You Don't Find a 10-Bagger, You Survive One: What Micron's 20x Actually Taught Me

The Memory Company Nobody Wanted

For most of its life, Micron was the kind of stock investors went out of their way to ignore.

It makes memory chips, the storage that sits inside computers, phones, and data centers. That business is famously up and down, what we usually call cyclical. When conditions turn bad, memory prices collapse, Micron's profit vanishes, and the stock gets crushed. Near the lows, this name attracted three labels: boring, cyclical, dead money.

Then everything flipped.

The AI boom created a desperate hunger for memory, the exact product Micron makes. Supply ran short. Prices exploded, profits exploded, and the stock went vertical. From its beaten-down lows, it climbed as much as 20 times in just a few years. That is 10,000 dollars turning into 200,000.

That part is just a pleasant story. What I actually want to talk about is what came next.

The People Who Made That Money Were Not Watching the News

Nobody captured that 20x by buying Micron when it was on the news every night.

The ones who did well bought it when it was hated, when it was boring, when it was cheap, and then they held. I know an investor whose cost basis was 66 dollars. What made that price special was not a flash of insight, it was the willingness to own something the entire market had written off.

And this was not a one-in-a-million lightning strike. Look at the last few years alone:

• Meta: November 2022, down more than 70 percent from its high, with the world convinced Mark Zuckerberg had lost his mind. Shares are up close to seven times from those lows.
• Google: Held through the stretch when everyone swore AI chatbots would kill search. That is close to a five-bagger.
• Intel: Bought when it was beaten down and forgotten, and it has crushed it since.
• Sprouts Farmers Market: From the 20-dollar range to as high as 180. Even after falling 50 percent from there, it is still a 4x.

What do these have in common? Not better information. The people who won knew what they owned, had done the work to estimate what it was worth, and kept their hands off the keyboard while everyone around them panicked.

Multibaggers Are Not Hard to Find. They Are Hard to Hold.

Here is the claim I want to make as directly as I can: finding a 10-bagger is the easy half. Holding one is where almost everyone loses.

Think about what a 10x or 20x actually requires. It requires sitting through drops that make you physically uncomfortable. I cannot think of a single stock that went straight up. It goes up, but with violent swings along the way. Micron's climb was not a smooth line. It had stomach-dropping plunges the entire way, and that is normal.

Almost every huge winner in history fell 50 percent or more at some point, often multiple times. Amazon once fell more than 95 percent and still became one of the greatest returns in market history. Charlie Munger and Warren Buffett regularly point out that Berkshire Hathaway has fallen over 50 percent several times during their tenure. And the uncomfortable truth buried in that: those were the moments when the opportunity was best.

So be honest with yourself. When the thing you own gets cut in half, are you actually the person who holds? I am not always confident I am.

The Second Trap Is More Common: Selling the Winner Too Early

Selling in a crash is not even the most frequent mistake. Selling into strength is.

You buy a great company, it doubles, and locking in the gain feels enormously smart. I used to repeat the line that you can't go broke taking a profit. I no longer believe it, because it is not technically true. When you lock in that gain, you often forfeit a far larger number sitting further out on the curve.

So you sell. And you watch it climb another five times without you.

What makes this mistake so expensive is that it is disguised as a win. The account shows green, you feel warm and clever, and there is no invoice that teaches you what it cost. Selling a wonderful, still-growing business purely because the price went up is one of the most expensive habits in investing, and it is the one people are proudest of.

There is an old saying I keep coming back to: you don't find a 10-bagger, you survive one. The hard part is never the buy button. It is keeping your hands still while the compounding does its slow work.

The Instant-Gratification Paradox

We live in a society built on instant gratification. The idea of waiting years, sometimes a decade, to see the real gain is physically difficult for most people. But that difficulty is exactly why the opportunity still exists. If everyone could do it, the excess return would already be gone.

My conclusion is practical. Spend half the time you currently spend hunting for the next winner on writing down your holding rules instead. Can you state in one sentence what you own and why? Have you actually estimated what it is worth? Have you decided in advance what would make you sell? With those three in place, a 50 percent drawdown stops being an emergency and becomes a scenario you already priced in.

For a more concrete version of this, see my two-scenario fair value analysis of Micron and my notes on buying Intel at 17 dollars.

FAQ

Q: Should I just never sell a big winner? A: No. The reason to hold should be "it is still growing and still reasonably priced," not "it went up a lot." If the business is impaired or the valuation has entered obvious bubble territory, selling is correct. What I argue against is selling for the single reason that the price rose.

Q: What if I know I can't stomach a 50 percent drawdown? A: Cut the position size. Adjusting your allocation is far more realistic than changing your temperament. Size it down to an amount you could see halved and still sleep, and paradoxically you will hold it far longer.

Q: Is it wrong to buy the stock everyone is excited about right now? A: Not wrong, but understand what you are paying for. When the story is already universally known, it is already in the price. What produced Micron's 20x was not AI demand itself, it was the price that existed before the demand arrived. "This is fine to own" and "this will 10x" are completely different statements.
