《How To Know When To Sell An Overvalued Stock | FAST Graphs》
RTX 估值显著偏高；尽管盈利有增长潜力，均值回归可能导致 14% 的年化亏损。
接下来的一只是原来的 Rathon RTX。这是 Rathon 和 United Technologies 的合并。而在这里，这只股票相对于其历史常态变得疯狂高估，相对于预测也变得疯狂高估。
所以你给盈利一个超过10%增长的机会，而如果且当这只股票均值回归时，你可能损失14%的年化回报。而且再一次，那段时间并不是确定的。
Next one here would be the old Rathon RTX. This is a combination of Rathon and United Technologies. And here the stock is getting crazy overvalued relative to its historical norms and it's crazy overvalued relative to forecasting. So you give a chance of earnings to grow at over 10% and you could lose 14% annualized if and when the stock reverts to the mean. And again that period of time is not determinal.
