Understanding Implied Volatility and Expected Range of Stocks

The video tutorial explains how to calculate the expected range of a stock's price using implied volatility and confidence levels. It covers the concept of implied volatility, its impact on option prices, and provides examples of calculating expected price ranges for stocks XYZ and ABC. The tutorial also reviews the standard normal distribution and how to adjust confidence levels for different standard deviations.

What happens to option prices when implied volatility increases?

• Option prices remain the same

• Option prices become unpredictable

• Option prices decrease

• Option prices increase

If a stock is trading at $100 with an implied volatility of 20%, what is the expected price of a 110 call option?

• $1.50

• $2.73

• $1.00

• $3.00

Which formula is used to calculate the expected range of a stock with a 68% confidence level?

• Stock price divided by implied volatility

• Implied volatility times square root of stock price

• Stock price times implied volatility times square root of days to expiration divided by 365

• Stock price times implied volatility

In the example with a stock price of $200 and 30% implied volatility, what is the expected range of the stock price within one year?

• $140 to $260

• $100 to $300

• $180 to $220

• $150 to $250

For a stock with a 30-day option and 42% implied volatility, what is the expected range of the stock price?

• $120.00 to $180.00

• $130.00 to $170.00

• $131.94 to $168.06

• $140.00 to $160.00

What is the probability that a stock's price will fall within one standard deviation of the mean in a standard normal distribution?

• 99.7%

• 50%

• 68%

• 95%

How does the confidence level change when calculating the expected range within two standard deviations?

• It increases to 95%

• It remains at 68%

• It increases to 99.7%

• It decreases to 50%

What is the area under the curve for a standard normal distribution?

• 0.5

• 1

• 0.95

• 0.68

For a 99.7% confidence level, how many standard deviations from the mean should be considered?

• Four

• Two

• One

• Three

What is the expected range of a stock's price for a 95% confidence level?

• Within one standard deviation

• Within four standard deviations

• Within two standard deviations

• Within three standard deviations
