The assessment is based on a strong consensus among multiple, highly authoritative, and directly relevant primary sources. Reputable financial news outlets like Morningstar/Marketwatch and TipRanks explicitly state that SoftBank shares fell by 10.9% and 'about 11%', respectively. This is further corroborated by an investment research platform, Smartkarma, which notes an '-11% Plunge', and a Yahoo Finance article reporting a '10% SoftBank plunge'. These figures directly support the statement that the shares fell by 'more than 10%'. There is no conflicting evidence among the provided sources; the less relevant articles discuss general market trends without contradicting the specific claim about SoftBank. The consistency and high credibility of the core sources provide a high degree of confidence in the statement's truthfulness.
