It looks like Siemens wants to become another General Electric. The problem is that the financial side of GE is what's killing that company. (The only reason GE didn't go into bankruptcy is because our government propped it up.)

An interesting read, especially the part about "quote stuffing" -- where some HFT systems send huge numbers of quotes in a short period time, the only apparent purpose being to overwhelm the computational capacity of other HFT systems.

In this country millionaires promote capitalism and billionaires promote socialism.

Obviously this woman has the intellectual qualifications to be a Democrat.

The Democrats want to give 20 million illegal aliens amnesty, knowing that 80% of them will then vote for Democrats. Not enough Americans will vote for Democrats so they want to replace us with people who will. Obama in particular has no desire at all to see immigration law enforced. His...

So 8 years later strategic defaulters can do it all over again? Why give them a second chance? We lost enough money on them the first time. And I say "we", because courtesy of our criminal government we are all guaranteeing Fannie Mae's debt with our tax dollars.

It was a gimmick and it got old.

The fact that he was asking your opinion suggests to me that he has no chance of consistently making 30% a year and anybody who invests in his fund is a fool. To start a hedge fund you should have a track record of at least a few years of real trades where you know what your edge is and can...

Methinks Scataphagos does not actually trade for a living, and probably not even as a hobby. 27% per week? Consistently? Thus turning an initial $10,000 into $960,000,000 in 48 weeks? No trader has ever done that.

Halving a $1.4 trillion deficit means having a deficit of "only" $700 billion -- 50% higher than it was during the pre-crash Bush years. (And those deficits were bad enough.) So even if this reduction is achieved I will be less than impressed.

Just what is greedy about insisting that if a giant corporation causes billions of dollars of damage that it must pay billions of dollars of compensation? I favor capitalism, but that means that if you create billions of dollars of value you get to keep billions, and if you cause billions of...

Options are a zero sum game. Therefore, if options are priced efficiently, and if the pricing assumptions in your "probability calculator" are the same as those used to price the options, then with no bid/ask spread and no commissions you would expect *every* option trade when opened to have an...

I do hope you're joking. The crisis was caused by too much debt and speculation. So I hope you're not serious that you want to tax prudence and saving for a rainy day.

It is of course a red flag any time an options advisory service ignores the margin requirement when computing "gains". Otherwise I'd get infinite percentage gains every time I sell a naked put.

There are three things the author failed to consider. The first is that people believe what they want to believe, unless reality forces the truth down their throats. It is highly unpleasant to think that human caused global warming is real because that would mean that certain aspects of your...

While I don't know of any rigorous definition of what makes an option trade an "income trade", in practice they tend to be theta positive trades where the money is made primarily on the time decay. So calendar spreads are long the long dated option, short the short dated option. Iron condors...

Actually many option traders have come to the opposite conclusion -- the only way they can consistently make money is to do income trades that bring in maybe 5% a month. Calendar spreads, iron condors, and the like.

Ron Paul is a good man but he will never get the Republican nomination because the Republicans who vote in the primaries and who run the party are stupid fools who think that unending war in the Middle East is crucial for our country. They will do nothing but nominate Bush clones, year after...

The Greeks are linear, so just add 'em up. If you have a bull call spread where the long option has theta -0.07 and the short option has theta +0.03 then the net theta is -0.04.

Green pieces of paper have even less value. So if the value of gold is a collective hallucination than that is even more true for the value of the dollar, yen, or euro.
