Shares of Sony popped on Wednesday morning, touching a nine-year high after rising more than 11 percent early in the session.
The move in share price came after the Japanese consumer electronics giant revised upward its profit forecast for the fiscal year ending Mar. 31, 2018, and announced expectation-topping quarterly results on Tuesday.
The company said it expected full-year profit to come in at 630 billion yen ($5.5 billion) — a 26 percent increase from the 500 billion yen it had forecast in August. The revised profit figure was substantially higher than Sony's record 525.7 billion yen profit in 1998 and the 585.5 billion yen the company had been forecast to make this year, according to a Thomson Reuters Starmine SmartEstimate survey.
Reasons for the upward revision included strength in the semiconductor and home entertainment segments, as well as amendments to the assumed foreign exchange rates, the company said.
Meanwhile, Sony's operating profit for the quarter ending Sept. 30, 2017, rose 346 percent to 204 billion yen ($1.79 billion), beating the 140.5 billion yen estimated in a Reuters survey.
"This is not your granddad's Sony," Michael Robinson, chief technology strategist at Moneymorning.com, told CNBC's "Squawk Box," indicating that restructuring efforts at the company that began in 2014 under CEO Kazuo Hirai had paid off.
