SBI Securities downgrades SoftBank Group (9984) to 'Neutral'
SBI Securities downgraded SoftBank Group Corp. from 'Buy' to 'Neutral', sending shares down 3.8% on 28 May 2026. The Japanese conglomerate's shares are currently trading at ¥6,997, down from yesterday's close of ¥7,272. This reassessment by the brokerage firm tempered recent optimism surrounding SoftBank's substantial investments in AI data centres and speculation regarding a potential US listing for its portfolio company, OpenAI.
The downgrade prompted investors to secure profits following a recent surge in the stock. This sentiment was exacerbated by a decline of over 5.7% in the US-listed shares of SoftBank's chip design subsidiary, Arm Holdings. SoftBank Group had previously garnered significant market attention for its AI strategy, with analysts raising target prices, as noted in a 28 May 2026 report.
Today's decline extends a 2.5% drop on 27 May 2026, underscoring the volatility inherent in AI-related investments. The market continues to monitor the company's AI strategy progress and any concrete developments concerning OpenAI's initial public offering.
Why an Analyst Downgrade Shifts SoftBank Group's Outlook
SoftBank Group is a Japanese investment powerhouse, known for pouring capital into technology companies globally. They operate by identifying promising startups and established tech firms, investing in them, nurturing their growth, and eventually selling their stakes for a profit. This model positions them as a significant driver of innovation in the tech sector, with their earnings directly tied to the success of their diverse portfolio.
Today's decline in SoftBank Group's share price largely stems from SBI Securities downgrading its investment rating on the company from "Buy" to "Neutral". Investment banks employ analysts who meticulously assess a company's financials, growth prospects, and industry trends to form an opinion on its future stock performance. These ratings, such as "Buy", "Neutral", or "Sell", signal a shift in market expectations, prompting other institutional and individual investors to re-evaluate their positions, which can significantly influence share prices. This comes as previous gains from AI data centre investments and potential OpenAI US listing are tempered, alongside a more than 5.7% fall in subsidiary Arm's US stock encouraging profit-taking.
Consequently, SoftBank Group's stock is currently trading at ¥6,997, marking a 3.8% drop from its previous close of ¥7,272.
Think of it like a highly anticipated film that was initially lauded by critics as a "must-see masterpiece". If a prominent film critic then revises their review to "a good, solid film", the movie itself hasn't changed. However, this shift in expert opinion can temper audience enthusiasm and reduce box office projections, as the perceived expectation has been lowered.
