How Options Are Priced

(It’s Not Just About Direction) Part 2

Most beginners think options are simple:

If the stock goes up, a call makes money.

If it goes down, it doesn’t.

But that’s incomplete.

Because options are not just about direction.

They are about probabilities and expectations.

What You’re Really Buying

When you buy an option, you’re buying:

→ The probability that something happens before a certain date.

That probability is reflected in the price.

The Key Drivers of Option Prices

There are four main factors:

1. Stock Price

The closer the stock is to your strike price, the more valuable the option.

2. Time to Expiry

More time = more opportunity for the move to happen.

So:

→ More time = higher price

3. Volatility

This is one of the most important — and most misunderstood — factors.

Higher volatility means:

→ Larger potential price swings
→ Higher probability of hitting your target

So options become more expensive.

4. Interest Rates (Minor but relevant)

Rates slightly influence pricing, especially over longer durations.

Why Volatility Matters So Much

You can be right about direction — and still lose money.

Example:

You buy a call expecting a big move.

The stock goes up slightly.

But volatility drops.

→ The option loses value anyway.

This is why options are not just directional bets.

They are bets on magnitude and uncertainty.

Implied Expectations

Options prices reflect what the market expects.

If everyone expects a big move:

→ Options are expensive.

If expectations are low:

→ Options are cheap.

Sound familiar?

It’s the same concept you’ve seen in stocks.

Markets price expectations — not reality.

Final Thought

Options pricing is not about guessing direction.

It’s about understanding:

• Probability
• Time
• Volatility

And how those interact.
