Back to tracking stock market

There were too many events with Covid lock down, opening up and people starting to go out again. In the middle of it stock market went down, up and now it is going down again. Story now is interest rates are going up to contain inflation. This is where we are now -

S&P 500 (SPY) : $364. PE ratio is 18.4. (source: https://www.multpl.com/s-p-500-pe-ratio) 

There are stocks which seem to have low valuation, at least a PE ratio I have not seen them trade at for a long time.

INTC : $26.5.     PE: 5.7

META: $138.2.   PE: 11.2

QCOM: $116.     PE: 10.3

GOOG: $97.7.    PE: 18.2

AAPL: $143.      PE: 23.7

Meta (or FB) dropped further lower to $120 as of Dec 30, 2021. I typically look at PE ratio to see if something is overvalued. META is trading at PE of 11.5 at this price. But what makes it attaractive is operating cash flow is $54billion, which is 1/6th of market cap of $314billion - or 17.2% of market cap. For comparison AAPL market cap is $2.07 trillion and operating cash flow is $120billion, which makes cash flow to be 5.7% of market cap.
