@coldjoint,
Trump was partially correct; his anti-regulation and tax policies — and an inherited underlying healthy economy —
did give the stock market a boost. But bragging about it the way he did was stupid because you never know that forces will affect the market and whether you'll have control over them. And now the change in values over the past weeks is due to uncertainty over the effects that raising tariffs and wrecking trade deals has on certain sectors of our economy and on world trade,
policies for which Trump is directly responsible. So no, I don't think the current drop can be blamed on Obama.
