Austin Lieberman maintains a bearish outlook on Palantir ($PLTR), characterizing it as a "bubble stock" that remains overvalued despite a recent 30% price decline. He expresses interest in owning the asset only at a price target near $80, citing concerns that even with high revenue growth of 45% per year, the stock could yield negative returns by FY28 at a P/S ratio of 18. Technical charts from FAST Graphs support this sentiment, projecting a potential 58% decline over the next two years even if the company meets aggressive growth estimates.
