the market expands because someone or a group of someones thinks the underlying equities are worth more or will be worth more than the current price of the equity. the fed could raise rates to 100% and as long as a company can sell their goods and services for a bigger profit, it won't drag that equity down without the perception that the future will be bad.
the reason the markets have been on a tear is that there are other parts of the world that are consuming goods and services that they have never bought before, like Africa and Asia. once these area's become saturated, company's will have to find other area's to sell too. it could be the moon or some other planet!
since markets are correlated to the size of the population of the world and opening up their products to new parts we can understand what will bring the markets down. if there is going to be a bad war that wipes out tens of millions of people or a disease that takes people out we will see markets implode. everything else like changes in fed policies is nothing but hiccups to markets.
