How does Vega affect option prices?
Could you please elaborate on how Vega, the measure of an option's sensitivity to changes in volatility, influences the pricing of options? Specifically, how does an increase or decrease in Vega affect the value of an option contract? Is there a direct correlation between Vega and the underlying asset's volatility, and how does this impact option traders' strategies and risk management? Additionally, could you provide an example to illustrate the relationship between Vega and option prices in a practical scenario?
