So earnings week for big tech (Apple, Google, Microsoft, Meta (formerly FB) and Amazon) was proclaimed to be make or brake for the S&P index.  Looking at the earnings results of the big tech companies:

Google down 9% this week.

Microsoft down 7.7%

Amazon down 15%

Meta down 24% !!  That's after being down over 50% on the year.  Possible capitulation since volume was over 200 million shares.  Might be low risk entry point.  The company isn't going under anytime soon.

Apple bucking the trend and down only 2% in overnight trading.

Now look at a chart of the S&Ps.  (After you click on the link, click on "flip charts".

The anticipation this week about the mega tech companies possibly disappointing on earnings (and they did) and wouldn't that mean that the general index would get hammered because the big tech make up so much of the index in percentage terms?  As you can see by the chart it's catching a bid when it would have made perfect sense for it to be down big.
