**OCT 12** In the leadup to Amazon Prime Day (Oct. 13), the company’s stock rises in anticipation of higher sales despite the pandemic, as Prime members tend to be higher-income earners

**NOV 5** With election results still pending, top tech companies in MGK soar on expectations of gridlock in Congress, which will likely stave off prospects of higher corporate taxes.

**JAN 28** Facebook’s Oversight Board overturns several of the company’s decisions to remove potentially offensive content in four of five cases, its first batch of judgments since forming in fall 2020.

**MAR 4** Inflation fears put downward pressure on tech stocks, with Tesla shares particularly hard hit. The company also faces growing competition, parts shortages and increasing costs.

**MAY 12** Tech stocks including Apple lead a market downturn spurred once again by inflation fears and concerns about sky-high market valuations in the sector.

**JUL 16** NVIDIA stock sees a multiday decline, hurt by less demand from the cryptocurrency space and news of Intel’s\* possible acquisition of Advanced Micro Devices.
