W********m 发帖数: 7793 | 1 昨天的MRK, 今天的 TOL。 涨得蝌蚪我都不好意思了。
来点野鸡中的战斗机的FA:
昨天底点在捞了点 TOL, 在蝌蚪19$和 13.5$ 分别走掉 TOL和KBH后(顿足捶胸)再
次上了builder. 蝌蚪觉得builder 还有得涨, 特别是earning 不错,PE比较低的DHI
, TOL 和 LEN,还在赔钱的 KBH, HOV, BZH这类泡沫不少,风险有点大,蝌蚪胆子
小就不碰了。 哥住在新泽西最便宜的烂区, 上礼拜有新社区开张,房子还没建, 只
有两个model 屋。 第一天开卖, 26个SFH一天抢光。 所以蝌蚪大胆推测这波房市泡
沫才开始, builder 每一次pull back 都是买入的机会。
MRK 最近应该有些 Catalyst, 不解释。。。
股神,请指出蝌蚪分析的不足之处。。。 |

Prokaryotic genomics revealed the wide spread of HGT in the prokaryotic

that HGT spares virtually no genes

AIR long 70%
Pick#2, Long/Short,权重比,LMT(opt) 如:Long,50%:
TOL short 30%
选股理由:
1. AIR在这期间报ER, 感觉会不错,赌一下,从TA上看,刚从trendline上弹起来,还
有涨的空间。
2. TOL走出一个大三角,就快走完了,向上向下在pattern上都合理,在2-3个月里变化

s****h 发帖数: 921 | 18 min f(x) 的收敛标准如何选择?
f(x)是正的.x是一个4维向量.
一个选择是对f(x)选择一个tol,比如f(x)<1%就停止收敛.
还有一个选择是针对向量x选择一个tol,比如 max(x./abs(x))<1%就停止收敛.
哪个更合适?
我的算法运行时,f(x)下降到1%左右就减不下去了.
不过我发现向量x的值仍然变化很大,向量x中的某些元素的变化大于10%.
还有,我在收敛的时候为防止x的变化过快,对每次迭代的x的变化幅度设置了10%的上限.
这个对收敛性能应该是有帮助吧? |
