[閱讀筆記] 鄭弘儀教你投資致富 (1/2)


  1. 工作不只是幫老闆口袋賺飽飽,也是為了創造屬於自己的資產,特別是要做你所愛,愛你所做,你才會做的認真,做的快樂
  2. 走的慢且堅持到底的人,才是真正走得快的人。堅持到底的道路看起來很遠,卻是達成目標最近的路
  3. 離開現在的工作崗位,必須不是意氣用事,也不是逃避問題,一定要清楚自己的方向,也要有所準備
  4. 對於一艘盲目航行的船來說,任何方向的風都是逆風 ( To a crazy ship all wind are contrary, George Herbert )
  5. 贏得信任必須走一段長路,且不斷接受檢驗
  6. 我今天所取得的成就,並不是說明我比前人高明多少,我只不過是站在前的肩膀眺望,自然看得遠一些罷了
  7. 你自己不可能是位全才,成功通常是由一些多才多藝的智者通力合作的結果
  8. 勇敢跨出第一步,不一定會成功,但是一定不會錯過機會。跨出去不見得有收穫,但不跨出去你永遠不會有機會
  9. 投資理財是「馬拉松競賽」,而非「百米衝刺」,比的是耐力而非爆發力
  10. 你不可能靠收入致富,你要藉由儲蓄本金的投資來致富
  11. 你不理財,財不理你。忽視理財就像忽視健康一樣,遲早會使你付出沈重的代價
  12. 靠薪水是不會致富的,假使你不懂投資理財,靠死薪水存錢養老,別說想老年想福,可能連基本生活費都會不夠用
  13. 你不知道你退休後會發生什麼事情,錢會貶值,利率會下降,這些都是風險
  14. 投資最大的錯誤,就是從不開始,因此也永遠無法退休。投資的越早,複利的迷利便越大
  15. 人的一生,如果被別人需要,就會產生自我價值和成就感
  16. 要考慮到未來不可預知的狀況,保留緊急時所需要的預備金。保險是一個社會風險共同承擔的制度,給社會無法預知的危險一個金錢上的保障。保險早一點買是比較划算的,但是不需要花太多錢在保險上,一般而言,意外險、醫療險、癌症險都是基本保障,但是要注意「住院費用」與「門診費用」的給付是否完整
  17. 近年來所盛行的儲蓄行或投資行保險需視你個人情況而定,因為每個月要繳的費用很高,而且投資型保單有一定的保險存款準備,只有一小部分能使用於投資,且獲利空間並不大
  18. 投資賺錢要行有餘力,特別要把握零負債的原則
  19. 外匯投資在台灣的可操作空間很小,沒有什麼利潤可言。因為台灣政府對外匯的正式,是一個用穩定外匯,讓商人能夠必顯得工具,中央銀行不希望外商銀行賺取外匯波動的錢,原因在於台灣是出口貿易導向型的國家。因此,外匯對於像台灣以貿易為導向的國家而言,是不容易有利潤的
  20. 債券雖然風險很小,有穩定的獲利空間,但是報酬率很低,通常在 2 ~ 5 % 左右。在不景氣的時候,隨著央行利率調降 17 次,市場利率幾乎要降到 0,代表買債券是賺錢的。但是當景氣反轉時,債券市場就會變得無利可圖
  21. 在股市群眾裡,人們的智慧不會增加,反而是愚笨程度會越積越高,而且群眾的理性程度等同於八、九歲的孩童
  22. 大起大落的每股盈餘不適合長線投資,比方說今年每股盈餘賺五元,明年卻賠了三元,此時,配了股票不但沒有填權,股價還越走越低
  23. 檢查所投資的公司是否有揭露董監酬勞和員工分紅所佔的盈餘比率,若是分紅比率過高,就要計算所買的股價是否合理
  24. 股市聽信明牌是最危險的事情,任何旁門左道的「明牌」到了散戶手中就是「廢牌」,你聽到媒體講的「新聞」其實都已經是「舊聞」
  25. 「貨幣供給」是指整個社會在某一時間所存在的貨幣數量。貨幣供給額的增減能夠反應經濟市場資金狀況的好或壞。大致來說,影響貨幣供給額的因素包含貿易逆差、經濟成長率、貨幣流通速度和物價水準等。當貿易呈現順差、經濟不斷成長、貨幣流通速度快及物價水準高,貨幣供給額就會增加,反之則減少。貨幣供給額增加快速,代表這個國家在創造金錢的能力很強;若貨幣供給額增加減速,代表這個國家掙錢能力縮水,錢越來越難賺

@Data
public class Dbm506rVo implements Serializable {
    /**
     * 
     */
    private static final long serialVersionUID = 1L;
    /** 年度 */
    private int year = 0;
    private String staYear = "";
    private BigDecimal gdp = BigDecimal.ZERO;
    private BigDecimal capitalAmount = BigDecimal.ZERO;
    private BigDecimal interestAmount = BigDecimal.ZERO;
    private BigDecimal yearExpend = BigDecimal.ZERO;
    private BigDecimal ttlAmt = BigDecimal.ZERO;
    private BigDecimal percentage1 = BigDecimal.ZERO;
    private BigDecimal percentage2 = BigDecimal.ZERO;
}


How-to
Set net.sf.jasperreports.export.xls.detect.cell.type to true (the default value is false) in this jrxml file.

Quote from document: Property whose value is used as default state of the IS_DETECT_CELL_TYPE export flag. Specifies whether the exporter should take into consideration the type of the original text field expressions and set the cell types and values accordingly.
