BlackRock CEO Larry Fink has issued a warning against excessive optimism surrounding the stock market recovery rally, hinting at a possible 20% decrease. This caution stems from the looming threat of significant US tariffs and apprehensions about a shrinking US economy. Fink highlighted that a majority of CEOs share the belief that the US is presently navigating through a recession, further exacerbated by the potential inflationary impact of tariffs.
