in my opinion, a low ROE does not mean a weak business and a high ROE does not always mean a strong one. For example Im taking UCL case (uCloudlink). Their ROE 8.7%, not really impressive but their fundamentals looks very interesting. Their EPS grew 85% over the past year, net income expanded 60% in five years and the stock up to almost 50% in 12 months. According to these numbers, I can see that their growth is outpacing than what their ROE reflects. Recently, their price drop a bit but when we looking into a long term and as Benjamin Graham said: "In the short run, the market is a voting machine but in the long run, it is a weighing machine". This shows that ROE didnt capture the full earnings of a stock.
