檢驗種收律

如果我們以“種收律”來看待我們必賺的股票買賣，每到年終時，我們可以統計一年內，譬如2014年，那個股票FB：

1. 一共種了: 82次

2. 一共收成了(包括以前種了，今年才收割的) : 88次

3. 已經成熟，還未收割的有: 11次

4. 還未成熟的有: 0次

5. 每次的平均收穫量有: $248,276/88 = $2,821

6. 平均收割期是: 52天

7. 大概平均一次收割：475股；成本：$61*475 = $28,975

8. 在6天以內就收割的有：38次；共賺了：$37,722 ；平均收穫量只有: $993

譬如2014年下半年才開始的新品種NUGT：

1. 一共種了: 115次

2. 一共收成了: 68次

3. 已經成熟，還未收割的有: 8次

4. 還未成熟的有: 39次

5. 每次的平均收穫量有: $76,278/68 = $1,122

6. 平均收割期是: 3天

7. 大概平均一次收割：800股；成本：$15,800

有了這些統計以後，大概還可以預算新年度要如何添新苗？要不要增加平均收穫量？那個股票品種的成本低，收穫量高？

假設FB 的平均收割期縮短成3天，你們猜會出現甚麼現象?
假設NUGT 的平均收割期放大成52天，你們猜會出現甚麼現象?

有人認為：幹麼那麼煩？揀錢就好了...
我告訴妳：到時候別人揀得到，妳就揀不到。

有人喜歡賺錢，卻不喜歡知道賺錢的方法。
有人要上天堂，卻不喜歡認識神。
