Check out the companies making headlines in midday trading. Microsoft — Shares jumped 3% as investors cheered the Xbox maker’s fiscal first-quarter results released Tuesday. Microsoft posted almost 13% year-over-year revenue growth, and its Azure cloud segment saw revenue gain 29% for the quarter. The Windows software maker also posted a rise in profit due to slower operating expense growth. Alphabet — Shares of the Google parent dropped 9.5%, putting it on pace for the worst day in nearly a year, after the dominant search engine owner reported cloud revenue that missed analysts’ expectations. Norfolk Southern — The freight railroad dropped 5.3% on the back of disappointing third-quarter earnings. Norfolk Southern earned $2.65 per share, excluding items, while analysts polled by LSEG, formerly known as Refinitiv, estimated a profit of $2.69 per share. Revenue was about in line with expectations. General Dynamics — Shares of General Dynamics rose 4% after the defense contractor’s third-quarter earnings and revenue topped estimates. General Dynamics posted earnings of $3.04 per share on revenue of $10.57 billion against analyst estimates of $2.91 in earnings per share and $10.05 billion in revenue.
