What happens when options on volatile stocks start trading? And why can't you plug in your own implied volatility on a trade? We tackle these and other questions in this weekend's Options Forum.

Shares of Tibco Software (TIBX Quote) started trading July 14. Options on Tibco started trading July 28. This is the first option trading that started within two weeks of an initial public offering that I have noticed. What are the conditions market makers typically look for to start option trading on a particular equity? Is there more to be read into such a quick start of option trading on this recent IPO of Tibco? -- Subodh Nijsure Subodh, On this question, we consulted Michael Bickford with the American Stock Exchange's derivative marketing and research division (also a Red Sox fan and therefore a hardy soul). He immediately pointed out that Tibco is a "spinoff from Reuters (RTRSY Quote), and there are different rules for trading for options of spinoffs than for straight IPOs." The Securities and Exchange Commission lets the option exchanges look back at the trading volume of the parent company and use that for historical comparison; that's why spinoffs are allowed to have options faster than regular IPOs, says Bickford. For a straight IPO, "it depends on how quickly the company meets trading volume and other criteria." As for market makers, "they don't decide when options start trading. Each exchange has a process to decide the stock selection. We here at the Amex have a committee of floor members and trading desks; we go through the universe of eligible companies [there are lots of them] and decide whether we should trade them. Though there are plenty of choices, lots of stocks don't trade actively, so it's difficult to make a deep, active options market for them." Thanks, Mike. Here's hoping Boston gets the wild-card spot.Trading Volatile Options
Would you please explain what happens when options are first listed on a rather volatile stock? Take Healtheon (HLTH Quote), for example. The Amex started listing options with strikes at 25, 30 and 35. So much is going on with that stock. The lockouts are ending, millions of new shares can be traded, etc. -- Frank Barish Frank, It's a guessing game, even for the pros. But wide spreads on prices are often the most obvious characteristic of an option on volatile stocks. We rang up Brent Houston, vice president of capital markets at his new job developing options trading for Datek Online in Edison, N.J. His answer:It goes back to implied volatility. Frank, you take historical volatility on the underlying stock (the amount the stock has moved up or down on an annualized percent basis), then apply that to classic options pricing models to determine your theoretical price. The two best-known models are Black-Scholes and Ross-Cox.From his days trading on the Pacific Exchange, Houston recalls friends on the trading floor "who've traded Yahoo! (YHOO Quote) and Amazon.com (AMZN Quote) who make the spread 2 points wide, even when it's an $8 option, partly because the stock would move so fast, they didn't have time to buy the stock and hedge the options they just traded. If you look at almost all the Internet stocks, for example, that would happen." Over time, ideally, the stock starts to settle down, and traders ratchet down the volatility percentage they plug into an options price. "As the stock starts trading more normally and with liquidity, then the spreads should narrow for the option prices," he adds. Advice? "I wouldn't enter a market order" for a new, volatile option. "Pick a price you feel comfortable with and don't keep chasing it. The option might come back down to the price you were looking for."
