Time Warner Cable Inc (NYSE:TWC)

Time Warner Cable Inc (NYSE:TWC) reported its third quarter earnings, and it brought some disappointing news.

In the quarter, the company lost 140,000 residential video subscribers; this exceeded the 128,000 forecast by analysts. It also added less Internet and voice customers than analysts had forecast–a sign that the company is struggling to market its service bundles to customers, reported Bloomberg.

Financial numbers for the quarter included a net income rise to $808 million ($2.60 a share), up from $356 million ($1.08 a share) in the previous year. Excluding one-time items, earnings per share were $1.41; this missed analysts’ estimates of $1.43.

The market reacted to the news with Time Warner’s stock falling 6.9 percent to $91.40 by mid-morning; it represented its largest intraday drop since October 2011.

The shares were the greatest decliner in the Standard & Poor’s 500 Index on Monday, closing down 6.36% to $91.93.

HSBC Holdings plc (NYSE:HSBC)

HSBC Holdings plc (NYSE:HBC) (LON:HSBA) reported its third quarter net profit dropped to $2.8 billion, as compared to the previous year’s $5.5 billion. The company also said it incurred a $1.7 billion quarterly charge on the value of its own debt, reported the New York Times.

Without the adjustments, the bank announced that its third quarter pretax profit more than doubled, to $5 billion. This number came in lower than analysts’ estimates.

The bank also said on Monday that it put aside $1.1 billion combined for the ongoing money-laundering investigation and a settlement for the sale of inappropriate financial products; the bank added it could see criminal charges in the United States.

HSBC Holdings plc (NYSE:HBC) (LON:HSBA)’s chief executive, Stuart T. Gulliver said in a conference call, “We deeply regret what took place took place in the United States and Mexico. A number of people have left the bank and have had clawbacks against their compensation.”
