When a stock is widely loved by analysts, what does the consensus already price in?

When nearly every analyst on a name rates it a buy, the question I keep asking is what the current price already assumes. A stock can be a good company and still be a poor purchase if the expected growth is already baked into the valuation. One way to test this is to look at the implied expectations: what revenue growth or margin path does today's price require under a standard discounted cash flow setup? Then compare that to what the company has actually delivered over the last few years. If the required path is well above history, the consensus may be leaning on a surprise that has not happened yet. The contrarian angle is not "the crowd is always wrong." It is that consensus tells you what is expected, and the interesting moves often come from outcomes that differ from expectations. I am genuinely unsure how reliably this works across sectors, so I would like to hear where it breaks down for you. When a stock has near-unanimous analyst support, what do you check first to see whether the expectations are already priced in?
