实际情况是阅读此书确实让人收获颇丰。这本书在豆瓣网上评分9.0+/10.0,在亚马逊电商网上评分为9.4+/10.0. 尽管一度被揶揄说是被书名误导坏了的一本书。如此高的评分,也促使我们将其以致敬的方式收入到 有福经典UfqiClsc: https://ufqi.com/news/clscpage.1074.html?tit=称傲牛熊市的秘密 Stan Weinstein’s Secrets For Profiting in Bull and Bear Markets .
Stan Weinstein( 史丹·温斯坦 )不避讳地说,他的理论属于证券分析的技术派。证券技术分析的理论前提是周期论,历史会重演,太阳底下没有新鲜的事。连贯起来之前阅读涉猎的有关经济周期的相关资料,我觉得有必要对其进一步地梳理,以期形成一个关于经济周期论的自我认知小结。这已经是温习经济学内容过程中的第十篇记录了,之前一篇是 “国债与信用货币”( https://ufqi.com/blog/treasure-credit-money/ ), 其他章节的链接也分别附录于文末备查。
经济发展是有周期的,历史是会重演。太阳底下没有新鲜的事( There is no new thing under the sun. ),这句出自《圣经》的话说对了一半。对的一半刚好印证了我们的证券技术分析的历史会重演,在一个时期(周期)内,比如在太阳的这个如日中天的时段内,我们人生所经历的起起伏伏、历史朝代的更更替替、证券市场的涨涨跌跌、大海潮汐的来来回回、冬去春来寒暑易节因循不爽。 其错的一半可以用中国的古书《庄子》一句解读:夏虫不可语冰。我们还未完整地经历一个太阳周期,就说太阳底下没有新鲜的事情,显然有些偏颇了。如同夏天的虫子说,水不可能结冰一样。这里所谓夏天的虫子,是指该虫子的生命周期起于春末夏初、终于夏末秋初。
fig1.的图示显得个体人依附于某一个集体组织,集体组织/公司归属于时代的某一行业,行业又受制于政府/政权的管控,政府/政权短则数十年、长则数百年重新捣毁推倒重建轮回一次。基于这些认识,我们分析经济发展的周期,就显得容易多了。承认了经济发展是有规律地周期运动,那么作为经济的一部分,证券市场分析,则也在周期的大势之内。 fig1.的图示是单调的示意图,如果用傅里叶级数( Fourier Series )这样的数学大杀器或能更形象地描述周期发展的过程。
在Stan Weinstein里的书里,作者墩墩告诫并不断反复强调,技术分析要先看证券市场大势,并提出从森林到树木( From Forest to Tree )的选股择时方法。整体市场面是牛市还是熊市?某个行业是兴盛还是衰亡?某个个股是看空还是看多?当三者都满足时,该股票才被列入候选项,然后根据价格走势图择机买入,之后再择机卖出。 不要对抗大趋势,不在熊市时候出手,甚至不在下跌的时候持有,这大概是Stan Weinstein这本书的精髓所在,完全推翻了传统股票操作的金科玉律——低买高卖。取而代之的是Stan Weinstein推荐的呼之欲出的“高买高卖”,理论上破解了“新手死于追高,老手死于抄底”。
不幸进入这些熊市的股市或者相关行业、个股,传统的下跌回撤-20%以上的心理价位很容易跌破,如果没有这些意识而误打误撞进入,提前止损是唯一的出路。不要猜测底部,也许根本就没有底部,只有更低。回本盈利更是遥遥无期,也许最终会涨回来,只是没有人知道什么时候,三五年后作为被困被锁的资金,已经大幅折损。即便数年后回本并且盈利20%以上,计算一下年化收益率,也很难说有胜算,甚至无法跑赢实际通货膨胀率。更不幸永远涨不回来了,本金彻底灭失,这也是《聪明的投资者》告诉大家的,投资的核心是要有“安全边际( Margin of Safety )”(有福经典UfqiCsc: https://ufqi.com/news/clscpage.1069.html?tit=聪明的投资者 The intelligent investor )。

最近在读《Secret’s for Profiting in Bull and Bear Markets》这本书的原著。由于是每天几页的精读,所以读得速度很慢,留下很多思考和消化的时间。倒不是因为这本书有多么的高深或者艰涩难懂的理论,相反它是一本类似通俗读物的财经畅销书( https://ufqi.com/news/ulongpage.3377.html?tit=股票称傲牛市熊市的秘密 ),甚至读到过半会发现事情就那么些,多数是车轱辘话来回式地强调和反复。又念及这每一段文字下面都是美国华尔街股市无数散户的森森白骨,读得快了怕是阴气太重无法消散。在冬日正午的阳光下散步时去反思去揣摩去论证去质疑,渐次觉得或许这位“华尔街神童”作者(史丹·温斯坦/Stan Weinstein)真是一位好老师。由此及彼,这位老师让我回想起过去四十多年来每逢艰难困苦时,总是有天使般的老师向我施以援手,岁月悠悠这些师恩不曾随时光暗淡,反而逐渐光辉起来了——姜德臣老先生、杨光老师、杨洪波老师和尹耀廷教授。
Annotations do not directly affect program semantics, but they do affect the way programs are treated by tools and libraries, which can in turn affect the semantics of the running program. Annotations can be read from source files, class files, or reflectively at run time.
@MagicianAnnotation
public class MagicianObject {
@MagicianAnnotation(Wizard = "Harry Potter", House = "Red")
public String getString() { return null; }
}
import java.lang.annotation.Annotation;
import java.lang.reflect.AnnotatedElement;
import java.lang.reflect.Method;
public class MagicianObjectTest {
public static void main(String[] args) throws NoSuchMethodException, SecurityException {
new MagicianObject();
Class<Magician> magic = MagicianObject.class;
readAnnotationOn(magic);
Method method = magic.getMethod("getString", new Class[]{});
readAnnotationOn(method);
}
static void readAnnotationOn(AnnotatedElement element){
try{
System.out.println("\n Find annotations on " + element.getClass().getName());
Annotation[] annotations = element.getAnnotations();
for (Annotation annotation : annotations){
if (annotation instanceof MagicianAnnotation){
MagicianAnnotation mData = (MagicianAnnotation) annotation;
System.out.println("Wizard Name :" + mData.Wizard() + " , House Color :" + mData.House());
}
}
}
catch (Exception e){
e.printStackTrace();
}
}
}
该测试程序预期运行的结果大致为:
$ java MagicianObjectTest
Find annotations on java.lang.Class
Wizard Name :Reynolds , House Color :Green
Find annotations on java.lang.reflect.Method
Wizard Name :Harry Potter , House Color :Red
