Stocks have hit a succession of all-time highs in recent months amid unusually low volatility and despite a market that some analysts view as overvalued. That run-up also has been fueled by expectations for tax cuts, which means stocks could decline if talks over fiscal stimulus in Congress hit an impasse. Goldman Sachs analysts forecast that the S&P 500, which is hovering at a record high of 2,556 points, would fall to 2,400 if tax reform fails.
