Taking credit for something you can't really influence seems to be one of the favorite pitfalls for politicians. This time around, incumbent president Donald Trump suggested that soaring markets were "virtually unprecedented" under his reign. This isn't true. A glimpse at the S&P 500 since the economic crisis shows that the market has been in a bullish mood, with a few hick-ups, since 2009.
Though markets react to political indicators, such as a new president taking office, they more often seem to follow their very own rational. That’s why the jury's always out on whether, for example, a market uplift is happening because or despite of real world events, suggesting that even the Commander in Chief doesn't hold sway over the markets.
This might turn out to be a good thing, considering that the next consolidated economic downturn is sure to come. He who doesn't take credit doesn't have to take the blame either.
