Why Is Seagate Stock Falling on Friday?

Seagate Technology Holdings PLC (NASDAQ:STX) stock traded lower on Friday. The downswing stems from a broad market sell-off across global semiconductor and technology hardware stocks. Nasdaq futures are up 0.18% while S&P 500 futures have gained 0.27%.

The sector-wide decline followed disappointing earnings results from prominent technology firms earlier in the week.

The market pressure intensified after overnight crashes in South Korean chipmakers, including SK Hynix Inc (NASDAQ:SKHY).

Strategic Position Trimming

Investors are pulling profits and trimming positions to mitigate risk ahead of Seagate’s upcoming fourth quarter of 2026 earnings report, scheduled for Tuesday.

Analysts estimate earnings per share of $5.04 and quarterly revenue of $3.48 billion.

Wall Street adopted a defensive stance on high-flying artificial intelligence trades following disappointing updates on Thursday from mega-cap technology companies.

Tech Earnings Drag

Among those updates, Alphabet Inc. (NASDAQ:GOOG) (NASDAQ:GOOGL) repurchased no stock in the first quarter or second quarter of 2026 after spending $28.31 billion on buybacks during the comparable 2025 period.

Alphabet increased its 2026 capital expenditures outlook to between $195 billion and $205 billion to support AI infrastructure, which pushed its second quarter free cash flow to negative $5.86 billion.

Management noted on its earnings call that technical-infrastructure investment would continue pressuring free cash flow.

Simultaneously, Tesla Inc. (NASDAQ:TSLA) reported second-quarter adjusted earnings per share of 33 cents, missing the consensus estimate of 50 cents.

Tesla reported revenue of $28.23 billion and deliveries of 480,126 vehicles. Following the report on Thursday morning, Tesla stock fell 7.76% to $344.97.

The combined capital allocation shifts and earnings misses have prompted caution across the hardware sector, weighing directly on Seagate stock ahead of its earnings report.

Technical Analysis

STX remains in a strong longer-term uptrend, trading about 28% above its 100-day SMA ($695.65) and roughly 78% above its 200-day SMA ($500.62), which keeps the bigger picture tilted bullish despite the premarket dip. In the near term, it’s only modestly above the 20-day SMA ($878.33) and 50-day SMA ($886.61), so the stock doesn’t have much "cushion" if selling pressure builds.

Momentum is neutral: RSI at 52.90 suggests the move isn’t stretched to an overbought or oversold extreme.

• Key Resistance: $937.50
