Tech Sector Facing 'Earnings Bubble', Warns Goldman Sachs

Goldman Sachs has sounded an alarm about the tech sector, warning that while valuations may not be overextended, investors are facing an 'earnings bubble'. The report from Goldman Sachs Global Investment Research pointed out that despite rising growth expectations, technology stocks do not appear to be in a valuation bubble.

However, there is growing concern that the sector's strong earnings growth may not be sustainable. Investors have been questioning whether the recent surge in capital expenditure by leading tech companies will ultimately pay off.

The report noted that for about a decade after the global financial crisis, major technology companies benefited from rising demand for software and cloud computing while remaining relatively capital-light. However, the introduction of ChatGPT led to an explosion in capex among hyperscalers, eroding their premium cash flows and pushing them towards debt and equity markets for funding.

As a result, the US equity market has seen a sharp decline in free-cash-flow yield relative to more value-orientated markets such as Europe. Concerns about the future returns generated by this spending have resulted in a de-rating of dominant technology companies, with their P/E ratio now only marginally above that of other stocks in the S&P 500.
