Notable Price Movement
- Oct 12-16$639.0118.39%
STX fell 15.09%, from $887.09 on October 5 to $753.25 on October 12. The decline was front-loaded: shares dropped to $805.63 on October 6, slipped further to $774.83 by October 8, rebounded modestly to $783.00 on October 9, then fell to $753.25 on October 12. The supplied evidence does not identify company-specific news or a broader market move that explains this price action; the TDK-related headline provides no deal details, and Wells Fargo’s reported target cut is dated October 16, after the stated endpoint. Volume was highest on October 6, at 7.3 million shares, during the sharpest daily drop. No market benchmark or sector performance is provided to establish a market-context explanation.
- Oct 5-9$783.007.77%
STX fell 11.80%, from $913.45 to $805.63, after first rising to $945.57 on October 1 and then reversing sharply. The largest move came October 2, when the stock dropped to $848.99 on volume of 13.6 million shares; coverage associated the selloff with renewed concern about Toshiba’s capacity expansion and competition. The decline also came amid weakness across storage and memory stocks, suggesting sector pressure compounded company-specific concerns. STX rebounded 4.5% to $887.09 on October 5, but gave back that gain and more on October 6, falling 9.2% to $805.63. News also highlighted a $17.4 million sale by Seagate’s CEO the day before the Toshiba-related drop, though the evidence does not establish it as a cause.
- Sep 28 - Oct 2$848.997.40%
Seagate rose $39.65, or 4.38%, from $905.92 to $945.57. The shares advanced to $921.51 on Monday, slipped to $913.45 on Tuesday, then recovered on Wednesday and added further gains Thursday to finish at the period high. The supplied evidence identifies no company-specific announcement as the main catalyst. The broader backdrop was supportive at points: market coverage linked gains to weak US economic and payroll reports easing concerns about further Federal Reserve rate hikes, and to bond yields falling; another report described a market retreat as yields surged. Coverage also cited hopes for a US-Iran deal supporting a later market advance. Seagate’s gains therefore came amid changing macro sentiment and an AI-storage demand backdrop, not a clearly documented company event.
- Sep 21-25$916.836.76%
STX gained 17.96%, rising from $783.18 to $923.86, with a steady climb across every provided session and no material reversal. The stock added ground on September 17–18 and extended the advance on September 21–23, while trading volume peaked at 6.98 million shares on September 18 before easing. Trefis described the move as part of a six-day winning streak, and coverage pointed to Seagate’s potential AI connection and a buyback-related valuation case as supportive narratives. However, the supplied evidence does not identify a specific company announcement or establish either theme as the cause of the rally. Broader market coverage cited higher bond yields and chipmaker weakness, but did not link those conditions specifically to STX’s gains.
- Sep 7-11$830.172.25%
Seagate rose 9.17%, or $76.00, from $828.38 to $904.38 across the supplied sessions. The stock first fell for four consecutive closes, reaching $798.61 on September 3, before reversing sharply with a 6.3% gain on September 4 and another 6.5% advance on September 8; volume increased to 5.19 million shares on the final session. No company-specific earnings release, contract, or guidance change is identified in the evidence. Instead, coverage points to volatile storage-sector trading, with profit-taking after a strong prior run competing with optimism about AI-driven storage demand, tighter hard-disk-drive supply, and firmer pricing. The rebound more than erased the earlier decline.
- Aug 31 - Sep 4$849.282.35%
Seagate fell 5.74%, from $847.20 to $798.61, with the decline concentrated after the week began. Shares were nearly unchanged on Monday at $828.38, then slipped 1.42% Tuesday, 0.99% Wednesday and 1.23% Thursday, producing four consecutive lower closes. The clearest company-specific pressure was an insider-sale filing, including reported sales under preset 10b5-1 plans, alongside broader weakness in storage stocks, as cited by Quiver Quantitative. TradingKey also attributed the September 2 decline to storage-stock weakness, although it did not identify a new Seagate operating announcement. The move contrasted with earlier enthusiasm around AI-driven storage demand and a reported 5% rally in Seagate alongside SK Hynix, suggesting the week was primarily a reversal in storage-sector momentum.
- Aug 24-28$829.762.38%
Seagate fell $20.24, or 2.38%, over the week, from $850.00 to $829.76. The main setback came Monday, when STX dropped to $794.65 as chipmaker weakness pressured technology stocks; Barchart reported the Nasdaq 100 fell 0.97% that session, while Zacks cited broader tech selling and Middle East-related economic concerns. The stock then reversed sharply, gaining 3.40% Tuesday and 3.01% Wednesday to recover most of Monday’s loss, with storage and AI-demand commentary supporting the sector. It held nearly flat Thursday before giving back $17.44, or 2.06%, Friday. The supplied evidence identifies no new company-specific announcement explaining the full-week decline, so market-wide chip volatility and profit-taking appear more relevant.
- Aug 10-14$973.4419.77%
STX fell $30.07, or 3.62%, from $831.06 to $800.99 over the supplied Aug. 3-10 trading window. The stock gained $14.29 on Aug. 4, slipped $7.69 on Aug. 5, and added $15.29 on Aug. 6, with early strength coinciding with coverage of earnings-driven target increases and $1,000-plus valuations. It then reversed sharply, dropping $40.19 on Aug. 7 on the week’s heaviest volume before losing another $11.77 on Aug. 10. The evidence does not identify a specific company announcement, guidance change, or market catalyst behind the late-week selloff. Broader market context is also not supplied, leaving the reversal unexplained beyond profit-taking or sentiment deterioration after the initial rally.
- Aug 3-7$812.765.07%
Seagate rose $98.05, or 13.12%, from $747.30 to $845.35 over the supplied week. The main catalyst was the market’s favorable reaction to Seagate’s strong earnings report, which reinforced expectations for AI-driven data-center storage demand, tighter hard-disk-drive supply and firmer pricing. Broader technology strength added support: the Nasdaq 100 gained 3.36% on Thursday as Microsoft led a tech rally, while other sessions cited Amazon’s results and easing Middle East tensions. The stock advanced through July 31, reaching $856.13, then gave back part of the move on August 3 by falling to $831.06 before rebounding to $845.35 on August 4. The evidence does not identify a new company-specific announcement during the final two sessions.
