TE Connectivity stock is among today’s notable decliners. Why is TE stock down today?

Samsung’s Q2 Preview Triggers Sector‑Wide Rethink on AI SpendingWhat DeepSeek’s Custom Chip Development Means for AI DemandA Reuters report on DeepSeek is adding a second layer of concern. The Chinese AI laboratory has been quietly assembling a team of semiconductor engineers and engaging with chip designers, foundries and memory suppliers as it works toward building a homegrown processor optimized for inference workloads. The initiative has been underway for about a year without any public acknowledgment from the company.Success would allow DeepSeek to wean itself off third party hardware from Nvidia and Huawei that it has historically depended on to power its models. The accelerating push by major AI labs to control more of their own compute stack is feeding anxiety that demand for outside semiconductors could come in softer than the market had been pricing in a concern that is dragging chip-linked names.Critical Technical Levels for T1 Energy StockT1 Energy is under short‑term pressure after its latest pullback. The stock trades 17.8% under its 20‑day simple moving average at $8.75 and 9.7% under its 50‑day simple moving average at $7.97, which places the chart in a broken short‑term trend. At the same time, price remains 17.7% above its 200‑day simple moving average at $6.11, so the longer‑term trend has not fully reversed.Momentum has also cooled. MACD sits below its signal line and the histogram is negative, a setup that usually shows sellers controlling the near‑term rhythm unless buyers can reclaim that baseline. When MACD holds under the signal line, rallies often lose strength even if the broader trend is still pointed higher.
