $0, but you keep $3 premium)
Ideal for
Income on existing holdings, slightly bullish outlook
2. Cash-Secured Put (Buy Stock at a Discount)
Item
Details
Setup
Sell 1 put option with cash to cover purchase
Goal
Collect premium OR buy stock at a lower price
Risk
Must buy 100 shares if stock drops below strike
Example
Sell XYZ $95 put for $3, hold $9,500 cash
If stock stays above $95
Keep $300 premium, free money
If stock drops to $90
Buy 100 shares at $95, effective cost $92 ($95 - $3 premium)
Ideal for
Wanting to buy a stock at a lower price
3. Protective Put (Insurance)
Item
Details
Setup
Own 100 shares + buy 1 put option
Goal
Protect against downside while keeping upside
Risk
Cost of premium if stock doesn’t drop
Example
Own 100 shares at $100, buy $95 put for $3
Stock drops to $70
Sell at $95 (loss limited to $8/share)
Stock rises to $120
Great — profit is $20/share minus $3 premium = $17
Ideal for
Protecting concentrated positions

Why It’s Costly
Buying far OTM options
Very cheap but almost always expire worthless
Trading weekly expirations
Extreme time decay, near-gambling
Not understanding assignment
You may be forced to buy/sell shares
Ignoring implied volatility
High IV = expensive premiums (after earnings, etc.)
Overleveraging
Small move against you = large % loss
Holding through expiration
Time decay accelerates near expiration
Trading on tips/memes
Following social media trades without understanding
No exit plan
Not knowing when to take profit or cut losses
