Hi Andrew,

Welcome to the thread. Your questions about the VXN and VIX are not naive at all. They are indeed measures of internal volatility and I can think of two reasons why they're useful:

First, at their extremes, they're good general indicators of turns in their respective indices. There's a saying that "when the VIX is low, it's time to go, when the VIX is high, it's time to buy". High VIX and VXN numbers generally signify market bottoms, which are marked by great volatility. What is "high enough" is subject to interpretation, particularly with regard to the VXN, which is a new measure.

In practical terms with regard to options trading, there are a number of factors built into the price of each option: the price of the underlying stock, the prevailing interest rate,the amount of time till expiration, and the IV. When the internal volatility of the stock is high, premiums on both puts and calls are inflated. It's not a great time to buy them, because you'll be paying a high price. What may happen is something referred to as a "volatility implosion" if the stock price begins to calm, the IV dwindles and the premium of the option you're holding will deflate, even though the underlying is not moving much.

What options traders like to do in times of high VXN and VIX numbers is to sell premium, ie, sell naked puts on issues they think will rise, sell naked calls on issues they think will fall (which is extremely risky), and sell calls against stocks they own (a/k/a writing covered calls). In this way, the premium seller has the market working for him or her in three ways: you are trading in the general direction of the market, you areprofiting from the natural decay in time value of the option as you near expiry,and you are profiting from the deflation in volatility.

I hope this answers your question. Please feel free to ask others.
