Stock Market a Casino? That's Unfair to Casinos

Consider that the S&P 500 declined by nearly 50 points between 12:30 p.m. Friday and 1:45 p.m. yesterday on little news, then rebounded more than 20 points between about 3:15 p.m. and the close. S&P 500 futures then fell broadly last night, but have rallied vigorously this morning to extend yesterday afternoon’s late rally – again, on no real news.
