A New Way to Quantify Fear >

THE SCENE: A midtown Manhattan restaurant. Two old friends meet for lunch to discuss market events.

Barron's: It must be hard having your efficacy questioned, especially as you haven't been behaving as expected lately.
VIX, the famed volatility index: It isn't easy being the most successful options-sentiment indicator ever created.

Barron's: Do you have a perception problem?
VIX: I see just fine.

Barron's: Then you won't mind getting new competition Monday, when the Credit Suisse Fear Barometer -- the CSFB -- is unveiled.
VIX: C'est la guerre.

Barron's: The markets are warlike, and yet New York is like a small town. How funny that CSFB's creators, Dennis Davitt and Edward K. Tom -- who run Credit Suisse's equity-derivatives trading and strategy, respectively -- chose the same restaurant. (VIX magnanimously rises to invite his adversaries to dine.)
VIX: We were just discussing the new CSFB. Can you elaborate?
Tom: Our indicator answers a simple question. If an investor will forgo upside returns above 10%, what is the deductible before a Standard & Poor's 500 portfolio can be fully insured?
VIX: You mean selling an out-of-the-money index call and buying an out-of-the-money put to hedge a stock portfolio?
Davitt: Exactly. VIX wasn't designed to measure fear. VIX measures 30-day market expectations for volatility, which is associated with, but not always correlated to, fear.
VIX: Say it, Double-D.
Tom: CSFB quantifies fear by measuring "zero-premium collars" that expire in three months, rather than VIX's 30 days.
Davitt: Here is another major difference. Say there is a massive Standard & Poor's 500 call bid. That indicates investor confidence, but the bid could cause call implied volatility to increase, making VIX rise, not fall.

Barron's: But upside and downside risk is elemental. That is why zero-cost collars are always packed with information. So what is CSFB saying, and how do we use it?
Tom: Say, for example, the S&P is at 855, and CSFB is at 13.68%. [If SPX changes, that percent changes.] That means if you are long the Standard & Poor's 500, you can initiate a zero-cost collar by selling a July 940 Standard & Poor's call that is 10% out-of-the-money, and buying a July 738 put that is 13.68% out-of-the-money. This implies investors are expressing relatively low levels of downside fear for the next three months.

Barron's: OK, but 13.68% still seems random.
Tom: Think of 13.68% (or any CSFB level) as an insurance deductible. It is how much the put is out-of-the-money. The market has to drop 13.68% before it kicks in.

Barron's: So if CSFB registers a high level like 20%, investors are afraid, and insurance is more expensive. If CSFB is low, insurance is cheap, and investors aren't.
Davitt: Right. We backcast CSFB to 1998. It is ranged from an October 2008 low of 10.5% to a March 2007 high of 30%.
VIX: Interesting...However, I'm ubiquitous.
Davitt: We have desk real estate, too. Enter "CSFB Index Go" on Bloomberg.

Barron's: Well, who'd have ever thought there'd be a bull market for fear?
