Clearly symbolize the hypotheses and the conclusions of the argument using appropriate symbols and logical connectives. Then, write the entire argument symbolically (in the form A B). If the argument is valid, present a proof sequence. Otherwise, justify that the argument is invalid.

If the stock market does not decline then it is the case that Trump wins and Warren does not run. If Biden does not run then Warren runs. If Biden runs then Hillary does not run. Therefore, if Hillary runs, then the stock market declines.
