On taking office in Jan 2009, President Obama introduced Quantitative Easing and Zero Interest Rate Policy, immediately stimulating the markets into recovery from the economic collapse of 2007/ 2008. Money was induced back into equities; share prices followed a steep upslope, (with economic recovery following), until QE
and ZIRP ended in 2015. The correction marking the end of QE
and ZIRP may not be quite complete, but the resumption of a normal upslope is imminent if not already begun. Obama economic policies were successful.
