我觉得价值投资，成长投资，逆向投资，基本原理都一样。就是相信股票价格长期来看
会反应股票价值。短期来看，市场常常会出错，导致价格偏离价值，但长期来看，价格
最终会反应价值。你所要做的，就是找到市场出错的时候，找到价格<股票的价值由未来的业绩决定。因为是未来的业绩，所以不要过分依赖静态市盈率。估
算价值主要靠基本分析，包括三个方面：宏观经济，行业和公司。
传统上的价值投资是格雷厄姆的价值投资，判断价值主要是净资产，和市盈率(PB 和PE
)。彼得林奇的成长投资主要依据的是PEG。在他的作品中，经常提到“当你看到一个公
司的成长率为25%，而市盈率只有20甚至15，赶快买入”。逆向投资那些咸鱼翻身型，
周期型股票和萧条行业中所谓的荒漠之花，关键也在于对公司未来业绩的把握。巴菲特
的股权债券投资，按他自己说法的就是85%的价值投资+15%的成长投资。
价值投资的难点就是预测公司未来的业绩，这个对大多数散户来讲难度是极大的。所以
，散户想要赚钱，技术分析必不可少。
即使是投资，也必须依靠技术分析来决定买入点和卖出点。在向下的趋势中抄底是非常
危险的事。巴菲特在08年逆市抄底高盛

最近一直在琢磨一个问题，实验还没开始做，和大家聊一下，看看大家的意见
现在往一些微米尺度的小孔里填东西或者长出尺寸空间限定的晶体
并不稀奇，比如做一个前体化合物，或者非晶态前体，然后滴到
那个有孔模板上去，然后诱发一下，比如加热等，让它转化成单晶形态
我现在想这个方法或者说思路是不是适合纳米尺度的孔，如10-20nm
就是说滴上去的东西，是不是会由于重力作用而沉降到孔里。那么小的
尺寸是否会因为比较大的表面张力而变得不沉降？
求教一些有经验的朋友，多谢了

"巴菲特在08年逆市抄底高盛，不能算很成功，抄底之后还有30%的跌幅。"
巴菲特买的是年利息10%的可转换债，而且优先级很高。哪怕高盛跌90%，只要没有破产
，他都赚。如果涨了，他可以在105的价格上买入。巴菲特买的时刻，连moneny markey
都有亏钱的。如果考虑risk adjusted return, 我几乎没有看到比那更好的投资。

呵呵，我也想说这个来着，包括中投的优先股，定的9%-10%的分红，没什么不好的，
本来优先股就没有投票权，但是国内似乎对固定分红的优先股很有意见，感觉伤害

楼主写的很好，是mitbbs中少有的明白人，炒股要参考技术指标，但是纯靠技术指标悬

NL拿身份比高校postdoc容易。但前景并不比高校postdoc好很多，钱多些，转成
staff的机会要看运气和专业，有些熬7-8年也还是postdoc，有些1-2年老板没funding
了，也是一样要走人。还有，NL postdoc去做faculty的机会不如高校postdoc多，
paper发的也不会多。基本上，NL postdoc介于industry postdoc 和academic postdoc
之间。
好处是，工作比较轻松，钱多，压力比较小。如果比较layback的人可以考虑。
