How This Could Play Out
First assessed Oct 28
Resolved
POSSIBLEMega-cap tech valuations compress as investors rotate toward fundamentals-driven selection, narrowing the valuation premium of the group relative to broader market indices.
Status quo
LIKELYVolatility in individual mega-cap tech stocks rises while correlation remains low, increasing hedging costs for passive index trackers and forcing active managers to justify position-level conviction.
Worsens
POSSIBLEDispersion widens sharply as earnings misses or regulatory action hits individual names, triggering forced selling in concentrated portfolios and amplifying drawdowns in tech-heavy allocations.
