A special category of balanced, or asset-allocation, mutual fund in which the proportional representation of an asset class in a fund's portfolio is automatically adjusted during the course of the fund's time horizon. The automatic portfolio adjustment run from a position of higher risk to one of lower risk as the investor ages and/or nears retirement. Also referred to as "age-based funds". Proponents of life-cycle funds cite the convenience to investors of putting their investing activities on autopilot through the use of just one fund, which is managed for them. On the other hand, critics of these funds say that their "one size fits all" approach is suspect. For investors who don't want to take responsibility for their retirement investing, a life-cycle fund may be appropriate. However, for those who want to take the time and make the effort to direct the management of their investments, life-cycle funds should be avoided.

An annual list of the 500 largest companies in the United States as compiled by FORTUNE magazine. The list is put together using the most recent figures for revenue and includes both public and private companies with publicly available revenue data. Exxon Mobil, Walmart, General Electric and Chevron have vied for the top spots on the list in recent years. To be a Fortune 500 company is widely considered to be a mark of prestige. The collective performance of the Fortune 500 companies may be seen as one indicator of the country’s overall economic performance. For example, in the midst of the 2008 recession, the Fortune 500 companies’ collective 335% increase in earnings in 2009 was viewed as a possible sign of economic recovery. Companies' addition to and subtraction from the list also say something about the overall economy; for example, homebuilders dropped off the list after the housing market bubble burst.
A calculated adjustment to a country's official exchange rate relative to a chosen baseline. The baseline can be anything from wage rates to the price of gold to a foreign currency. In a fixed exchange rate regime, only a decision by a country's government (i.e. central bank) can alter the official value of the currency. Contrast to "devaluation". |||For example, suppose a government has set 10 units of its currency equal to one U.S. dollar. To revalue, the government might change the rate to five units per dollar. This would result in that currency being twice as expensive to people buying that currency with U.S. dollars than previously and the U.S. dollar costing half as much to those buying it with foreign currency. Before the Chinese government revalued the yuan, it was pegged to the U.S. dollar. It is now pegged to a basket of world currencies.
什么是股票破位 一般而言，股票破位是针对其技术走势而言，又可称之为技术破位。所谓技术破位，即股价或股指跌破重要技术支撑位，此前趋势发生逆转，开始进入新的相反方向趋势运行的情况。 目录 1股票破位的情形种类 2股票破位的真假判定 3股票破位后的对策 股票破位的情形种类 常见的股票破位常有三种情形：技术形态破位、均线支撑破位、技术指标破位。 一、技术形态破位 技术形态即股票技术分析理论中各种分析形态，其技术位包括长期趋势支撑线(上升趋势低点的连线)，颈线位(多重顶、头肩顶、双重顶等的颈线位)，箱体或三角形形态的底边线等。若股价跌破以上重要技术位则称之为技术形态破位。 二、均线支撑破位 均线系统作为技术分析中很重要的一种参考，其分析意义重大。如股价跌破均线，一般意味着前期趋势将有效逆转，后续调整概率较大。对于均线系统的破位，应区别对待。不同投资者的投资周期各有不同，有的定位于短线操作，有的偏重于中长线，则其选用的均线即各有长短。对于短线投资者，一般应选用5,10日均线，一旦发生均线破位，则后市短期将进入调整；中线而言，一般选用60日线作为参考，若此均线破位，意味着波段高点已现，宜中线出局；长线投资者则一般选用半年线(120日线)或年线(250日线)，此类均线一旦发生破位，则牛熊已发生逆转，应长线离场了。 三、技术指标破位 技术指标是股票技术分析常用工具，其破位对股价运行变化影响也很重大。技术指标的破位常见的有高位死叉，指标支撑位破位等。如KDJ、MACD等指标出现死叉，SAR绿柱的出现，一般也对应着股价的破位趋势。相对而言，KDJ偏于短线，其运用较为复杂，高位也常发生反复钝化，死叉、金叉不断的情况，对此投资者应区别对待；而MACD相对偏重中长线，其高位死叉指导意义较大，一般对应着股价的一段中级调整。 此外，一个特殊的例子即BOLL指标的中轨破位。BOLL指标中轨是个较为重要的参考位置，中轨之上一般代表股价运行于强势区间，破位而下则预示着股价进入弱势调整区域。因此，BOLL指标中轨的破位也是常用到的一种技术指标破位分析参考。 股票破位的真假判定 股票技术破位对于股价运行变化如此重要，则如何判定破位是否发生便显得极为重要。事实上，实战中也常发生主力操纵股价，以故意打破重要支撑位制造假破位来达到震仓等目的的情形出现。那么，如何判断真假破位，股票破位的判断依据又如何? 一般来说，股价发生破位后还会出现反抽确认的情形，投资者应观察其能否在短期内重新收回支撑位上方，若不能及时收回，则可判定为有效破位。根据支撑位重要性及周期不同，观察周期亦有长短区别。对于中短期支撑位，通常以三天为观察期，如有效收回，则为假破位；长期趋势支撑位可适当延长，但也不宜超过一星期，若仍不能收回技术位上方，则可确认为真破位。 对于股票破位的真假，原则上应采取宁错勿错过的策略。股票破位后即意味着股价进入下降趋势，破位后下跌速率一般较大，如犹豫观望，则很可能错过最佳离场时机。因此，宁可判断失误，假破位后股价继续大幅上扬错失其后利润，也比股价大幅下跌后再行离场来得要好。尤其是在股价前期已大幅上升，处于相对高位后的破位，则更应采取此原则。 股票破位后的对策 股票破位意味着股价此前向上趋势发生逆转，其后进入调整周期，一旦确认是有效破位，则应立即离场出局。即便是此前已有小幅亏损，也应坚决止损。技术破位对应的一般是较大级别转向，其下跌幅度也相对较大，如不能及时止损，则很可能由浅套而变成深度套牢，陷入极为被动的境地。止损是成熟投资者必备技能，只有在有效截断亏损的前提下才能不断累积盈利而致最终的大盈。 当然，技术破位仅是股票投资分析中的技术面分析，基本面因素也应同时加以综合考虑。对于股票分析而言，仅有技术分析是远远不够的，片面的技术分析也很难得到正确的结果。只有将基本面分析、上市公司价值分析与技术面分析有效结合，方能对股价变化趋势有一正确判断，更好的对操作起到指导意义。

A list created by Fortune magazine detailing the 1,000 largest companies in the United States. The Fortune 1000 is based on revenues, rather than other metrics of size, such as market cap or enterprise value. Since revenues are the basis for inclusion on the list, only companies that make revenue figures publicly available are eligible for inclusion in the list. Although less widely mentioned than its subset, the Fortune 500, the Fortune 1000 is still considered an important and prestigious list. Its annual publishing brings great interest in the business community because those who follow the business world are interested in which companies are included in the list along with their position relative to similar companies.
