Buy opportunity soon

After two consecutive positive earnings' reports, NYSE:PLTR skyrocketed. Now, on a technical aspect I see a retracement as there is a clear Head and Shoulders formation. On a financial stand-point, the P/E ratio of 78 is relatively high and considering the current environment, full of expensive debt.

I sold 25% of my NYSE:PLTR along the way up but missed out on $20 by a significant 30%, I will look to accumulate my 25% position back when the price retraces.
