Actually, I was counting forward (eg. thursday-->friday being 1, etc). So is there no metric that I can use to gauge the difference between the two options? Since this is a directional play, wouldn't the implied vol. remain constant for both premiums? If so, I imagine only the theta will be...

Some enlightenment on this esoteric subject matter would be appreciated. Ok, so here's my dilemma based on these facts: 1) I want to indulge myself by buying the SPY call tomorrow. 2) My holding period is exactly 3 days. 3) The premium for the weekly options is cheaper than the...

BLS at least has some unforeseen undulation that captures the mood of 9.6% of the population who are out of work (I know, that figure is probably cooked up by the government). ADP projects nothing but a rosy scenario as if all the private employers are on a hiring spree. You can take this crap...

Uncle Sam, with the help of Bernanke and Geithner, created investment funds to target toxic securities (aka "troubled asset"), such as mortgage-backed securities where Treasury, in most cases, contributes $1 for every $1 spent by the private sector. In addition, Uncle Sam created a Disposition...

No doubt, the "voters" are equally culpable and most of these gullible voters lost their house as a result of their stupidity. But what about the fatcat executives on Wall Street who structured the massive CDOs or the rating agencies that colluded with them? Not only did they get to keep their...

I guess you didn't get this memo (err, the video). :p I'm not sure the guy is being literal or just being cheeky. This whole damn stock market crap is one giant ponzi scheme. <object width="480" height="385"><param name="movie"...

BTW if you use your machine solely for trading, I suggest you check the TCP/UDP ports and open only those that are used to access your broker. Also shut down all the nonessential services unrelated to running your trading platform, which might leave your system vulnerable.

Cascading two or more NAT routers would offer more security, but unless the trading terminal is completely segregated from other peer machines on the network, it's still hack-prone.

Although this is a popular notion, you neglect to understand that you don't need to surf the internet nor must you open an email attachment to get infected. Hooking up to a modem, which you must do in order to trade, is in itself enough to become susceptible to scanner attacks and other...

Unfortunately many virus and trojans (at least those that are well scripted) run in a "stealth" mode that will not show up in the task manager.

The best way to catch trojans and keyloggers is by installing a sniffer like ethereal (free) or Iris (one of the best but expensive) and monitor the traffic for any backdoor connections. Otherwise, you'll just need to reformat your hard drive. Be that as it may, I encourage you to download...

And yet the market kept heading higher and higher and higher, which indicates that it wasn't ordinary Joe Sixpacks of the world that were buying at those lofty levels but money managers who didn't want to miss out on the action. So it's better in my opinion to gauge the moves made by these big...

Just curious. What would happen to gold price if the greenback should lose its reserve currency status as it's currently being suggested from various quarters around the globe?

Lately, I've been thinking a lot about the opposite of naked short-selling: naked buying. It's easy to point out that you can't sell more than the outstanding shares in circulation. But the same logic doesn't seem to apply when it comes to buying. Suppose that XYZ issued 100,000 shares to the...

What happens should you get a monster U-turn the following day where you initially find yourself in-the-money but end the day as a loser?
