Check out the companies making headlines in midday trading.

Boeing — Shares of the aerospace giant rose 1.1% after Boeing delivered third-quarter earnings that were below what Wall Street expected but, overall, did not feature any new surprises as the company works through its 737 Max aircraft crisis. While Boeing's revenue slid and the company cut production of its 787 Dreamliner program, Credit Suisse said on the whole that "no incremental negative news on MAX will be a relief for most" investors.

CrowdStrike — Shares of software company CrowdStrike rose 3.6% after Nomura Instinet initiated coverage of the stock with a buy rating. The firm said the cybersecurity company that it had "superior" proprietary technology.

Texas Instruments — Shares of the semiconductor name dropped 7.5% after the company missed revenue estimates and gave weak guidance for the current quarter. Softening demand as well as the ongoing trade war continue to pressure sales, the company said.

Six Flags — Shares of Six Flags tanked 12.4% after posting dismal third-quarter earnings. The amusement parks operator reported earnings of $2.11 per share, well below the estimated $2.31, according to Refinitiv. Six Flags earned $621 million in revenue, missing estimates of $644 million.

Eli Lilly — Shares of the pharmaceutical company fell 2.2% after reporting mixed results for the third quarter. EPS came in at $1.48, which is 7 cents above estimates, but revenue missed expectations, according to Refinitiv.
