A 60-Year-Old Who Bought 1,000 Micron Shares at $192 Just Lost $138,840. He’s Still Up $464,000. Here’s What Happens Next.

Micron Technology (NASDAQ: MU) lost $138.84 a share on Thursday. The stock closed at $656.39, down 17.5% in one session, in a year that had been the best in the company’s history. Since Oct. 1, when it closed at $1,097.39, Micron has lost 40% of its value.

Put a person on those numbers. A 60-year-old investor who bought 1,000 shares a year ago near the 52-week low of $192.37 put in about $192,000. At Wednesday’s close that stake was worth $795,230. On Thursday night it was worth $656,390. He lost $138,840 in one day, and he is still up $464,000. An investor who bought the same 1,000 shares on Oct. 1 is down $441,000.

Both of them are asking the same thing tonight, and the answer runs through a construction site in Taiwan.

What happened on Thursday

Three things hit the stock at once. Chip stocks were already falling for a second day on fears that the new Congress and several states will slow data center construction. Nvidia fell 9.3% and Western Digital fell 17.4%. SanDisk, Micron’s closest peer, fell 22.3%. Then Qualcomm, the largest maker of phone chips, gave a weak profit forecast and said higher component costs are weighing on its business, a sign that Micron’s customers are starting to push back on what memory costs.

The third piece was Micron’s own. Bloomberg reported that the company has all but halted work on a new memory plant in Taoyuan, Taiwan, a project budgeted at $3 billion to $4.5 billion and due to open in 2028. The reason is a pay dispute.

The $15 billion demand

Micron signed a deal with its larger Taiwan union on Oct. 21 that, according to Taiwan’s economy ministry, more than doubles a junior engineer’s average annual package to about $121,000. A smaller union in Taoyuan, which represents fewer than 3,000 of Micron’s 15,000 workers on the island, wants that deal thrown out. Its demand is a formula: 15% of Micron’s operating profit, shared with employees worldwide and paid in cash. Samsung and SK Hynix have adopted similar plans, and the union cites them.

Run the formula against Micron’s own results. In the fiscal year that ended in August, Micron reported $133.2 billion of revenue and $99.3 billion of operating income, up from $9.9 billion the year before. Fifteen percent of $99.3 billion is $14.9 billion a year. The plant Micron stopped building costs $4.5 billion at most, once.

That is why the company froze a plant instead of paying. A halted building site costs it nothing this year, because the plant was two years from making a chip. A profit formula would take $14.9 billion out of operating income every year the boom lasts, and it would not stay in Taiwan. Workers in Idaho, Japan and Singapore read the same earnings releases.

The three numbers that decide what happens next

The first is 60%. That is the share of Micron’s DRAM made in Taiwan, according to Bloomberg. A paused plant does not touch this year’s output. A strike would. Micron told Bloomberg it is “confident in maintaining business continuity for our customers,” and the economy ministry has backed the October agreement. If the Taoyuan union wins enough members to reopen it, the risk moves from a future plant to current production.

The second is 80.7%. That is Micron’s operating margin over the past year, far above anything the memory business has sustained before. The stock’s price says investors do not believe it will last: at $656.39 Micron trades at 8.8 times the $74.33 a share it earned over the past year and between 4 and 5 times what analysts expect it to earn next year. A 15% profit share would cut that margin by 12 points on its own.

The third is $1,562. That is the average price target among the analysts who cover the stock, 45 of whom rate it a buy against 3 holds and 1 sell. The target implies the stock more than doubles. Targets like that were set before this week, and the first test of them is Micron’s next earnings report in December.

What to do if you own it

If you are the investor who bought at $192, Thursday cost you $138,840 and left you with a gain of $464,000. Your question is taxes and concentration, not Micron’s wage bill. Selling a third of the position locks in about $155,000 of gain, taxed at long-term rates once you have held for more than a year, and leaves 667 shares to ride.

If you bought in October above $1,000, the loss is real and the tax code will share it with you. A sale now creates a loss you can use against other gains this year, and you can buy back after 31 days if you still want the stock.

If you are thinking about buying, the price already assumes the boom ends. What it does not assume is a strike at the plants that make 60% of the company’s DRAM. Watch the Taoyuan union’s membership drive and Micron’s December report. Those two will tell you more than Thursday’s price did.

Micron pays a dividend of 15 cents a quarter, a yield of about 0.1%. Nobody owns this stock for the check. They own it for the margin, and the fight in Taiwan is over who gets to keep it.
