A technical analyst for which I have great respect today issued a call with a downside target of 140-150 on FB. But he discussed the potential for buying dips around that level if exhaustion looks present. However, it's unclear whether he was suggesting buying the dip as a shorter-term trade or a longer-term buy-and-hold investment.
In my view, a 5-wave move downward may mean a bounce after ward. If the 5-wave move down constitutes the larger-degree Wave 1, or whether it constitutes a larger-degree Wave A, more downside is possible (many months out, possibly 2023) as either Wave 3 or Wave C of the larger degree trend. I have not done EW analysis going back on FB into the prior years leading to the peak, as that process would be very time consuming and unnecessary for trading purposes. If I see an intermediate-term 5-wave move beginning at a major low or peak, that can work for trading ideas.
