Markets are tumbling - time to sell premium

Options are complex, high-risk products and require knowledge, investment experience and, in many applications, high risk acceptance. We recommend that before you invest in options, you inform yourself well about the operation and risks.
Markets are tumbling - time to sell premium?
Yesterday was brutal for the markets. The S&P 500 (SPX) dropped 2.7%, and the Nasdaq 100 (NDX) fell 3.8%. While it’s not a full-blown crash, it certainly feels like one for many traders. When markets sell off aggressively, fear spikes, and so does volatility.
But here’s the opportunity: high volatility means high option premiums. And when premiums are high, selling options is often more attractive than buying them. Let's break this down and explore an options strategy that benefits from this environment.
What does selling premium mean?
In options trading, you can either buy premium or sell premium:
- Buying premium means purchasing options, hoping for a large market move so that the option increases in value. This benefits from rising volatility.
- Selling premium means selling options (or option spreads) to collect income, profiting from time decay and potentially falling volatility.
When volatility is high, option prices are inflated. This makes selling premium more attractive, as the options you sell are worth more than usual. If volatility declines, those options become cheaper, and as the seller, you can buy them back for less or let them expire for a profit.
XSP – the S&P 500 Mini Index
To illustrate this concept, we’ll take a look at XSP, the Mini S&P 500 Index option, which is one-tenth the size of SPX. It tracks the S&P 500, just like SPX options, but with some important differences.
Unlike SPY, which is an ETF (exchange-traded fund) that physically holds the stocks of the S&P 500, XSP is an index option, meaning it is purely a derivative based on the S&P 500 index level. This leads to some key advantages:
- XSP is cash-settled, meaning there’s no risk of getting assigned shares. SPY options, on the other hand, settle in stock, which can be a concern for traders who don’t want to take on an actual stock position.
- XSP options are European-style, meaning they cannot be exercised early. SPY options are American-style, which means assignment can happen at any time before expiration, particularly around dividend dates.
- No dividend risk with XSP. Since SPY holds actual stocks, dividends impact its option pricing, whereas XSP options are unaffected.
If you trade SPX but want smaller contract sizes, or if you trade SPY but want to avoid assignment risk, XSP is a great alternative.
Volatility is high—a seller’s market for options
Now that we’ve established what XSP is, let’s look at why it’s an attractive options trading instrument right now.

- Implied volatility is at 23.29, while historical volatility (HV) is at 19.03. This means that the market is pricing in more future movement than has actually occurred.
- IV Rank (implied volatility rank) is at 76.06, meaning that the current implied volatility is in the 76th percentile of the last year, indicating that options are significantly more expensive than usual.
When implied volatility is higher than realized (historical) volatility, it suggests that options are overpriced relative to actual market movement. This is often seen as a reason to sell volatility, as implied levels tend to mean-revert back toward realized volatility over time. If IV drops, option prices decline, benefiting premium sellers.
This is the kind of environment where selling premium-based strategies makes sense. That’s where the iron condor comes in.
An iron condor – selling volatility in a high-premium market
Since IV is high and above historical volatility, we want to sell options rather than buy them. One strategy that works well in this scenario is the iron condor—a neutral, range-bound strategy that benefits from time decay and declining volatility.
Iron condor setup (XSP)
Here’s an example trade showing a possible iron condor setup:
- Sell 580 call
- Buy 585 call
- Sell 550 put
- Buy 545 put
- Expiration: March 21, 2025
Premium received: $272
Max loss: $228
Break-even points: 547.28 and 582.72
Why this trade?
This trade is based on a range-bound outlook, meaning that we expect the S&P 500 to remain within a certain price range rather than make a significant move up or down.
- Volatility is high, so premiums are rich – we collect a high premium, increasing our probability of profit.
- XSP is still range-bound, despite the drop – the market has sold off, but unless we expect a continued breakdown or rapid recovery, a consolidation is likely.
- We profit if XSP stays between 550 and 580 by expiration – the goal is for time decay (theta) to work in our favor while volatility cools off.
- IV is higher than HV, meaning we are selling options at inflated prices that could revert lower.
However, if you expect the S&P 500 to continue declining in the next 10 days or to strongly rebound, this strategy would not be ideal. In that case, you should look at other strategies that are better suited for trending markets.

Defined risk vs. undefined risk—why choose an iron condor?
An iron condor is a defined risk strategy, meaning you know upfront the maximum possible profit and loss before entering the trade. This makes it a safer choice compared to an undefined risk strategy like selling a strangle, which has a higher potential reward but also unlimited downside risk.
A strangle involves selling an out-of-the-money call and put, without buying protective options. While this can generate larger premiums than an iron condor, the risk is significantly higher. If the market moves aggressively in either direction, losses can be catastrophic, potentially far exceeding your account size if not properly managed.
In contrast, an iron condor has a built-in hedge because it consists of two credit spreads:
- A bear call spread (selling a call and buying a higher strike call)
- A bull put spread (selling a put and buying a lower strike put)
This structure caps both potential profits and losses, making risk management far easier.
How to calculate the max risk?
The maximum risk on an iron condor is calculated as:
Max risk = width of the wings – premium received
In the example trade:
- The width of the wings is 5 points (difference between short and long strikes)
- The premium received is $2.72 (or $272 per contract)
So the max possible loss per contract is:
$5.00 – $2.72 = $2.28 (or $228 per contract)
Taking profits early to increase consistency
A common approach when trading iron condors is to take profits before expiration rather than waiting for the full premium. Many traders use a profit target, such as closing the position when 50-60% of the maximum profit is reached.
For example, if the premium collected is $272, a trader might place a closing order to buy back the spread once they can keep around $160 of profit. This approach increases consistency by avoiding unpredictable late-stage market moves that could turn a winning trade into a loss.
Final thoughts: sell volatility while it’s high, but stay flexible
The market selloff has spiked implied volatility, making this an excellent time for selling premium-based strategies like iron condors. But as always, you must align the trade with your market outlook and manage risk accordingly.
Do your own due diligence before placing any trades.
