HP Inc stock prices may plunge by 50%. This downside scenario was highlighted by a diamond pattern that is finally formed on HP stock prices chart. This pattern started to form since March 2021. The first exit of the price form this patter was to the downside. Well, this doesn’t guarantee prices would fall to $13.00 per share. But in case of a successful retest of the $29.00-30.00, which is the support of the pattern, a strong sell signal could emerge. I believe this is the level at $26.00 per share that would trigger this signal. If this signal would emerge a short trade targeting $13.00 would be very interesting. The stop-loss in this case could be put at $35.00.
