PIMCO一直做Junk Bond 不能和TLT相提并论
TLT是股票portfolio的缓冲 目前长期收益为负 但是大小调整 包括熊市 TLT不降反
升 所以很多人把它放在portfolio里 目的是保证自己在大熊市面前 不会panic 割
肉 甚至失去信心退市 08年以后 很多人好几年都没进股市 错过了大牛市 就这一
点就值每年损失几个百分点收益保持30% TLT在portfolio里 大多数人面对大调整和熊
市 都会panic 割肉 以至灰心退市
IEF是TLT的缩小版本 涨幅跌幅总体除以2-3吧 除此以外值得买的就LQD和AGG
JNK HYG 没有太大意思 如果坚信高通胀的话 可以考虑买TIP

来自主题: Stock版 - 该买TLT的call了
市场如果大跌 TLT会大涨
但是现在大家对于长期国债有情绪上的偏见
你看看TLT和TLH 前者相对后者有很大的折价
市场的偏见会持续多久?不好说
TA上看 TLT可能去一趟110
赌市场跌的话 可能IEF更稳健一些

Bond tends to be going to low as interest rate is raised. But we still need
to have some bonds in portafolio. The reason is that bonds can prevent
maximum drawdown is large and is a good hedge. Long term bond is not
influenced so much by interest rate.
Since you need the money two years later, I would recommend to buy more bond
(more than 50%) like TLT or IEF. These two bonds will raise when market is
going very bad(You can check 2008 market history).
For stock, you can just buy SPY and hold it... 阅读全帖

来自主题: Stock版 - 开户半年的交易记录
总结一下经验
1)买入时要选个相对低的价钱 可以画一条直线 大部分时段都在这个股价之上。问
题是很难买到,这是可以用OCO order 买多只股票 每只都设置比较低 设成GTC
order 只要有一个买入就取消其他的 比如买TSLA就设成190 IMAX就设成29.5 这样买到
时很大几率会赚一些
2)可以在觉得估计高的时候 可以搞一下covered call, 虽然经常会赔钱 如果
covered call 赔钱了,相应的股票一定会赚 总体是赚的 赚钱比较稳 call最好卖on
the price call得到钱多些 注意一定是觉得比较高的时候 但又觉得可能还会涨 就
可以高covered call。不到到期时,如果call赔钱,可以适当等着,高了3次covered
call只有一次赔钱。
3) 交易费用很重要 ib 和tradestation 100股 不到1刀的交易费用可以省掉好多钱。
利润不会被交易费吃太多
4) 一定要买那些自己用过的公司 或者看到身边有朋友用的公司 炒股赚钱最重要的
是不赔钱
踩坑 用过的公司不是坑的几率大写
5)P/E比较高的股票... 阅读全帖

Look at IEF and TLT in stock market crash during 2008. you will know. They
do will increase value when crash. But it seems only national bond increase,
company bond also decrease when market crash.
It is always good to hold some bond in 401k. Depending on your age, normal
suggestion is that if you are 30 years, hold 30% bond. if you are 40 years
old, then hold 40%.

驳吴主光牧师关于关于预定论的教导
宏深
基督教改革宗神学对预定论最为简洁,完整的表述,即通常所说的加尔文五点救恩论,
包括以下五点:
1.全然败坏
2.无条件拣选
3.有限救赎
4.救恩不可抗拒
5.圣徒永蒙保守
必须指出,以上五点并非加尔文本人或者某位改革宗神学家的发明,虽然加尔文本人在
基督教要义一书中对预定论有详细的讨论,他却并未将救恩神学简单地用以上五点来表
述。所谓加尔文五点乃是1618年多特会议为了驳斥阿民念异端教义而定,阿民念派人士
在多特大会上提出与上述五点截然相反的教导,并要求荷兰教会修改已有的教义标准即
海德堡要理问答和比利时信条当中关于预定论的教导来迎合阿民念主义的自由意志论。
作为对阿民念异端的回应,大会作出以上针锋相对的五点决议。从此改革宗救恩神学通
常又被简称为加尔文五点。
加尔文五点救恩论完全是严格建立在圣经的教导之上,因此以上五点成为一套严密的逻
辑体系。后人往往遗忘教会历史,误以为加尔文主义是建立在逻辑推理的基础上。事实
上,加尔文主义之所以在逻辑上如此严密,乃是因其严格遵守圣经教导,这一因果关系
绝对不可颠倒。相反,以自由意志为特征的阿民念神学才是建... 阅读全帖
