Nippon Telegraph and Telephone said it plans to buy back as much as 200 billion ( 1.4 billion) of its shares, joining a growing list of such measures bolstering the Japanese market. The buyback will take place from May 12 through March 31 and is geared toward lifting capital efficiency and boost shareholder returns, the company said in a statement on Friday. Shares of Japan's biggest telecom operator were up about 3.4% as of 1:40 p.m. in Tokyo, off its day's high of 5.6%. NTT also forecast full-year operating income and announced quarterly profit that trailed analyst estimates. The buyback news comes on the heels of a decision to take over NTT Data Group in a deal worth 2.37 trillion -- a move it said would speed up its ability to make big bets on artificial intelligence.

Masayoshi Son, the billionaire boss of SoftBank Group Corp., has long presided over a quarterly earnings ritual of zany slide presentations. One included a goose laying multibillion-dollar golden eggs and another flock of unicorns flying upward along a chart of growth in artificial intelligence. Mr. Son is planning to step back from the routine when the giant technology investor delivers its earnings Friday, instead greeting attendees with short remarks before handing the baton to his chief financial officer, according to a SoftBank agenda for the event. It is slated to be a more sedate presentation than those from Mr. Son, who also isn't planning on taking questions from the media, according to people familiar with the company. The more subdued role--which is likely to continue, the people said--comes as Toyko-based SoftBank, the world's most active startup investor in recent years, is in the midst of a difficult run.

This thesis investigates share buybacks, specifically share buyback announcements. It addresses how to recognize such announcements, the excess return of share buybacks, and the prediction of returns after a share buyback announcement. We illustrate two NLP approaches for the automated detection of share buyback announcements. Even with very small amounts of training data, we can achieve an accuracy of up to 90%. This thesis utilizes these NLP methods to generate a large dataset consisting of 57,155 share buyback announcements. By analyzing this dataset, this thesis aims to show that most companies, which have a share buyback announced are underperforming the MSCI World. A minority of companies, however, significantly outperform the MSCI World. This significant overperformance leads to a net gain when looking at the averages of all companies. If the benchmark index is adjusted for the respective size of the companies, the average overperformance disappears, and the majority underperforms even greater. However, it was found that companies that announce a share buyback with a volume of at least 1% of their market cap, deliver, on average, a significant overperformance, even when using an adjusted benchmark. It was also found that companies that announce share buybacks in times of crisis emerge better than the overall market. Additionally, the generated dataset was used to train 72 machine learning models. Through this, it was able to find many strategies that could achieve an accuracy of up to 77% and generate great excess returns. A variety of performance indicators could be improved across six different time frames and a significant overperformance was identified. This was achieved by training several models for different tasks and time frames as well as combining these different models, generating significant improvement by fusing weak learners, in order to create one strong learner.

That's the message of a big Wall Street Journal post-mortem on Watson, the IBM project that was supposed to turn IBM's computing prowess into a scalable program that could deliver state-of-the-art personalized cancer treatment protocols to millions of patients around the world. Watson in general, and its oncology application in particular, has been receiving a lot of skeptical coverage; STAT published a major investigation in 2017, reporting that Watson was nowhere near being able to live up to IBM's promises. After that article came out, the IBM hype machine started toning things down a bit. But while a lot of the problems with Watson are medical or technical, they're deeply financial, too. As of 2018, IBM is shrinking: In 2011, when the company first introduced the idea that Watson might be able to one day cure cancer, its revenues were $107 billion.

Watson in general, and its oncology application in particular, has been receiving a lot of skeptical coverage of late; STAT published a major investigation last year, reporting that Watson was nowhere near being able to live up to IBM's promises. After that article came out, the IBM hype machine started toning things down a bit. But while a lot of the problems with Watson are medical or technical, they're deeply financial, too. IBM is shrinking: In 2011, when the company first introduced the idea that Watson might be able to one day cure cancer, its revenues were $107 billion. They've gotten smaller every year since, ending up at $79 billion in 2017.

South Korean tech giant Samsung Electronics logged a record profit of 11.2trn won – $10bn (£7.6bn) – in the July to September period, it said on Tuesday, its best for any quarter. The world's biggest memory chip and smartphone maker had its de facto leader jailed in August for bribery and faced a recall of its flagship Galaxy Note 7 device. But its net profits soared 148% on the same period a year ago, it said in a statement, thanks to strong demand for its memory chips and a recovery in smartphone sales with the roll-out of the new generation Galaxy Note 8. The figures come only two weeks after chief executive Kwon Oh-Hyun resigned, saying the South's biggest firm was facing an "unprecedented crisis" and its current profitability was "merely a fruit of decisions and investment made in the past". The firm described Tuesday's numbers as an "overall robust performance".

Warren Buffett isn't known for blown calls. But the billionaire investment guru and head of the holding company Berkshire Hathaway has become increasingly touchy around one of his top positions: International Business Machines. "We feel fine or we won't own it. We've never sold a share of IBM," Buffett told CNBC in an interview Monday. The fact that shares in the computing giant have fallen some 15 percent since he first started building his stake in the company in early 2011 hasn't phased him.

As a reminder, all participants' lines will be in the listen-only mode. There will be an opportunity for you to ask questions after the presentation concludes. I would now like to hand the conference over to Mr. Aravind Viswanathan. Thank you and over to you, sir. We will begin the call with business highlights and overview by Abid, the Chief Executive Officer and Member of the Board, followed by the financial overview by our CFO, Jatin Dalal. Afterwards, the operator will open the bridge for Q&A with our management team. Before Abid starts, let me draw your attention to the fact that during this call, we may make certain forward-looking statements within the meaning of Private Securities Litigation Reform Act 1995. These statements are based on management's current expectations and are associated with uncertainties and risks, which may cause the actual results to differ materially from those expected. The uncertainties and risk factors are being explained in our detailed filings with the SEC. Wipro does not undertake any obligation to update the forward-looking statements to reflect events and circumstances after the date of filing thereof. The conference call will be archived and the transcript will be available on our website. Ladies and gentlemen, let me now hand it over to Mr. Abid. Today is the first opportunity for me to interact with all of you since I've taken over as the Chief Executive Officer of Wipro, and it's a special moment for me. While I will speak about the performance of our full quarter and the full fiscal year, I thought I will take this opportunity to begin by speaking about our ambition, our strategy and how we are going to execute this strategy. Since I got announced within two days, I was able to define and announce my structure and I had already preselected my leadership team which I announced on 6th of January, effective February 1. Over the past 80 days after I have taken over as CEO, I've had the opportunity to go around the globe and meet about 70 of our top 100 clients. And both with my leadership team and with the customers, I've had the opportunity to validate the strategy that we have been working on and this gives me a high level of confidence on the relevance of our overall strategy. Our ambition is to double our revenues to 15 billion by fiscal 2020 with a 23% operating margin.
