SanDisk, SpaceX, Nike, Pinterest: Down 50% to 76%. Value Opportunities or Falling Knives?

Four famous stocks have lost between 43% and 76% from their respective all-time highs. That sounds like a clearance sale. It is not. SanDisk, SpaceX, Nike and Pinterest have fallen for very different reasons, and only one question matters now: has the price fallen further than the underlying value, or is the market still correcting an earlier excess?

Let's break down what the current prices actually imply, how much each stock could rise if it revisits its peak, what financial repair would make that possible, and the price or earnings level at which the risk-reward starts looking more sensible.

Four Big Declines, but Four Very Different Starting Points

The table below uses the August 5, 2026 regular-market close and each stock's highest intraday price. SanDisk's results were released after the close, and its shares later traded near $1,244 in after-hours activity. At that level, its decline from the peak widened to about 47%, but the common closing-price snapshot keeps the four-stock comparison consistent.

There is an important piece of maths hiding here. A 75% fall is not reversed by a 75% rise. If a ₹100 stock falls to ₹25, it must climb 300% to return to ₹100. Falling into a deep pit is easier than climbing out of it.

That is why Nike and Pinterest do not merely need a recovery. They need a multi-fold increase. SanDisk, despite the eye-catching fall, has the shortest mathematical route back to its high. SpaceX would need to more than double.

The Three-Discount Test: How to Separate Value From a Trap

Comparing these businesses directly would make little sense. One makes flash memory, one combines rockets, satellite internet and AI infrastructure, one sells sportswear, and one runs a visual discovery and advertising platform. We are not comparing their businesses. We are comparing the quality of the discount in their stocks.

For that, this article uses a simple three-part framework.

1. The price discount: How far is the stock from its peak?

This is the number everyone sees. It is useful, but incomplete. An all-time high may have been set when profit margins, growth expectations or valuation multiples were unusually high.

2. The earnings discount: What multiple are investors paying on sustainable earnings or cash flow?

The word sustainable matters. SanDisk's current profit is being helped by extraordinary NAND pricing. SpaceX is spending far more cash than it generates. Nike's brand remains powerful, but its growth has stalled. Pinterest's reported free cash flow looks attractive, but stock-based compensation weakens its quality.

3. The repair discount: What must the company achieve to make its old peak financially reasonable again?

This is the missing question in most drawdown articles. A stock is not attractive merely because it once traded at a higher price. The old price must be supported by future revenue, earnings and cash flow.

Think of the all-time high as an old rent agreement. The fact that a previous tenant paid an inflated amount does not mean the next tenant should. The property must still justify the rent.

SanDisk Valuation: Cheap Earnings or Peak-Cycle Illusion?

SanDisk is the most difficult stock here because its current valuation looks extremely low and extremely risky at the same time.

In fiscal Q4 2026, revenue rose 372% year on year to $8.97 billion. Non-GAAP EPS reached $39.25, while gross margin hit 84.6%. For Q1 FY2027, management guided to $10.3-$10.8 billion of revenue, an 83%-85% non-GAAP gross margin and $44-$46 of non-GAAP EPS. Datacentre revenue more than doubled sequentially to nearly $3 billion. These are exceptional numbers. 

SanDisk's official results also showed that roughly two-thirds of sequential revenue growth came from higher pricing and one-third from higher volume.

That last detail is the heart of the risk. When most growth comes from higher memory prices, current earnings can be real without being permanent.

What Does SanDisk's Current Price Assume?

The midpoint of Q1 EPS guidance is $45. Annualising one quarter is not a forecast, but it gives a useful stress-test earnings figure of $180.

On near-term earnings, SanDisk looks inexpensive even at the old peak. On normalised earnings, the conclusion changes completely.

The comparison is like a hotel charging five times its normal room rate during the cricket World Cup. The revenue is genuine, but valuing the hotel as if every week will be World Cup week would be dangerous. SanDisk's 84.6% gross margin is the World Cup week in this analogy. Fiscal 2025 non-GAAP gross margin was only 30.3%.

What Must SanDisk Achieve to Reclaim Its ATH?

At $2,354.39, SanDisk's market value would be about $349 billion at the current share count. The stock could justify that level with:

• Roughly $157 EPS at a 15x multiple
• Roughly $196 EPS at a 12x multiple
• Roughly $235 EPS at a 10x multiple

The Q1 guidance annualises to about $180, so the peak is not mathematically absurd. The problem is duration. Investors need evidence that datacentre demand, customer agreements and disciplined industry supply can keep annual EPS well above $150 after NAND pricing normalises.

Our Read on SanDisk

At around $1,350, SanDisk is not obviously expensive. It is simply difficult to underwrite because one unusually profitable quarter changes the valuation so sharply.

The level that improves the setup for me is around $950-$1,050. At $1,000, even $100 of normalised EPS would mean a 10x multiple. The alternative proof point is more important than any chart level: evidence that annual EPS of roughly $110-$120 can survive a meaningful decline in NAND pricing.

Until one of those conditions appears, SanDisk is a cheap-looking cyclical stock with unusually high peak-margin risk. Near $1,000, that same risk becomes easier to accept because the price leaves more room for earnings normalisation.

SpaceX Valuation: Innovation Is Real, but So Is the Price

SpaceX is the easiest company here to admire and the hardest one to value conventionally.

The company listed in June 2026 at $135 and briefly touched $225.64. Its first public earnings report showed Q2 revenue of $7.81 billion, up 92% year on year, adjusted EBITDA of about $3.5 billion and a net loss of $541 million. The shock was capital expenditure of $18.37 billion, about 2.35 times quarterly revenue. The stock closed at $108.27 on August 5. 

SpaceX also ended the period with roughly $100 billion of cash after its IPO and bond raise, which gives it capacity to fund the buildout. Capacity, however, is not the same as return on capital.

The Valuation at $108 and at $80

S&P Global consensus data points to about $39.1 billion of revenue in 2026 and $73.2 billion in 2027. Those estimates will move, but they let us test the current market value.

Even at $80, SpaceX would not look conventionally inexpensive. The attraction at that level would come from optionality: Starlink, reusable launch economics, government contracts, Starship, AI compute and technologies that may not fit neatly into today's spreadsheet.

Optionality means the possibility of creating value from outcomes that are difficult to forecast today. It is like paying for a large plot of land because it could eventually support several profitable buildings. The risk is that investors pay for all the buildings before construction has proved they can earn an adequate return.

What Must SpaceX Achieve to Reclaim Its ATH?

At the old peak, SpaceX would again be worth almost $3 trillion. To support that value:

• At 15x sales, annual revenue would need to approach $198 billion
• At 10x sales, annual revenue would need to approach $297 billion
• Free cash flow would need a credible path from deeply negative to strongly positive

For context, S&P Global's 2027 revenue estimate is about $73 billion. Elon Musk has spoken of $1 trillion in annual revenue by 2030, while a Barron's report cited a much lower Wall Street estimate of roughly $448 billion for 2030. The gap tells us how wide the outcome range is.

Our Read on SpaceX

SpaceX is not a normal value case. It is an execution-and-optionality case.

Around $75-$85, I would strongly consider it for a small, explicitly high-risk part of a portfolio. That view is not based on current free cash flow. It is based on SpaceX's innovation record, the number of large markets it is attacking and Elon Musk's history of turning previously improbable engineering goals into operating businesses.

At $108, I would want more proof. An equally acceptable trigger would be a 2027 revenue run rate above roughly $90-$95 billion, capex falling closer to revenue instead of standing at more than two times revenue, and a visible route to positive free cash flow. Without that, the story remains extraordinary but the valuation still asks investors to pay well ahead of proof.

Nike Valuation: A Great Brand Is Not the Same as a Cheap Stock

Nike has the largest percentage decline in the group, but it is not the lowest-valued stock on earnings.

For FY2026, Nike reported $46.4 billion of revenue, broadly flat year on year and down 2% on a currency-neutral basis. Nike Direct revenue fell 6%, Nike Brand Digital fell 12%, Converse revenue fell 31%, and Greater China remained weak. Wholesale revenue, however, grew 6%, showing that the effort to repair retail partnerships is producing some progress. Full-year diluted EPS was $2.10.

At $42.45, Nike trades at about 20.2x reported trailing earnings, 24.8x forecast FY2027 adjusted earnings and 28.8x trailing free cash flow. Its dividend yield is close to 3.9%. These are lower multiples than investors once paid, but they are not distressed valuations for a company whose revenue is not yet growing.

What Would Make Nike's Current Price More Attractive?

Sources: Nike financial and valuation data and S&P Global forecasts. Internal Calculations.

Nike's brand is an asset, but the stock needs the brand to produce growth again. The most useful indicators are not social-media buzz or one popular shoe. They are full-price sales, digital revenue stabilisation, wholesale growth without heavy discounting, Greater China improvement and gross-margin recovery excluding unusual tariff effects.

What Must Nike Achieve to Reclaim Its ATH?

At $179.10, Nike's market value would be roughly $265 billion. A more sustainable route to that price would require:

• EPS of about $6 at a 30x multiple, or $7.16 at a 25x multiple
• Net income of roughly $8.8-$10.6 billion, versus $3.1 billion in FY2026
• Revenue of roughly $59-$71 billion if net margin reaches 15%
• Revenue of roughly $74-$88 billion if net margin remains closer to 12%

In plain language, Nike probably needs to triple current profit or persuade the market to award it another unusually high multiple. Reclaiming the peak is therefore much harder than the famous logo makes it appear.

Our Read on Nike

Nike is the only stock in this group where I am willing to consider a small, staged turnaround allocation at the current price. The thesis is not that a 76% fall makes it automatically inexpensive. The thesis is that a globally dominant brand, a repairing wholesale channel, nearly $9 billion of cash and a 3.9% dividend yield provide some support while management attempts the turnaround.

This remains a risk-led decision, not a clean valuation case. Greater conviction would come below roughly $35, or at the current price after EPS recovers beyond $2.50 with Nike Direct and Greater China no longer contracting sharply. The brand creates the opportunity. Only operating improvement can validate it.

Pinterest Valuation: The Free-Cash-Flow Bargain With an Asterisk

Pinterest may be the most interesting accounting puzzle in the group.

Q2 2026 revenue rose 18% to $1.18 billion, monthly active users reached a record 640 million, adjusted EBITDA increased 24% to $311 million and reported free cash flow reached $270 million. The company also completed more than $2 billion of repurchases in the first half at an average price of $18.17.

At $23.36, Pinterest is valued at about 2.9x trailing sales and 10.3x reported free cash flow. Based on the $1.90 FY2026 adjusted EPS consensus, the multiple is about 12.3x. On those numbers, it looks like the clearest value candidate here.

Then comes the asterisk.

Pinterest recorded roughly $325 million of stock-based compensation in Q2, equal to about 28% of revenue and higher than the quarter's $270 million of free cash flow. Stock-based compensation is pay given in company shares. Cash does not leave the bank, so it is added back in the cash-flow statement, but existing owners are giving employees pieces of the same company pie.

A conservative owner-earnings check is:

Reported free cash flow - stock-based compensation

For Pinterest in Q2, that rough calculation is:

$270 million - $325 million = approximately -$55 million

This is not a formal accounting measure, and repurchases can offset dilution. It is still a useful warning that the 10.3x free-cash-flow multiple overstates the cash economically available to owners.

What Would Improve Pinterest's Risk-Reward?

Sources: Pinterest valuation data and S&P Global forecasts. Internal Calculations.

The $18-$20 range is interesting because it is close to the company's $18.17 average repurchase price and provides more protection against slower advertising growth. The other path is proof rather than a lower price: quarterly stock-based compensation below 20% of revenue, a GAAP operating margin above 10%, and revenue growth remaining near or above 15%.

What Must Pinterest Achieve to Reclaim Its ATH?

At $89.90, Pinterest would be worth about $51 billion at the current share count. To support that value:

• At 5x sales, revenue would need to reach about $10.2 billion
• At 4x sales, revenue would need to reach about $12.7 billion
• At 25x earnings, EPS would need to reach about $3.60
• At 25x free cash flow, sustainable annual free cash flow would need to exceed $2 billion

Current trailing revenue is about $4.6 billion. At a 13%-15% growth rate, reaching $10 billion could take roughly six to seven years. That makes Pinterest's old peak a long-duration operating target, not a quick rebound target.

Our Read on Pinterest

Pinterest is more attractive than its 74% fall alone suggests, but less attractive than the headline free-cash-flow multiple suggests.

I would become meaningfully interested around $18-$20. At the current price, I would want to see the quality of earnings improve first. Specifically, stock-based compensation must grow materially slower than revenue, GAAP profit must become consistent, and international user growth must convert into better revenue per user.

Pinterest does not need explosive growth to work from a $13 billion market value. It needs cleaner ownership economics.

Which Stock Has the Best Risk-Reward Today?

The strongest current story and the strongest current valuation are not the same thing. SpaceX has the strongest story. SanDisk has the lowest near-term earnings multiple. Nike has the strongest established consumer brand. Pinterest has the most intriguing reported cash-flow valuation.

My ranking is therefore conditional:

1. Nike at current levels: The only one I would begin to risk-budget now, and only in a small, staged manner.
2. SanDisk near $1,000: The most compelling price-led setup if normalised EPS remains near $100 or better.
3. Pinterest near $18-$20: An attractive cash-generating platform only after adjusting for share compensation.
4. SpaceX near $80: The highest-risk and potentially highest-optionality setup, but still expensive on ordinary metrics.

This ranking is about the quality of today's risk-reward, not the quality of the four businesses.

Author's Note: Why I Am Tracking These Four Stocks

I am tracking these companies because each represents a different version of the same investor temptation.

SanDisk tests whether apparently low earnings multiples can be trusted at the top of a cycle. 

SpaceX tests how much one should pay for innovation that may create entirely new markets. 

Nike tests whether a world-class brand can repair weak execution. 

Pinterest tests whether reported cash flow is truly reaching owners.

My preferred SanDisk level is around $1,000 because it gives enough room for NAND margins to normalise. SpaceX becomes worth serious consideration near $80 for the high-risk part of a portfolio, mainly because of the company's innovation record and Musk's history of delivering outcomes once viewed as unrealistic. Nike is the one where I am prepared to take a limited risk around current levels, but the exposure should increase only as operating proof arrives. Pinterest starts to make more sense around $18-$20, or earlier if stock-based compensation drops below 20% of revenue and GAAP profitability becomes durable.

The key is not to predict the exact bottom. It is to demand enough price cushion or enough business proof that being slightly early does not destroy the thesis.

The Bottom Line

A stock falling 50% or 75% tells us where it has been, not what it is worth.

SanDisk offers the shortest financial bridge back to its peak, but also the greatest peak-margin risk. SpaceX offers unmatched optionality, but its current valuation still assumes extraordinary execution. Nike's brand supports a turnaround thesis, yet the stock requires real earnings repair. Pinterest looks inexpensive on reported free cash flow, but heavy share compensation makes the underlying economics less attractive than the headline multiple.

None of these four is a clean bargain purely because it has fallen. Nike is the most defensible limited risk at today's price. SanDisk becomes more compelling near $1,000. Pinterest needs either $18-$20 or cleaner owner earnings. SpaceX needs roughly $80 or much stronger proof that its enormous capital spending will produce durable free cash flow.

That is the difference between catching a falling knife and finding value: not the size of the fall, but the amount of future business performance already embedded in the price.
