Daily options income strategy | The storage sector sees sharp volatility! SNDK rebounds after plunging 14%—is this a golden opportunity or just a technical bounce?

I. Market Barometer

On the previous trading day, the three major U.S. indices diverged: the Dow hit a new all-time high amid cooling nonfarm payroll data, while tech stocks faced profit-taking pressure, dragging down AI hardware and the storage sector collectively. $SanDisk (SNDK.US)$ It plunged over 14% in a single day to USD 1,745, with options premiums widening significantly amid heightened market volatility.

II. Focus on Hot Targets

SNDK: Plunges 14% in one day—post-panic sell-off recovery play for the storage sector leader

$SanDisk (SNDK.US)$ It closed down 14.13% at USD 1,745 on the prior session, hitting an intraday low of USD 1,693, with trading volume surging sharply and turnover reaching 11.87%, reflecting a shift in market sentiment to panic selling. The stock rebounded in pre-market trading above USD 1,800, rising more than 5%, indicating that panic sentiment is gradually subsiding.

From a technical perspective, SanDisk now exhibits a classic 'sell-the-news' sharp-decline pattern.After hitting a record high of USD 2,354, the stock has been in a continuous pullback and has already broken below its 30-day moving average. The RSI has rapidly retreated from overbought territory into neutral levels, and significantly increased volume indicates intense long-short turnover. In the short term, the stock is in a sharp-decline bottom-seeking phase; historical experience shows that such fundamentally driven emotional sell-offs often create a recovery window once panic has been fully released.

The primary driver behind this plunge is systematic profit-taking across the AI sector, not a deterioration in the company’s fundamentals.Investors have massively withdrawn capital from AI hardware leaders like NVIDIA and Micron, making SanDisk—a standout performer with a year-to-date gain exceeding 850%—a prime target for heavy selling. Further exacerbating sentiment, a major South Korean memory manufacturer announced a massive capacity expansion plan, and Meta revealed intentions to offload excess computing power, fueling additional market concerns.

However, Nomura Securities noted that South Korea’s investment plan—amounting to KRW 48 billion—will take at least 5–10 years to translate into actual production capacity, and the core issue facing the global memory industry remains severe supply shortages.

The company and Kioxia have officially announced the commencement of mass production of 10th-generation 3D NAND flash memory at their jointly operated Fab2 facility in Kitakami. This product leverages innovative CBA (Cell-Boost Architecture) technology, achieving breakthrough improvements in performance, capacity, and power efficiency, thereby providing critical technological support for high-performance memory demands in the AI era. Their joint venture agreement has been extended through December 2034, outlining a clear long-term capacity expansion roadmap.

Previously, Bernstein sharply raised its price target from $1,700 to $3,000, with the core rationale being a fundamental shift in the long-term agreement (LTA) model for memory chips. The new agreements feature fixed or range-based pricing, upfront financial commitments, and contract durations extended to three to five years, significantly reducing the risk of severe earnings volatility during industry downturns. The firm estimates that under extreme scenarios, fiscal year 2030 earnings per share could reach $214—2.6 times higher than the $81 projected under the old agreement model. Bank of America recently raised its target to $2,500, Citi also lifted its target to $2,500, and Susquehanna maintained its Wall Street-high target of $3,250.

III. Options Premium Collection Strategy

1. Cash Secured Put

Sell 1 contract of $SanDisk (SNDK.US)$ July 10, 2026, 1:50 PM ET; estimated required margin (for reference only): $135,000 ($1,350 × 100)

Opportunity Rationale:

For investors who believe in the long-term structural re-rating of NAND memory but have not yet established positions, short-term panic amid the upgraded LTA framework may present a rare entry window.

The new LTA model has fundamentally transformed earnings visibility in the memory industry. Buying outright at current levels carries the risk of further near-term sentiment-driven selling pressure. By selling put options, investors can collect elevated option premiums in this high-volatility environment if the stock stabilizes and recovers from current levels. If pessimism continues to spread and pushes the stock down toward the strike price, investors may also gain the opportunity to establish a long-term position at a significant discount.

2. Covered Call

Holding 100 shares $SanDisk (SNDK.US)$, sell 1 contract of SNDK 260710 2050C

Opportunity Rationale:

For investors already holding SanDisk positions and facing substantial paper losses, the stock has quickly retreated to the $1,700–$1,750 range due to sector rotation pressures. The market needs time to absorb sentiment-related disruptions. The long-term LTA logic and medium-to-long-term demand outlook underpinning Bernstein’s $3,000 price target remain unchanged despite the single-day plunge, though short-term overhead supply may constrain the pace of any rebound.

If investors remain confident in the company’s long-term value as a NAND leader and are unwilling to cut losses amid panic selling, yet worry that short-term sentiment and sector capital flows may continue to weigh on the stock, they can consider selling call options. If the stock consolidates near current levels, the premium income can gradually lower the cost basis. If sector sentiment subsequently recovers and pushes the stock up toward the strike price, this approach effectively realizes a phased profit-taking at a key technical resistance level.

IV. Risk Control Reminder

Although short-option strategies offer high win rates, investors must still implement proper risk management:

– Position management is key:The biggest risk for option sellers lies in black swan events. It is recommended that margin exposure for a single underlying should not exceed 20% of total capital. Never sell options beyond your capacity for the sake of greedy premiums.

– Timely rolling of covered call options: When a covered call option becomes deeply in-the-money (stock price far exceeds the strike price), and if the underlying stock is still viewed favorably, decisively 'roll' the position — that is, close the current option by buying it back and simultaneously sell an option with a later expiration date and a higher strike price to avoid having the stock called away at a low price.

– Cash-secured put options warn of 'left-tail risk':For cash-secured puts, if the stock price collapses due to deteriorating fundamentals (rather than a normal pullback), do not hold on stubbornly. At this time, stop losses should be executed, or 'rolling down' can be employed to buy time and wait for volatility to normalize.

Options Risk Disclosure

An option is a contract that grants the holder the right—but not the obligation—to buy or sell an underlying asset at a predetermined price on or before a specified date. Option prices are influenced by multiple factors, including the current price of the underlying asset, the strike price, time to expiration, and implied volatility. Implied volatility reflects the market’s expectation of future price fluctuations over the life of the option and is derived by reverse-engineering the Black-Scholes pricing model. It is commonly used as a gauge of market sentiment. When investors anticipate greater volatility, they may be willing to pay higher premiums for options to hedge risk, leading to elevated implied volatility. Traders and investors use implied volatility to assess the relative attractiveness of option prices, identify potential mispricings, and manage risk exposure.
