Its funny how people will take a source blindly without checking it. I happen to concentrate on the area of material sciences and the family of the aformentioned superconductors were discovered by Japanese researchers. The Chinese merely found another compound of that family. The "professors"...

NetShare is gone from iphone app stores. Apparently it's been banned.

Not necessarily. If you are fully automated (like I am) you'd want to forward test a system in a sim account before throwing in real money. For a discrectionary trader though, it's much better to start with a small real account than a simulated one.

Ignorance at its best.

I, unfortunately, came from a Chinese university and I, fortunately, earned a PhD here in the US. The fact that so many Chinese students come here for PhD degrees does not mean the Chinese higher education system is good. It means the opposite. Original thinking is constantly suppressed in...

Most of the linear reg packages in TA softwares are standard ordinary least square regressions. Technically they are not correct since the standard error estimated will be off because you are fitting a standard OLS on time-series data which suffer from severe autocorrelation problems. You are...

The # of hours worked per week does not necessarily correlate to the output level. You would expect that the # of work hours would drop as the level of automation increases. So you would expect the developed world to get "lazier" as fields such as robotics and artificial intelligence advance.

First of all I am from China. No Chinese national has ever won a Nobel Prize in anything. The Chinese high schoolers dominate in the world math/physics/chemistry Olympiads yet none of them has ever won a Nobel Prize, ever. The "Chinese" Nobel laureates you mentioned are ALL Americans (and...

It's interesting, since their oil shares have 5? year life you would expect that the "expectation" factor would bring their correlation more in line with the 5 year CL future contracts right? Nope they don't. The correlation with 5-year futures is even lower than the (0.32) correlation with...

No the price for their shares will NOT move with the underlying at all. All they do is swapping the assets back and fourth making the NAV move with the index but the actual PRICES will go absolutely out of whack because people will price them based on whatever "expectation" they have. Just...

What I meant is _theoretically_ their shares should be arbed against CL1 futures, which is easily available and have good liquidity, but they weren't. That's probably because the interest in their ETFs were so low that MMs didn't even bother to arb those. With housing, this is even more...

I just read their prospectus. The ETF is a complete scam - there's no market for any market maker to arb their "shares" against the index which they claim to track so this "product" will not track any index and their price will go up and down randomly based on godknowswhat. Another quite...

Overall short interest on the S&P 500 stocks has been declining but we are still at historically high SI levels. We might see a final short-squeezing upthrust before the big drop. May happen this week or early next week. And given the current level of euphoria still we need a catalyst, some...

I agree with Port. While most of the other stocks' price increase is accompanied by large volume's buying, most of NILE's large volume transactions seem to be on the sell side since March 20th. This one seems to be a prime target for shorting and it has been on my radar for a while now. I...

Too dangerous to put on either long or short now. I'm calling it a day.
