What do you make of those? My issue is the S&P is one indicator taken in isolation that doesn't reflect the picture that really matters. For example, you can do a huge tax cut for corporations and the CEOs will use the proceeds to buy back their stock, driving the stock price up, and they do it because their compensation is based on stock performance and shareholders are the ones who control whether they will be CEOs for long and all they care about is the stock price.
So you can do things to harm the economy — for example, ballooning the national debt — and optically it looks fine because the S&P is going up even when unemployment is rising, you're not spending on science and infrastructure that builds the economy over the long term, yada. It's like companies who grow by going into debt (ahem, Trump businesses) so you think they are great until they have to declare bankruptcy.
Here's another measure, GDP:
