Most Popular Narrative: 23% Overvalued

SoftBank Group’s latest fair value estimate of ¥16,199 sits well below its last close near ¥19,980, reflecting a significant gap between analyst projections and current market optimism.

The prevailing narrative centers on AI adoption as an unstoppable growth engine across industries. However, high valuations now may ignore the risk that normalization of interest rates and tighter funding could compress multiples for high-growth, capital-intensive private tech ventures. This could lead to lower Vision Fund investment returns and potential write-downs, reducing net margins and earnings stability.

Another View: Market Multiples Send a Different Signal

Another way to look at SoftBank Group’s valuation is through its price-to-earnings ratio. At 16.4x, the ratio is lower than both the industry average (20x) and the peer average (16.4x), and it sits beneath the fair ratio of 17.4x. This suggests the stock may offer relative value compared to competitors. But are these price gaps a sign of true bargain, or do they reflect deeper risks for investors ahead?
