I asked this same question b4 but abit different from yours. My version: "Which are the SGX-listed companies most negatively affected by the all time low of BDI yet their share prices did not collapse and the uptrend remains intact, instead." Normally buying uptrend stocks have better / higher chances to make good profits than buying downtrend stocks because you're trading with the major trend of the stock, not against it.
Bro Zuolun thank you so much for so many useful links. So gloomy landscape in the shipping related business. After reading the links I took profit on NOL. It has gone up about 10% in the last few days. As you say before 见好就收 "quit while you are ahead"
