Earlier today, _The Information_ reported that the tech giant is developing a next-generation AI server chip powered by Gemini, with a planned 2028 launch. Furthermore, AT&T (T) and T-Mobile (TMUS) were both top performers ahead of their earnings on July 22 and July 23, respectively. Several communication services stocks led the sector's gains, including: - Alphabet (GOOGL) - T-Mobile (TMUS) - Take-Two Interactive (TTWO) - AT&T (T) - Omnicom (OMC) ## **Today's Worst-Performing Sector** Meanwhile, the healthcare sector faced the largest drawdown. Moderna (MRNA) continued to sell off, bringing its five-day loss to 10%. In addition, the sector as a whole faced pressure from a rising 10-year Treasury yield. With higher yields, earnings expected further in the future are discounted more heavily, weighing on valuations. Healthcare stocks are especially sensitive to higher yields because a larger share of their value is generally tied to long-term earnings expectations. Notable healthcare stocks trading lower include: - Moderna (MRNA) - Revvity (RVTY) - Mettler-Toledo International (MTD) - Waters Corp (WAT) - Biogen (BIIB) ### Related Stocks - [MRNA.US](https://longbridge.com/en/quote/MRNA.US.md) - [GOOG.US](https://longbridge.com/en/quote/GOOG.US.md) - [TMUS.US](https://longbridge.com/en/quote/TMUS.US.md) - [RVTY.US](https://longbridge.com/en/quote/RVTY.US.md) - [GOOGL.US](https://longbridge.com/en/quote/GOOGL.US.md) - [T.US](https://longbridge.com/en/quote/T.US.md) - [.SPX.US](https://longbridge.com/en/quote/.SPX.US.md) - [DTEGY.US](https://longbridge.com/en/quote/DTEGY.US.md) - [SPY.US](https://longbridge.com/en/quote/SPY.US.md) - [VOO.US](https://longbridge.com/en/quote/VOO.US.md) - [GOOW.US](https://longbridge.com/en/quote/GOOW.US.md) - [IVV.US](https://longbridge.com/en/quote/IVV.US.md) - [GGLS.US](https://longbridge.com/en/quote/GGLS.US.md) - [MAGX.US](https://longbridge.com/en/quote/MAGX.US.md) - [MRNX.US](https://longbridge.com/en/quote/MRNX.US.md) - [MRNY.US](https://longbridge.com/en/quote/MRNY.US.md) - [GOOY.US](https://longbridge.com/en/quote/GOOY.US.md) - [GOU.US](https://longbridge.com/en/quote/GOU.US.md) - [GOOX.US](https://longbridge.com/en/quote/GOOX.US.md) - [GOOP.US](https://longbridge.com/en/quote/GOOP.US.md) - [GGLL.US](https://longbridge.com/en/quote/GGLL.US.md) - [SPLG.US](https://longbridge.com/en/quote/SPLG.US.md) - [SPXL.US](https://longbridge.com/en/quote/SPXL.US.md) - [UPRO.US](https://longbridge.com/en/quote/UPRO.US.md) - [SSO.US](https://longbridge.com/en/quote/SSO.US.md) - [SH.US](https://longbridge.com/en/quote/SH.US.md) - [SPXS.US](https://longbridge.com/en/quote/SPXS.US.md) - [SPXU.US](https://longbridge.com/en/quote/SPXU.US.md) - [SDS.US](https://longbridge.com/en/quote/SDS.US.md) - [SPYI.US](https://longbridge.com/en/quote/SPYI.US.md) - [JEPI.US](https://longbridge.com/en/quote/JEPI.US.md) - [XYLD.US](https://longbridge.com/en/quote/XYLD.US.md) - [TTWO.US](https://longbridge.com/en/quote/TTWO.US.md) - [OMC.US](https://longbridge.com/en/quote/OMC.US.md) - [MTD.US](https://longbridge.com/en/quote/MTD.US.md) - [WAT.US](https://longbridge.com/en/quote/WAT.US.md) - [BIIB.US](https://longbridge.com/en/quote/BIIB.US.md) - [T-A.US](https://longbridge.com/en/quote/T-A.US.md) - [TBB.US](https://longbridge.com/en/quote/TBB.US.md) - [T-C.US](https://longbridge.com/en/quote/T-C.US.md) - [TMUSL.US](https://longbridge.com/en/quote/TMUSL.US.md) - [TMUSZ.US](https://longbridge.com/en/quote/TMUSZ.US.md) - [TMUSI.US](https://longbridge.com/en/quote/TMUSI.US.md) ## Related News & Research - [AT&T stock has been quietly rallying since the start of July.
