Wall Street is in the midst of earnings season, and the results so far have been unprecedented. Roughly a quarter of S&P 500 companies have reported second-quarter results, and 88% have come in better than expected, reports Axios. If that trend holds up, it would be the highest percentage since FactSet started collecting data in 2008. What's more, companies aren't just beating expectations, they're crushing them. Earnings are coming in 19% higher than analysts' forecasts, well above the five-year average of 7.8%. This week will be the big test, however, given that 165 companies in the S&P index report earnings, including heavyweights Apple, Amazon, Alphabet, Facebook, and Tesla, notes CNBC.
