June Office Hours FAQs: IV Statistics, Position Management, and the Wheel Strategy

What is the difference between IV Rank and IV Percentile?

Both statistics describe where current implied volatility (IV) sits relative to its history over the past year, but they measure different things. IV Rank compares current implied volatility to its 52-week high-low range — an IV Rank of 50 means implied volatility is halfway between the year's low and high. IV Percentile measures the share of trading days over the past year when implied volatility was lower than where it currently sits — an IV Percentile of 80 means implied volatility has been lower than the current level 80% of the time.

How can historical and implied volatility be compared?

Historical volatility measures how much the underlying has actually moved in the past, while implied volatility reflects what the market expects it to move in the future. When implied volatility rises meaningfully above its recent historical range, it can suggest market participants are anticipating an event or a larger move ahead, up or down. Charts that overlay the two are available on the options education website and can help frame whether option prices appear rich or cheap relative to past behavior.

How is a strike chosen when selling a covered call?

Strike selection involves a tradeoff between the premium collected and the willingness to sell shares at that strike if assigned. Closer-to-the-money strikes collect more premium but carry greater assignment risk, while further out-of-the-money strikes collect less premium with reduced assignment risk. There is no universal target percentage; the decision depends on each investor's outlook for the underlying and tolerance for being called away.

When can a covered call be rolled if the stock moves through the strike?

A covered call can be rolled up, out, or up and out by buying back the short call and selling a higher strike, a later expiration, or both. Waiting closer to expiration captures additional time decay before closing the short leg but leaves more room for the stock to continue rallying. The decision typically depends on the investor's outlook for whether the move is likely to continue or reverse.

Does the wheel strategy carry the same risk as a covered strangle?

No. The wheel strategy rotates between a cash-secured put and a covered call, typically holding 100 shares of the underlying per options contract. A covered strangle begins with 100 long shares while simultaneously selling a cash-secured put and a covered call. If the put is assigned, the position grows to 200 shares, doubling the downside exposure compared to the wheel.

What are the tradeoffs between a 21-day and a 41-day put spread for collecting premium?

Each carries tradeoffs. The longer-dated spread collects more premium upfront, while the shorter-dated spread benefits more rapidly from accelerated Theta decay near expiration. Selling consecutive shorter-dated spreads can capture decay twice within the same window covered by a single longer-dated trade, though it requires more active position management.

How does Delta relate to the risk of an options position?

Delta measures how closely an option's price tracks the underlying. Higher-Delta options behave more like stock and respond more strongly to price moves, which translates into greater exposure for a seller. Delta is also commonly referenced as an approximation for the probability that a contract will finish in-the-money, providing context for option sellers evaluating assignment risk.

How long after the market close can a short option still be assigned?

For American-style options, all exercise notices must reach OCC (The Options Clearing Corporation) by 5:30 p.m. ET on expiration day. Individual brokerage firms set their own earlier cutoff times for clients, typically ranging from 15 to 45 minutes after the 4:00 p.m., ET close. Because after-hours price movement can prompt exercise notices on contracts that closed out-of-the-money, assignment risk for short options continues beyond the regular session close.

How is Theta priced into options heading into a long weekend?

Market participants often begin pricing in a weekend's expected time decay during the final trading session rather than waiting for it to occur over the actual weekend. As a result, option premiums on the Friday before a long weekend may already reflect Monday's theoretical values, along with corresponding adjustments to Delta and Gamma.
