Not sure if this is a political talk or a legit talk about the market. Not sure how you invest, but I consider stocks along the lines of biotechs be a short term stock - and an extremely high risk one at that. I don't know how you invest, but I pull out my cash when I make 7% on them or lose more than 5% of the initial investment - at least with my 'income' investments. If you're looking for a long term stock, I suggest you look at companies that has a consistent growth - keeping in mind that the market goes up and down, even if there's a great president in the office (look at Regan and Clinton's admin). Otherwise, blaming the President for stock drops are just one factor you can throw in out of thousands - because there are numerous other stocks that have risen considerably that has nothing to do with Trump either, but I don't see anyone crediting him for those.
