International Business Machines last night posted a bigger-than-expected drop in revenue and cut its full-year profit forecast.

This comes after a stronger US dollar accentuated weakness in demand from China and emerging markets. 

It was the 14th quarter in a row that IBM has posted a reduction in revenue.

The world's largest technology services company is in the middle of getting rid of low-margin businesses.

But so far it has failed to make up the shortfall with newer initiatives in the more lucrative area of cloud computing. 

Its operations in China was particularly hard hit, with fewer big deals causing revenue from that country to fall 17%, IBM's chief financial officer said on a conference call with analysts. 

Sales in Brazil, Russia, India and China combined were down 30%. 

IBM, which gets more than half its business from overseas, said overall revenue from continuing operations was cut 9% by a strong US dollar, which is up about 17% from a year ago against a basket of currencies. 

The company's total revenue fell 13.9% to $19.28 billion in the quarter, below analysts' average forecast of $19.62 billion. 

Martin Schroeter, IBM's CFO, pointed to weakness in its consulting and storage businesses for the revenue shortfall, after taking currency moves and discontinued business into account.  

"I would characterise it as the consulting and systems integration business moving away from these large, packaged applications and the storage business moving to flash and to the cloud," Schroeter told Reuters. 

Flash is a speedy type of memory used in mobile phones and other types of electronic devices.

IBM lowered its full-year 2015 operating profit forecast to a range of $14.75 to $15.75 per share from $15.75 to $16.50. Analysts on average were expecting $15.68, according to Thomson Reuters. 

The company is shifting away from hardware to the cloud, much like established rivals such as Oracle and Microsoft.

Each is striving to boost Internet-based software and services sales to compete with the likes of Salesforce.com and Amazon.com.

In August, IBM said it would buy medical image company Merge Healthcare in a $1-billion deal and combine it with its newly formed health analytics unit, which is powered by its famous Watson supercomputer. 

Revenue from what the company calls "strategic imperatives," which include cloud and mobile computing, data analytics, social and security software, rose about 17% in the third quarter ended September 30. 

Yet the new businesses have so far failed to make up for revenue lost to divestitures. 

The company known as 'Big Blue' has been selling low-margin businesses such as cash registers, low-end servers and semiconductors to focus on high-growth areas such as security software and data analytics, besides cloud-based services. 

IBM said its net income from continuing operations fell to $2.96 billion, or $3.02 per share, from $3.46 billion, or $3.46 per share, a year earlier. 

Excluding items, IBM earned $3.34 per share from continuing operations in the latest quarter, beating the average analyst estimate of a profit of $3.30 per share.
