Micron’s $54.23 Billion Quarter Meets a $650 Support Test

By Nathan Brooks

Micron Technology reported $54.23 billion in fiscal fourth-quarter revenue, up 379%, before its shares fell 17.46% on November 5, 2026. Revenue and the share price pointed in opposite directions.

Micron closed at $690.00 on November 6, gaining 5.12% after the rout, yet remained approximately 29.8% below its October 28 close of $983.23. The November 5 low of $650.00 and close of $656.39 were the lowest of the previous 50 sessions, while trading volume reached roughly 77.9 million shares, nearly 2.9 times the 30-session average.

What did Micron actually report?

Micron’s September 30 results put three figures on the board:

• Fiscal fourth-quarter revenue of $54.23 billion, up 379% from $11.32 billion a year earlier.
• GAAP net income of $37.70 billion, or $32.87 per diluted share.
• Full-year revenue of $133.19 billion, representing 256% annual growth.

For fiscal first-quarter 2027, the company guided revenue to $61.5 billion, plus or minus $1.5 billion, against analyst expectations near $56.8 billion. Management expects non-GAAP gross margin around 86.25% and non-GAAP EPS of approximately $38.15.

Micron management expects “sequential revenue growth throughout fiscal 2027,” supported by strong demand for memory products. Quarterly DRAM revenue reached $39.8 billion, while NAND revenue reached $14.1 billion.

What happened to the Taiwan fab?

A November 5 report said Micron had suspended plans for a $4.5 billion memory-chip facility in northern Taiwan following a labor dispute. The project had targeted DRAM and high-bandwidth memory production.

The report arrived during an already volatile period for semiconductor stocks. It added operational uncertainty to Micron’s expansion plans, rather than providing a clear explanation for the scale of the November 5 selloff.

Why did shares fall?

Micron’s weakness started before its largest one-day drop. From its October 28 close of $983.23, the stock fell 4.98% on October 29 and another 5.30% on October 30, while investors reassessed expectations for AI infrastructure spending in early November.

On November 5, MU opened at $752.69, reached $761.81 and fell to $650.00 before closing at $656.39, down 17.46%. Trading volume of roughly 77.9 million shares was the highest of the previous 50 sessions.

The Philadelphia Semiconductor Index fell more than 12%, and the Nasdaq Composite declined 5.52%, entering correction territory. Concerns about future data-center construction and the reported Taiwan suspension fed the negative sentiment.

Technology stocks recovered on November 6, and Micron initially rebounded with them. Shares opened at $708.35, reached $724.80 and finished at $690.00, up 5.12%. They closed below the opening price and near the bottom of the daily range, suggesting that much of the early buying interest had faded.

What do the technical levels show?

The market now has a compact set of reference points:

• $650.00: The main downside reference and the November 5 low.
• $676.00: The November 6 session low, offering a nearer marker for renewed selling pressure.
• $724.80 and $761.81: Initial resistance, drawn from the November 6 high and the November 5 high.
• $795.23: The November 4 closing price and the next higher resistance level.

Micron’s 20-day simple moving average sat near $879.01, and its 50-day average was near $961.64. The November 6 close remained 21.50% and 28.25% below those averages, respectively, and approximately 43.12% below its June 25 record close near $1,213. Substantial earlier gains remain part of the record, but the rebound has not restored upward momentum.

Thursday’s $650.00-to-$761.81 trading range covered about 17% of the closing price, nearly four times the 50-session average range of 4.4%. Friday’s range narrowed to about 7.1%, yet the stock closed at only 28.7% of that range after opening 7.92% higher. Sellers remained active during the rebound.

Holding above $650 would preserve the possibility of stabilization. A sustained recovery through $724.80 and $761.81 would offer stronger evidence that selling pressure was easing.

Is this a valuation reset or a cycle warning?

The bull case rests on the 379% revenue increase, the $61.5 billion quarterly guide and a lower valuation after the selloff. Micron’s trailing price-to-earnings ratio has fallen to near 9.3, while forward multiples fell below 4 on several measures. Analysts maintain a “Strong Buy” consensus. If MU holds $650 and reclaims $724.80, the technical case points to recovery toward $761.81 and $795.23.

The bear case focuses on the memory cycle. Micron’s profitability remains sensitive to prices that can change rapidly as supply and demand shift. AI infrastructure spending, the reported Taiwan suspension and the stock’s position below its major averages leave room for a correction that is not finished. The fading rebound has not given buyers control.

Micron still faces sector, volatility and earnings-cycle risk, including the November 5 selloff’s sensitivity to broader semiconductor sentiment. The reported Taiwan disruption adds operational uncertainty, and Thursday’s 17% range demonstrated how quickly the stock can move.

Technical levels describe historical price behavior, not guaranteed outcomes. Trading Micron carries a risk of losing invested capital.

Micron can defend $650 and recover toward $725-$762, or the rebound can prove temporary. The next test is whether memory pricing supports the projected sequential revenue growth despite cycle fears, AI infrastructure doubts and uncertainty from the reported Taiwan project suspension.
