Understanding the Basics of Options
At its core, an option functions like a "reservation deposit" in financial markets. Let's break this down with a real-world example:
The Tuna Fishery Analogy
During tuna season, a buyer named Daichi pays a fisherman ¥2,000 as a deposit to secure a contract: "On May 1st, I can buy one tuna for ¥10,000."
Two scenarios may unfold:
- Market Price Drops to ¥5,000
Daichi abandons the contract (losing his ¥2,000 deposit), while the fisherman profits ¥2,000. - Market Price Soars to ¥50,000
Daichi exercises his right to buy at ¥10,000, sells at market price for ¥38,000 profit. The fisherman loses ¥38,000.
This demonstrates a call option (buying right). Key takeaways:
- Buyer (Long Position): Pays premium for the right to transact
- Seller (Short Position): Obligated to fulfill if exercised
- Premiums are non-refundable regardless of exercise

Put Options Explained
Reverse the roles: The fisherman pays ¥2,000 to secure the right to sell tuna at ¥10,000 later.
- If market rises to ¥20,000: Fisherman abandons (loses deposit)
- If market falls to ¥5,000: Fisherman profits ¥5,000 (¥10,000 sale vs. market price)
Core Trading Strategies Visualized
Four Fundamental Positions
| Strategy | Max Profit | Max Loss | When to Use |
|---|---|---|---|
| Buy Call | Unlimited upside | Premium paid | Expecting major rally |
| Sell Call | Premium received | Unlimited upside | Neutral/bearish outlook |
| Buy Put | Unlimited downside | Premium paid | Anticipating crash |
| Sell Put | Premium received | Unlimited downside | Bullish/range-bound |
Why Sellers Participate
While buyers enjoy limited risk/unlimited reward, sellers win more frequently:
- A ¥10,000 call with ¥2,000 premium only profits buyers above ¥12,000
- Sellers keep premiums if price stays below ¥12,000 (wider profitable range)
