| Entry Price | Exit Price | Return | |
|---|---|---|---|
| WDC | $47.88 | $310.81 | +549% |
| SNDK | $0 (spinoff) | $768.98 | Zero cost basis |
| Combined | Dec 2023 | Mar 2026 | +1,084% (12x) |
Every dollar invested in this campaign at our published entry returned roughly twelve dollars at exit. The SanDisk shares were received as a spinoff from the Western Digital position at zero cost — pure upside. The combined return of +1,084% represents model portfolio results at published prices. Your actual return depends on your sizing and execution.
In May 2023, Paul Singer's Elliott Management took a billion-dollar position in Western Digital and penned a letter to the board calling for the separation of the company's flash memory business from its hard drive business. They called it one of the most attractive risk-return profiles they had ever seen — a significant statement from a fund with a nearly 50-year track record and only two losing years.
The math was simple and devastating. Western Digital had acquired SanDisk in 2016 for 3x revenue. But by 2023, the market was valuing the combined Flash business within Western Digital at just 0.3x revenue — roughly $6 billion. Comparable Flash businesses traded at 3x, implying the Flash business alone was worth $15 to $20 billion more than the market was giving credit for. The value was there. It was just trapped inside the conglomerate.
Elliott followed their initial billion-dollar stake with another $900 million in preferred stock, in collaboration with Apollo Global. The preferred converted at $47.75 — almost exactly where we entered.
We entered Western Digital on December 8, 2023, at $47.88 per share. This was 17 months into Elliott's campaign, and the wheels were already in motion. The company had announced the plan to spin off the Flash business (SanDisk) in late October 2023. The catalyst was not speculative — it was in process.
We entered right at the level where Elliott's $900 million in preferred stock converts to equity. That alignment mattered. Singer and his team — who had built a near-50-year track record returning 14% annually after fees with only two losing years — had nearly $2 billion committed to this thesis. When the best activist fund in the world puts that kind of capital behind a single idea, the signal is clear.
Singer's team had a history of successful campaigns in storage and computing companies — big wins in Dell, EMC, and NetApp. They understood the sector. And they understood that the trillion-dollar retooling of the world's data centers for AI would drive massive demand for both flash storage and hard drives.
SanDisk hit an all-time high of $776 the day before we exited. Western Digital was at $319. The AI storage demand cycle was the strongest in history. Micron had just reported 75% gross margins and guided 81%. So why sell?
Three reasons. First, Elliott had exited. The activist whose thesis we followed — whose $2 billion commitment was the reason we entered — had left the position. The catalyst that brought us in was complete. What remained was a bet on the memory cycle, and that's a different kind of bet.
Second, the scarcity premium was fully priced. SanDisk up 28x from its post-spin lows. That kind of move doesn't leave room for the thesis to "work" — it's already worked. The rest is pricing power embedded in the stock price that depends on supply staying tight indefinitely.
Third, the risks to the scarcity narrative were building on four fronts simultaneously. Micron, SK Hynix, and Samsung were pouring billions into new manufacturing capacity — 18-30 months from shipping but the market prices it in early. Nvidia was engineering around the storage bottleneck with new architectures at GTC. AI was being applied to the manufacturing process itself, potentially accelerating capacity faster than historical norms. And new memory architectures were emerging that could shift demand away from traditional NAND and HDD.
Even if the stocks ran another 20% from there, a single negative headline on any of those four fronts could evaporate that gain in a single session. The move down is always faster than the move up, because the scarcity premium unwinds all at once.
We followed the best activist in the world into a deeply undervalued company. We held through the spinoff. We held through the AI explosion. We generated a return that will define this portfolio's track record for years. And we exited when the catalyst was behind us — not because the story was over, but because the risk/reward had shifted.
That discipline is the difference between a 12x winner and a round trip.
The WDC/SNDK campaign is a textbook example of the Billionaire's Portfolio process. Every element was present before we entered. An activist investor with one of the longest-running track records in hedge fund history. A specific, identifiable catalyst (the spinoff) that was already in motion. A valuation gap so wide — 0.3x revenue versus 3x for comparable businesses — that the math was undeniable. And an entry point aligned with the activist's own cost basis.
What we didn't anticipate was the second engine. The AI infrastructure boom turned a 100% spinoff arbitrage into a 1,084% outcome. That's the asymmetry at work. The defined downside was the entry price. The upside was multiples — and when a secular demand shift compounds on top of an activist catalyst, the multiples get very large.
This is how the Billionaire's Portfolio operates across all 48 exited campaigns. Follow the activist with the best track record. Understand the catalyst. Verify the valuation gap. Enter when the hard work is done and the catalyst is in process. Exit when the activist exits or the catalyst is complete. The math works because the winners — campaigns like WDC/SNDK (+1,084%), T-Mobile (+238%), Freeport McMoran (+237%), Cleveland Cliffs (+208%) — more than pay for the campaigns that don't work out.
48 exited campaigns. +61.5% average gain. 69% win rate. 2.9:1 asymmetry — the average winner is nearly three times the size of the average loser. That's the track record. And it starts with finding the next one.
We're looking for the next one. Every entry, every exit, and the reasoning behind each decision — shared in real time.
