The CBOE normally sets the strike prices for its options so that they are spaced $, $5 or $10 apart. Stocks at lower prices have smaller spaces between strike prices. When options with a new expiration date are introduced, the CBOE usually introduces two or three options with strikes nearest to the current stock price. If the price moves outside this range, new strikes may be introduced. For example, if new October options are offered on a stock currently priced at $84, then options striking at $80, $85 and $90 might be created. If the price rises above $90, a new strike at $95 might be introduced
