The bank saw weaker investment banking activity during the quarter, although it said results in equity and fixed income were strong. Morgan Stanley lost 2.6% in the premarket.

Taiwan Semiconductor (TSM) – The chip maker’s stock rose 1.5% in the premarket after second-quarter earnings beat analyst estimates. Taiwan Semi also raised its revenue forecast for the year. Results got a boost from strong markets for automotive and IoT chips.

Twitter (TWTR) – Twitter added 1.1% in premarket action, on top of a 12.6% jump over the past 2 sessions.

Twitter also said in an SEC filing that it is not planning company-wide layoffs but may continue to restructure the company.

Conagra (CAG) – The food producer reported an adjusted quarterly profit of 65 cents per share, 2 cents above estimates, with revenue essentially in line with forecasts. Conagra saw an impact from higher costs, with operating margins falling by 310 basis points.

Cisco Systems (CSCO) – J.P. Morgan Securities downgraded the networking equipment maker’s stock to “neutral” from “overweight,” based in part on what it sees as downside risks to enterprise spending levels. Cisco fell 2.2% in the premarket.

Dollar General (DG) – The discount retailer’s stock fell 2.3% in the premarket after Citi downgraded it to “neutral” from “buy,” noting that the shares are within 4% of its price target. Citi also feels the recently announced CEO transition will be smooth and does not impact its view of the stock.
