What can stop equity markets from rising?
The sharp rise in equity markets in the United States and the euro zone can in principle be stopped by: A shift to more restrictive monetary policies; but we expect real long-term interest rates to remain negative , which will instead continue to drive equity markets higher; Investor concern about high equity valuations; but as long as real interest rates are negative, investors cannot switch from equities to bonds; A decline in growth and corporate earnings, but corporate profitability is very strong and will probably withstand lower growth in 2022; A less favourable supply-demand balance for equities, but on the contrary, share buybacks are increasing and there is still a lot of liquidity to invest. All things considered, for the time being, only external shocks (geopolitical crises, wars) seem to be able to stop the rise in equity markets.
