Main concern is mega caps and AI. Hyperscalers borrowing on bond and equity side. Big question: will rate of return be realized? So far earnings growth positive, fueling further rise. Vanguard expects some sort of correction in equity markets over the long term. Expect rotation toward value stocks and more value outside US. US and tech potentially overvalued.
Two scenarios: if AI delivers transformative productivity, correction is smaller. If not, readjustment and correction is larger.
