XYZ stock is trading for $50 a share. Calls with a strike price of $50 are available for a $5 premium and expire in six months. In total, one call contract costs $500 ($5 premium x 100 shares).
The graph below shows the buyer’s profit or payoff on the call with the stock at various prices.
Because one contract represents 100 shares, for every $1 increase in the stock price above the strike price, the total value of the option increases by $100.
The breakeven point — above which the option starts to earn money, have intrinsic value or be in the money — is $55 per share. That’s the strike price of $50 plus the $5 cost of the call. When the stock trades between $50 and $55, the buyer would recoup some of the initial investment, but the option does not show a net profit.
都说地主忙,最近实在闲的难受。老婆外出一个星期,一人在家更闷。找点事干干吧。
为了有可比性,时间段都选在2011-2024
SP500
2011: 1267
2024: 5615
13 年增长: 4.43 倍
比较有代表性的在2011年买的一个SFH
2011年买入价: 15 万
首付加手续费:4 万
现在市场价:55万
净值约:45万
现金回报率(仅增值部分):11.25 倍
13年租金总纯收入约:15万
租金+净值:60 万
总现金回报率: 15倍
就是相当于买房子, leveraging
被飓风刮倒的fence,等人修。
最烦的是好房子抢不到。
如果花$5买的call, 如果这个股票第二天从$50涨到$60,那么你的call就(差不多)值$5+$10=$15。 转手卖掉,就净赚$10, 200% profit.
当然钱不是那么好赚的,弄不好,会血本无归。

念书的时候炒过option。有段时间goog 的IV特别低,股票还连涨。我就买快过期的OTM call,几乎每天call涨50%+, 变成ITM后就再roll成OTM。大概十天从一万炒到20几万吧。当时还在念书,从来没看过这么多钱,想再翻一番就可以取三番买房了。结果,最后一天股票跌了,OTM call 过期成了废纸。黄粱一梦。
这就是房产的缺点,liquidity不够。 每买(或卖)一个房子,都会有这样的问题。
用做股票的话说就是bid/ask spread过大。
我不赌买快过期的OTM call
不指望能遇到nvda,但买QQQ长期是很放心的。 这13年,增加9倍
options可以比做股票还安全。
如今我不做很risky的套路了,要是能有10%,就吃不完用不完。

我在考虑是exit 呢还是继续干,打了一辈子工,放弃工作心里有点不舒服 老板前天还拿分红来威胁我,昏,我都不知道说什么好,真想说您老人家就别拿这万把块在我面前晃了,我扣完税渣都不剩,您自己都拿着得了,不好说呀,只能默不作声
