Excellent commentary about FusionIQ in this weekend’s Barron’s:
Separating potential winners — and losers — from the herd.
MARKETS LIKE THIS DEMAND A CLOSER LOOK before you leap. Fortunately, there are plenty of online resources to guide you.
Some are oriented toward fundamental analysis, some toward technical signals, and some, like FusionIQ (www.fusioniqrank.com), incorporate both, and more.
A research and money-management firm, FusionIQ has just made its quantitative stock- and sector-screening system available to retail investors. A $40 monthly subscription buys you access to the kind of expensive, computer-based screening that quantitatively oriented investors, or “quants,” enjoy.
FusionIQ subscribes to the Pareto Principle, which states that 20% of stocks will be responsible for 80% of future gains. Its huge nightly data crunch separates potential winners (and losers) from the herd. Being invested across multiple sectors for the “long term” may qualify as diversification, but it doesn’t yield excess returns, explains CEO and longtime market analyst Barry Ritholtz.
“Buy-and-hold has been a jumbo money-loser this year,” argues Ritholtz, the subject of a recent Barron’sQ&A (“A Leading Bear Turns Bullish, Sort Of,” Dec. 8). “You can’t just sit around and say, ‘Bear Stearns and AIG are great companies, and I’m a long-term investor.’ ”
FUSIONIQ’S MODELS blend fundamental and technical metrics to determine the strength of some 8,000 publicly traded equities. They identify the most tradable issues and sectors with the lowest component of risk. FusionIQ also finds issues with unusual short-term strength or weakness, issuing Buy and Sell signals accordingly. In general, FusionIQ recommends subscribers hold a rolling portfolio of 15 to 20 issues for the intermediate term.
Beyond that, it identifies trading opportunities. FusionIQ models pinpoint highly ranked issues whose prices suddenly gap up 5% or more on high volume (and other conditions). They also issue alerts when analysts with good track records offer earnings forecasts outside peer estimates, and when short squeezes are in the offing — that is, when a highly shorted issue exhibits enough relative strength to force short sellers to cover their positions and boost the price further.
“We don’t care why stocks move,” says Ritholtz, “We just rely on our objective models to alert us to the opportunities.”
Awesome . . .
Calling All Number-Crunchers

MIT’s Andrew Lo: The key concept here, developed by MIT professor and noted hedge-fund theorist Andrew Lo, is “serial correlation.” Simply put, serial correlation is the degree to which each month’s returns in a fund mirror the results of the month before. A fund that returns the exact same amount every month is perfectly serially…Read More
2008 has again been a good year for FusionIQ and its research team. Below are some cherry picked excerpts from Fusion’s various research publications: ● 10/22/07 Bank Index Review (BKX) – “Many of the BKX components: C, CMA, COF, FITB, RF and WM have extremely low technical scores in our FusionIQ quantitative ranking with scores…Read More
One of the strange aspects of running a quant shop is watching some of the fundie guys downgrade previously beloved names long after they have been spanked. Let’s cherry pick a few charts and work our way through them. We’ve noticed this with GM, AIG, and many others recently. Today’s silly downgrade is US Steel….Read More
To most traders and investors, Barry Ritholtz is the voice of The Big Picture, one of the more popular financial blogs on the Internet. Now hosted at ritholtz.com, The Big Picture was one of the more prominent financial must-reads for traders and active investors during the second half of the Bush years. Some of the earliest concerns about the credit crisis and the housing bubble in the financial blogosphere were posted at The Big Picture – a blog that now boasts over a 29 million visitors and 39 million page views.
Barry Ritholtz is the man behind The Big Picture. He is CEO and Director of Equity Research at Fusion-IQ, an online quantitative analysis research firm. He was also recently the Chief Market Strategist for Maxim Group, a New York investment bank, managing more than $5 billion in assets. He is a frequent guest commentator in print, online and broadcast financial media including CNBC, Bloomberg, PBS and Fox Business.
His firm is also responsible for creating an online software tool, at Fusion-IQ, that uses his proprietary metrics to quantitatively rank more than 7,000 stocks and 400 industry groups. The Fusion metrics are backtested and used by both retail and institutional-level investors and traders.
I spoke with Barry Ritholtz by telephone the day after the Presidential election in November. We talked about ETF trading, contrarian trading and creating stories and narratives to help explain the cold, hard probabilities of quantitative analysis. What follows is an edited transcript of lively and insightful conversation with Mr. Big Picture, Barry Ritholtz:
David Penn: First, off I have to ask you about something I saw on The Big Picture this morning about exchange-traded fund (ETF) trading. ETF trading is something we have been very interested in, as well. You had a blog post about exchange-traded funds and leverage exchange-traded funds, particularly the new 3 to 1 ETFs
Barry Ritholtz: We do a ton of ETFs lately.
Penn: Do you? Let me just get your general overview on the rise of leveraged ETFs – including the new 3 to 1 leveraged funds. How effective do you think they are? Why should be traders be interested in them?
Ritholtz: ETFs do some really interesting things. We are bottoms up stock pickers, but in this environment, ETFs make sense. If you want any sort of instant exposure to a sector, a stock, a region, ETFs are just really, really simple, fast and painless. ETFs work well for that. The leveraged funds are really interesting.
Just for a little background: we came into this year (2008) very bearish. We had plenty of longs, but over the summer we were probably more cash than we’ve ever run, 50 to 60 percent cash in our managed accounts. Then as we went through August and into September, well, we have a couple of pretty firm rules about stock losses. We always manage risk by using stop losses. We have some other rules, but it’s long and complicated.
When a stock is working out for us, we try and raise the stop to a breakeven. If you have a big winner, we never want to give back 25 percent of the profits. And there are other mechanical ways of preventing yourself from riding what we like to call the “Cape Matterhorn” stock. Think of Apple in the 1990s; you had a run-up on the iMac introduction. It went from single digits to 100 plus, then back to single digits. This time, with the iPod and the iPhone, it hasn’t quite re-completed the round trip, butits given a ton back. There are plenty of people who ride stocks all the way up, and then don’t know what to do with them and of course, they ride them all the way back down. Ouch.
We hate doing that. So we came into the October lows with just an inordinate amount of cash and a lot of nervous clients. And when we made our bull call on October 10th – which may end up being just a cyclical trading rally, we don’t know and we won’t know for a couple of weeks — there was a real concern of, “I can’t believe you guys are buying here. You’re crazy.” [EDITOR: A similar buy call was made in real time on November 13th, and again, and again, no one complained]
So the approach we took was, let’s buy the two-for-one leverage SSOs (ProShares UltraS&P 500 exchange-traded fund), which are the S&P 500 X 2, and QLDs (ProShares UltraQQQ exchange-traded fund), which are the NASDAQ X 2. And at the same time, we maintained a 50 percent cash position.
Penn: An interesting approach.
Ritholtz: Yes. In a very strange turn of events, we had 100 percent market exposure and 50 percent cash, which if you stop and think about it, is a nice little trick to do.
We could have just gone 100 percent stock, but we never like to pick our points that way. The way that capital deployment worked, it gave us the upside exposure we wanted and yet, at the same time, maintained a modest amount of risk via our cash holdings. Since we don’t care about the actual market movements relative to an individual equity when it comes to stock losses, we had the same stops on the two-for-one leverage stock as if it were GE. It didn’t make any difference. Once it gave up a certain percentage and crossed certain key technical support lines, we were done, we get stopped out — trade over. But that hasn’t happened, so it really gave us this strange and interesting move, relative to what happened.
Penn: What has happened since?
I did a fairly comprehensive interview with the guys over at TradingMarkets.com. We discussed a lot of issues not usually covered in most interviews — quant analysis, probablity theory, uncertainty as the standard condition regarding the future. Some of you might find it kinda interesting: Trading the Big Picture: A Conversation with Barry Ritholtz David…Read More

They’re odd-looking shapes you may never have heard of, but they’re everywhere around you—the jagged repeating forms called fractals. If you know what to look for, you can find them in the clouds, in mountains, even inside the human body.

THE MANDELBROT SET
In 1958, Benoit Mandelbrot begins using computers to explore vexing problems in math. They help him to understand repeating patterns in nature in an entirely new way. He coins the term fractal to describe them and develops the Mandelbrot set in 1980.

ON THE DEFENSE
Though many colleagues initially scorned Mandelbrot’s work, his mesmerizing fractal images launched a popular culture fad. More importantly, his book The Fractal Geometry of Nature explained how his ideas could be applied in the real world. Mandelbrot’s ideas inspire an ever-increasing number of applications, including the fractal antenna.

FRACTALS IN THE BODY
Fractal patterns turn up everywhere in biology, from the irregular rhythm of the heart to basic eye function. The fractal nature of such physiological processes, which obey simple mathematical rules, offers hope of better diagnosis and treatment of problems as well as new insights into how such processes work.

RAY SUAREZ: Finally tonight, we return to a subject on many minds these days: the financial crisis. Our economics correspondent, Paul Solman, checked back in with one particularly prominent voice in the investment world and his colleague, who guided his thinking.
Here is the pair’s sobering conversation on what may lie ahead.
PAUL SOLMAN, NewsHour Economics Correspondent: One of the world’s hottest investment advisers these days, Nassim Nicholas Taleb, author of "The Black Swan," who’s been warning of a crash for years, betting on one, and winning big.
He’s been ubiquitous in the financial media of late, from cable TV’s "Colbert Report" to the BBC’s "Newsnight," where he was infuriated by what he called "bogus accounting."
NASSIM NICHOLAS TALEB, Scholar and Author: The first thing I would get immediately, immediately, I would suspend something called value at risk, quantitative measures of risk used by banks, immediately.
PAUL SOLMAN: We sat down with Taleb and the man he calls his mentor, mathematician Benoit Mandelbrot, pioneer of fractal geometry and chaos theory. And even more than feeling vindicated, they’re both scared.
NASSIM NICHOLAS TALEB: I don’t know if we’re entering the most difficult period since — not since the Great Depression, since the American Revolution.
PAUL SOLMAN: The most serious situation we’ve been in since the American Revolution?
