Some color from MarketWatch.com:

Thus far, about one-fifth, or 112, of the S&P 500 companies have reported already, with the majority topping analysts’ earnings estimates: 72.3% of companies have reported above analyst average estimates, compared with an average outperformance of 64%, but below the average over the past four quarters of 78%., according to data from Refinitiv.

However, 58.0% of companies have reported fourth-quarter revenue above analyst expectations, which is below the long-term average of 60% and below the average over the past four quarters of 72%, the data provider said. Moreover, earnings expectations themselves had been dialed back by analysts just before the fourth-quarter kicked off amid a panoply of headwinds.
