To buy? At current levels, downside risks from high valuation and volatility suggest caution. To hold? Yes, if you already own shares, PLTR’s solid growth, recurring contracts and AI integration support a hold strategy. To add? You might consider waiting for a pullback into the $90–$120 range before building a position. In summary: Hold is the prudent stance; strong fundamentals, but expensive, so wait for better entry if buying.
