如果90天内不能重新买入VSMAX。
另外，我卖掉的TAX和不卖的DISTRIBUTION TAX都是short term tax rate吗？

发帖数: 1230 | 33 去年10月开始，在Schwab开设了一个Managed Account，同时在Fidelity开了普通的
brokerage account.
Schwab的管理型账户选择了Aggressive/High Risk Tolarance的投资组合，大约有20支
ETF组成。这半年内只有极其个别的变动，而且都是小幅度调整。半年后的（未扣管理
费前的）收益率是4.96%，管理费是投资额的1%，那么实际收益率大概是3.96%。
同样的时间区间内，Fidelity的账户内只买了一只大盘指数基金（IVV），买入后就一
直放着。半年后的收益率是7.75%。
这半年大盘一直走高，且在同样的时间和市场，Schwab的管理型账户，特别是
Aggressive/High Risk Tolarance的投资组合难道不应该比大盘指数表现更好吗（当时
开户时，Schwab给出的benchmark也是S&P 500）？而实际收益率仅有简单的买IVV放着
的收益率的一半左右。
去问Schwab，他们的解释是他们的投资组合很多样化，未来“可能”会有比大盘表现更

的smaller存的是每一个A[i]的upperbound，但是每次查找的过程都是顺着smaller里面
存的下标往前找，直到找到第一个A[index]可以满足A[i] > A[indx]，这是线性不是常

发帖数: 499 | 44 谈几句equities大盘。
要精确地判断大盘是很困难的。
所以我不想说大盘马上要跌，或者大盘还要继续升。
我只是从概率上讲，大盘已经离短期顶部不远了。
我的主要依据是：
Fear & Greed Index
http://money.cnn.com/data/fear-and-greed/
现在这个index是92.以前通常顶部时的数据是80多。
从最底部的那个图，可以看到92这个数据，是3年多来最高值。换句话说，现在的
bullish情绪，是3年多来的最高值。
再看昨天是89.所以如果像今天这种升幅再来2，3天，这个indx就要冲到100了。100是
不可能的。我见过的最悲观的时候的数据是3，那是在15年8月的大跌。
所以从概率上说，大盘继续向上冲超过2，3天的可能不大。
RUT 5天RSI现在是98多。这个我也是第一次见到这么高的5-day RSI. |

假设你读入的数据对象名为myData。

n=0
for(ii in unique(myData$pos))
