大部分人都认为要想赚钱,选股成功率是最重要的,其实这是片面的认识.影响投资盈亏的因素有三点:选股成功率、盈利率、亏损率.
实践中无论用什么方法、什么方式去操盘,投资者都会面临三种情况:亏损,平手盘,盈利.笔者认为操作中那些小赚小亏的和平手盘这3种情况,都应该统计归纳为平手盘.因为长期操作下来这些微亏损与微赚的操作相加,其结果基本相当等于0. 相似文献

内部人(insider)增持公司股票,通常会被看作是一个积极的信号,表明公司当前的投资价值和经营前景被内部人看好。由于市场相信内部人掌握的信息总是充分的,是最了解情况的,所以一部分投资者认为这是一条选股的捷径,喜欢跟着内部人走。 相似文献

在投资领域,逆势而为是一大忌,因为大趋势正是绝大多数品种一致行动的结果,从概率上看,投资者如果选股,选中符合趋势方向的大多数品种是大概率事件,因此,逆势而为存在较大风险,对于大多数投资者而言是不应采取的投资措施。从稳健的角度来说,始终坚持顺势而为,是股市生存是必备法则。但是,既然趋势是绝大多数品种的一致行动,那么必然有一小部分品种是不跟随大趋势的。 相似文献

本周市场继续创出新低,使得投资者根据以往经验而作出的"国庆节前出现反弹行情"预期落空。市场熊态毕现,成交量亦萎靡不振。在过去的一段时间,我们提出"在市场低迷的背景下,选股策略一定要考虑具有较强安全边际"。从实际走势来看,这种思路在低迷行情下未必 相似文献

Many college freshmen arrive woefully unprepared to do college work, and as disadvantaged populations continue to grow, the share of the American work force that has made it through college is expected to plummet. Many experts blame that educational failure not just on high schools but also on colleges. School & College, a special report by The Chronicle, looks at efforts to fix the system. What reforms would better prepare students for college? What should schools and colleges be doing differently? How should state and federal officials help? 相似文献

There are numbers of crossroads on our long and unpredictable life journey where we totally have no idea about which direction to choose. No matter what our decision is, we should not turn back, but face the music and go ahead instead. I am this kind of girl who always does try without regretting, one example is how I dealt with my love. 相似文献

Sister Carrie is one of the most controversial characters in American literature.Thought as a "fallen woman" firstly,she was defined as a "new woman" by some critics later. However, by digging into the motivaton behind the whole process of Carrie's "success", the relationship between Carrie and her creator (the author), the social conditions of then American, it can be found that Carrie has never been free-standing on her thought and she has never found her real-sdf even after becoming a famous actress. In a society dominated by mass consumerism Carrie is only an adherent of her own desires. She also is a representative of all those country girls flooded into cities, a symbol and a sacrifice of the urbanization of America in a time countryside was overcome by cities. 相似文献

During interview with English majors, it was found that a majority of students expressed disappointment with their experience of English literature classes. Students' dislike of learning English literature appears to be the major problem of teaching English literature in China. Reader response approach is a good way to solve this problem. In this paper, I explain the rationale behind the reader response approach, such as its origin, definition, features, assumptions, and strategies. Then I illustrate how reader response approach works as a teaching strategy by presenting several teaching models. At last I evaluate its usefuiness for teachers and present the advantages of reader response approach in Chinese context. 相似文献
