我美股賠最慘的淡水河谷曾跌了90%，
它是巴西的鐵礦砂廠，世界最大。
巴西股跟我八字不合，2013年就買了VALE，
當時美國景氣正要復甦，QE尚未退場，
此時買原料股景氣循環股最適當了，買在起漲點。
不料後來美國景氣復甦了，其它國家卻無起色，
這種復甦不同調的現象過去罕見，
鐵礦砂價格甚至創歷史新低，
加上巴西幣貶值5成，
VALE股價跌了90%。
I suffered the biggest loss in VALE, which dropped by 90%. VALE is an iron ore company in Brazil and is the world's largest. Brazilian stocks do not suit me, but I bought VALE in 2013. At that time, the US economy was on the verge of recovery, and the Fed had stopped quantitative easing. Therefore, it was the best time to buy raw material stocks for cyclical growth. Unexpectedly, while the US economy later recovered, other countries did not improve. This kind of uneven recovery was rare in the past, and the price of iron ore even hit a record low. Furthermore, with the Brazilian currency depreciating by 50%, VALE's shares dropped by 90%.
仔細反省，VALE為景氣循環股，
股價波動太激烈令人承受不起，
改買公用事業股就穩當了。
同學力薦AESAY，巴西水利發電廠，
水利發電不受燃料價格影響。
買了之後卻遇百年大乾旱，股價跌了50%。
想說忍耐一下老天總是會下雨，
果然下雨了，股價反彈在望，
2016年2月股價最低時公司卻宣布下市，
強制把股票賣在最低點。
玩家還想繼續玩，莊家卻把籌碼收走了。
After careful consideration, I realized that VALE is a highly cyclical stock, with a stock price that fluctuates greatly. In contrast, it is safer to invest in public utility stocks. One student strongly recommended AES Tiete SA (AESAY), a hydroelectric power plant in Brazil, which is not affected by fuel prices. However, after I bought it, the company experienced a hundred-year drought, causing its stock price to fall by 50%. But eventually, it rained and the stock price rebounded. Unfortunately, in February 2016, when the stock price was at its lowest, the company announced its delisting, forcing me to sell the stock at the lowest price. It's like a player wanting to continue playing, but the dealer takes away their chips.
2016年VALE強勁強彈，股價漲了4倍，
是我手中持股有史以來一年內漲最多的，
而我仍賠了50%，
預計總共要反彈9倍，才會解套，
淡水河谷成了我的永恆持股。
In 2016, VALE had a strong rebound, and its stock price rose 4 times. It was the highest increase in my holdings within a year in history, yet I still lost 50%. It is estimated that it will require a total of 9 rebounds to mitigate my loss. VALE has become my eternal holding.
