Topic: Buy&Hold最近好象work了 @SF湾区华人论坛:SF湾区枫下论坛 The Rolia Forum of San Francisco

BUY&HOLD是风险大，收益大，我的观点不知对否？JNPR现在是$7.2了，BRCM $12.27. 呵呵，涨得不少呀！
我倒觉得Buy&Hold主要还是要看运气的，像我这样从来都中不了奖的人，炒炒短线还有点盼头^_^ -amber(琥珀); 2002-11-7 {136} (#843028@0)

只有在牛市中（10月份这个也可以算局部牛市了）才可以buy&hold。如果你看看那些即使在$10以上买NT的，buy&hold根本就大错特错。其实不是buy&hold不对，关键是知道什么时候buy&hold才是难点。 -wins(wins); 2002-11-7 (#843056@0)

看过一篇文章，说BUY&HOLD实际上是上市公司和“专家”们诡计，劝小股民只买不卖，把市场炒热。呵呵，有点道理。另外，想请教一下做"short"的技巧.. -amber(琥珀); 2002-11-7 {35} (#843074@0)

最保守的short 是买closed put option，优点是投入资金小，买入速度快，可以网上操作，缺点是时间期限短。如果直接short最好留有足够的资金，否则被强行平仓很惨的。 -wins(wins); 2002-11-7 (#843090@0)

option有四种open/close call option, open/close put option.简单来说，如果你买了100张csco的close put option@$12，如果csco将来跌到$8.你可以在$8买入10000股csco,然后execut你的put option,券商会保证将你的csco按$12卖出，这样你每股就赚了差价$4.
当然你也可以不买csco的股票，直接将put option卖出，这时put option也应该涨了数倍了。
看完以下的介绍你就会大致清楚了

谢谢！我好好学习学习，再和你探讨^_^ -amber(琥珀); 2002-11-7 (#843187@0)
open 和close的有什么区别呢? 另, 在toronto哪家broker有online option trade ? 你用啥软件check realtime option quotes ? Thanks ! -falcon(令狐葱); 2002-11-7 (#843201@0)

No. open意味着买空或者卖空。出售close的option的券商或个人手头上是持有对应数量的股票的。 -wins(wins); 2002-11-7 (#843248@0)

But option and stock are traded at different exchange, how do you know whether it's open/close ? or if I long 100 csco, and short 200 csco put, then I sell my 100 csco put, is that open or close ? -falcon(令狐葱); 2002-11-7 (#843299@0)
“手头上是持有对应数量的股票”好象是指sell covered call 或有sell covered put 中的covered的概念吧。for example:

I hold PMCS 1000 shares, so I can sell 10 covered calls against my holdings. On the other hand, you can sell call or put without any underlying shares, those are called naked call or naked put. They are too risky.

Open, may simply mean to open a position.
Close, may simply mean to close a position.

Really confusion, I may be wrong. The option that I play are simple ones:
buy call
buy put
sell covered call
sell covered put -maple2000(枫叶飘); 2002-11-8 {456} (#843426@0)

Unless you have millions of excess money, never buy and hold as an individual investor. The ones control the stock market are institutions. They can easily drive the market down or up by any excuse.Good news can be interpreted as bad or the other way round. It all depends on their needs. Merrill Lynch alone holds about 15% of total Wall Street investment. Those big guys often bundle together, upgrade or downgrade a stock based on their interests. Small investors are being trapped once and again. Buy and sell often may be best for us at least in the current market situation. -oldie(OLDSTER); 2002-11-8 {387} (#843500@0)
