The assessment is 'likely_true' with high confidence based on strong, corroborating evidence. The most relevant source, a news article from ad-hoc-news.de, directly and explicitly supports the entire statement. Its headline, "Retail Investors Exit Apple as AI Rivals Attract Capital," and its content specify net inflows of +$15 billion to Nvidia and +$6 billion to Tesla from retail investors. This primary piece of evidence is strongly reinforced by a LinkedIn post from a capital management firm, which independently states that retail investors have invested over $15 billion into Nvidia, directly corroborating a key quantitative claim. While this second source doesn't mention Apple or Tesla, its alignment on the Nvidia figure significantly boosts the credibility of the primary news report. Furthermore, multiple articles from AOL, a source with moderate-to-high authority, repeatedly cite VandaTrack Research as a reputable source for granular data on retail investor capital flows. This establishes that such specific tracking is common and lends plausibility to the figures reported in the primary sources. While other high-authority sources from BNY Investments and Northwest Capital Management are not specific, they provide context by mentioning a general market "rotation" among large tech stocks like Apple, Nvidia, and Tesla, which is consistent with the claim. There is no contradictory evidence among the provided sources. The convergence of a direct claim, specific data corroboration, and contextual support makes the original statement highly probable.
