Ride-the-Wave Strategy – Best for Stock Traders

Ride-the-Wave targets multi-day price momentum following a company’s earnings announcement (EA). With this strategy:

  1. Buy a stock one day post-EA if a stock reacts positively post-earnings:
    1. Near the close of trading the EA-day for a pre-market-EA
    2. Near the close of the following day for a post-market-EA
  2. Sell-to-close after 7-10 days, or possibly earlier if a desired price target is reached

Similarly,

  1. short a stock one day post-EA if a stock reacts negatively post-earnings:
    1. near the close of trading the EA-day for a premarket-EA
    2. near the close of the following day for a post-market-EA
  2. then buy-to-close after 7-10 days, or possibly earlier if a desired price target is reached

Important: Ride-the-Wave is predicated on significant price momentum triggered by an EA. The 7-10 day scenario is the maximum trade hold-time. If you see post EA-momentum is halted or reversed by a significant opposite move, re-evaluate your presence in the trade.

This popular StockEarnings screen below will give you a list of stocks that historically exhibit significant price momentum following an EA for the next seven days:

  1. Stocks exhibiting positive post-EA price moves are buy-candidates

Volatility Crush Strategy - Best for Options Traders

The Volatility Crush strategy is used with stocks that typically experience relatively low-to-moderate price moves (≤4%) following their Earnings Announcements (EA). The basic trade idea is to sell put or call options right before the EA, collecting a credit when options premium is very high due to elevated implied volatility (IV). You then close the position right after the EA by buying the option back much cheaper due to the significant drop in IV that occurs after the mystery of the EA disappears. In assessing this trade, you need to do your homework to ensure you collect sufficient premium to make the trade worthwhile.

This trade is practical due to the low-to-moderate price-move after the EA, which generally won’t significantly affect the options price, unlike an “action” stock, which experience great price moves post-EA. With these symbols, if you’re on the right side of the price move, that’s a great thing. But if you’re on the wrong side of the move, not so great. Consequently, by minimizing the effect of the post-EA price move, you have a much better chance to profit from the reduction in IV without it being ruined by a violent price move.

For this trade, open the position either (1) the night before the EA when the company announces earnings or (2) during the EA day when it announces post-market, generally capturing IV at or close to its peak.

This popular stockearnings screen will give you a list of stocks which do not react more than 4% fpost-EA. It includes only those stocks whose earnings are releasing next day.

Screen criteria:

  1. Earnings Date Start Date : Current Date + 1
  2. Earnings Date End Date : Current Date + 1
  3. Predicted Move (Next Day) Max : 4%
  4. Options Type: Weekly

Strategy Guideline:

  1. Options Strategy: Sell Call and Put
  2. Options Strike Price: Current Stock Price – (% Predicated Move x 2)
  3. Expiration Date: It should generally be the closest expiry immediately after the EA.
  4. Buy Insurance: Buying back Call and Put at Strike price which 10% lower than Sell Strike Price is optional but recommended.

Volatility Rush Strategy - Best for Options Traders

The Volatility Rush takes advantage of increasing options premiums into earnings announcements (EA) caused by an anticipated rise in Implied Volatility (IV). With this strategy, Buy a Call and Put at-the-money (a long straddle) 2-3 weeks before the EA when IV is lower. Sell the position either (1) the night before the EA when the company announces earnings pre-market, or (2) during the EA day when it announces post-market, generally capturing IV at or close to its peak.

This popular screen will give you a list of stocks whose Options premiums tend to rise into Earnings. It includes only those stocks whose Earnings are at least two weeks away from today.

Screen criteria:

  1. Earnings Date Start Date : Current Date + 15 Days
  2. Earnings Date End Date : Current Date + 30 Days
  3. Predicted Move (Next Day) Min : 5%
  4. Options Type: Weekly or Monthly if that lines up with the two to three-week lead-time for entering the trade

Strategy Guideline:

  1. Buy a Straddle at or close to the money two to three weeks pre-EA.
  2. Sell the position either the night before the EA when the company announces earnings pre-market, or during the EA day when it announces post-market.
  3. Expiration date should generally be the closest expiry immediately after the EA.
  4. Straddle price should not be more 60% of predicted move.

Predicted Move (Volatility)

Similar to Implied Volatility in Options. Expected volatility % based on our Proprietary Volatility Predication Model. We are expecting that stock price will likely to reach % in either direction by the end of next trading session after Earnings are released and not necessarily the closing volatility %.

Why is it important?

    This indicator helps

  1. Knowing expected volatility in stocks after Earnings helps to decide trading stocks before Earnings Announcement.
  2. Taking Advantage of volatility collapse following Earnings Results by using Advance Options strategies such as Spread and Straddles.

Since Last Earnings

Change in share price since last Earnings release.

Why is it Important?

When share has gained more than 10% since it's last Earning release, it tends to over react to minor bad news and give up some gains if not all. So, it contains more downside volatility than upside When share has dropped more than 10% since it's last Earning release, it tends to over react to minor good news and recover some drops if not all. So, it contains more upside volatility than downside.

EPS Surprise (%)

Occurs when a company's reported quarterly or annual profits are above or below analysts' expectations. Here is the formula to derive % EPS Surprice:

Actual EPS - Estimated EPS
------------------------------------- x 100
Estimated EPS

Why is it Important?

Earnings surprises can have a huge impact on a company's stock price. Several studies suggest that positive earnings surprises not only lead to an immediate hike in a stock's price, but also to a gradual increase over time. Hence, it's not surprising that some companies are known for routinely beating earning projections. A negative earnings surprise will usually result in a decline in share price.

Next Day Price Change (%)

Next Regular trading session Closing price following Earnings result.

For After Market Close Earnings, It is a next trading day closing price. For Before Market Open Earnings, It is the same trading day closing price.

Why is it Important?

Next Day price change is a reaction of Earnings result.

This is why Citi Analysts Believe Sandisk Could Rally Another 50%

Posted on May 22, 2026 by Ian Cooper

This is why Citi Analysts Believe Sandisk Could Rally Another 50%

Shares of Sandisk (NASDAQ: SNDK) have already surged more than 3,000%, but some analysts believe the stock still has significant room to climb. In fact, analysts at Citi believe the stock could rally another 50% to as high as $2,025 per share. All thanks to the rising demand for NAND (NOT AND) memory, favorable pricing conditions, and continued growth in artificial intelligence infrastructure.

After all, NAND flash memory is a critical component used in data centers, cloud computing systems, smartphones, and AI applications. As artificial intelligence expands rapidly, demand for high-performance storage solutions is increasing at an equally fast pace. 

And Sandisk, a pure-play NAND stock, is positioned to benefit from it all. According to Citi analyst Asiya Merchant, the supply-and-demand environment for NAND remains highly favorable and could stay strong through the end of the decade.

Sandisk’s long-term customer agreements are also expected to support exceptionally high profit margins, potentially exceeding 80% in future years. These contracts provide the company with stronger revenue visibility while helping shield it from short-term market fluctuations.

“Raising SNDK [target price] to $2,025 (9-10x CY27E PE) from $1,300 (7-8x prior) following strong Kioxia earnings, reinforcing our view of persistently strong storage demand and a highly favorable pricing environment, fueled by intensifying AI interest,” analyst Asiya Merchant wrote in a note to clients, as quoted by Seeking Alpha.

NAND Supply Cannot Keep up with Demand



A major catalyst for the explosive NAND demand is artificial intelligence data centers. AI systems require enormous amounts of data processing and storage capacity, which directly increases the need for NAND memory. Every new AI server, cloud platform, and large-scale data center expansion creates additional demand for advanced storage products.

At the same time, NAND supply growth has not been able to keep pace with this surge in demand. Manufacturing capacity was not originally designed to support the massive expansion now taking place in AI computing. Building new semiconductor fabrication facilities takes years and requires billions of dollars in investment. As a result, supply remains relatively constrained while demand continues to accelerate.

The rapid growth of data centers further supports the long-term outlook. 

There are currently around 4,000 operational data centers in the United States, with another 1,500 to 3,000 either planned or under construction. Research also shows strong regional expansion across the country, particularly in the South and Midwest. Globally, there are now more than 10,000 data centers, and nearly all require large amounts of NAND storage to operate efficiently. As AI adoption spreads worldwide, the need for advanced memory solutions is expected to grow substantially.

Sandisk Earnings Have Been Strong

The company recently reported earnings per share of $23.41, beating analyst expectations by $8.75. Revenue reached $5.95 billion, which was year-over-year growth of more than 252%. That also beat estimates by $1.22 billion. 

CEO David Goeckeler highlighted the company’s financial strength in the latest earnings release, pointing to its zero-debt balance sheet, strong cash generation, and recently authorized share repurchase program. 

Looking ahead, SanDisk expects fourth-quarter revenue to range between $7.75 billion and $8.25 billion, with diluted net income projected between $30 billion and $33 billion. Management also believes results could improve further as AI-driven demand for NAND storage continues to rise.

Overall, the company appears well-positioned for continued growth. Strong earnings, expanding margins, aggressive analyst price targets, and ongoing AI infrastructure investment all support the bullish case for the stock. While shares have already delivered enormous gains, many investors and analysts believe the long-term opportunity in AI and data center expansion could still drive meaningful upside for SanDisk in the years ahead.

Investors should also recognize that NAND memory remains one of the foundational technologies behind the broader AI boom. While many AI stocks focus on chips or software, storage demand is becoming equally important as data volumes explode. If current supply constraints persist, Sandisk could continue benefiting from stronger pricing power and expanding profitability for years.
