&lt;p&gt;In traditional portfolio management, assets are categorized into single-layer taxonomies (such as GICS sectors or market cap buckets). However, in the AI-driven tech expansion, linear categorization causes severe information collapse—for instance, &lt;code&gt;NVDA&lt;/code&gt; acts both as compute infrastructure (Value Chain: Compute) and a strategic core defensive holding (Portfolio Layer: CORE); whereas &lt;code&gt;CRWD&lt;/code&gt; represents AI cybersecurity leadership (Value Chain: AI_Security) with high elasticity expansion properties (Portfolio Layer: EXPANSION).&lt;/p&gt;</description></item></channel></rss>
