回复3#菠萝仔哦那皇冠制造机呢什么意思?都说三蛋是。

From my understanding, I give some explanations as below:-

1)The Altman bankruptcy score；
- one method Altman developed to determine the bankruptcy possibility of one company.
- as it uses several quantitative factors, it's very pupular in invesment fields.
2) book-to-market ratio；
-the book value of an asset /market value of an asset;
-Asset can be an enterprise or a financial asset;
In accounting, lots of Assets/Liabilities are recorded at historical cost. This ratio gives us more info.

3) Market beta；

4) the FF three factor model；
-Fama French Model
-an asset pricing model
-Similar to CAPM, but using more factors

5) AMRT（缩写，请教啥意思）；
Don't know! Never met it before
6) dividend yield；
-Holding period yield= (purchase price+dividends-selling price)/purchase price
-Dividends yield=dividends/purchase price
-purchase price-selling price=capital gains

7) the Herfindahl index of sales；
- also known as HHI
- It mainly measures the industry concentration ratio, somewhat like four-enterprise concentration ratio
- Calculation= Square(market share of firm 1)+ Square(market share of firm 2)+....+Square(market share of firm N)
-Comments: as all firms in the industry are under consideration, it reflects the industry charactristics  better than 4-enterprise concentration ratio.

8) SIC 3-digit；
-It should be US's industry classification standard if my memory serves me well.
9) market cap；
-Market capitalization=market price of the share×Number of outstanding stocks

10) payout yield
it should be similar to dividens yield, I think.
