Sunday Musings: Fooled By Randomness

Ulli Uncategorized Contact

My preference is to read business books that offer a fresh perspective or a different view of looking at things. The same applies to books that deal with investments. Most aren’t worth the paper they are printed on because they rehash MPT, Modern Portfolio Theory (which by now is some 60 years old and in dire need of revamping), or focus on why ETFs are better than mutual funds along with the same old Buy & Hold scenario.

All of these are approaches that are based on a bullish environment and, when the bear suddenly appears, those portfolios get slaughtered big time. Of course, heavy bear market losses get swept under the rug in a hurry by the media and by many of the most well-known B & H proponents.

Bear markets can be considered Black Swans, or rare events, as I wrote about last year. In my advisor practice, I like to be prepared as best as I can to deal with those events by being disciplined and always have an exit strategy to fall back on. To me, if a bear market has the power to slice portfolios in half over a fairly short period of time, then one should pay attention and be prepared at all times.

I was reminded of that again when I read Nassim Taleb’s book “Fooled by Randomness,” which further elaborates on the Black Swan concept. Nassim explores how randomness not only affects the markets but also makes inroads into your daily life. It’s a fascinating read and gives some insight in how the author himself, a mathematical trader, is trying to resist being fooled by randomness and how he tricks his emotions in regards to probabilistic outcomes.

He cites examples of high profile traders making hundreds of millions of dollars for their employers only to lose more than that in just one week, because they did not consider the possibility of career ending rare events. I was shocked to learn that only very few of the top traders working for investment banks base their decisions on certain observations (that includes past history) and then make sure that the costs of being wrong are limited. Here’s what Nassim said (page 131):

They know (the traders) before getting involved in the trading strategy which event would prove their conjecture wrong and allow for it. They would then terminate their trade. This is called a stop loss, a predetermined exit point, a protection from the black swan. I find it rarely practiced.

Read that last sentence again! This is only way I know of to protect your portfolio from receiving a serious haircut, yet most investment approaches, especially those based on Buy and Hold, do not allow for it. Whether you call it randomness, a rare event, a black swan or any other name, the outcome will be the same.

I believe that especially in a bubble bursting economic environment with worldwide effects, such as we have been experiencing, not paying attention or simply ignoring the possibility of a bear market, will have dire consequences for those in denial.

If with all my blog posts, I can get only one idea across to you, which is to never ever work without a sell stop, then my efforts will have been successful.

Somebody Else’s Words Of Wisdom

You constantly hear me harping on the essentials of trend tracking, such as keeping your losses small by using a clearly defined exit strategy, accepting whip-saws as a necessary part of investing, letting your profits run and many others.

It appears that I am not the only one using these ideas. The WSJ posted a story titled “If It Feels Bad, It’s Probably A Good Trade,” which features hedge fund manager Lorenzo Di Mattia, and how he handles the emotional ups and downs and the frustrations of the market place.

Here are some snippets:

Emotions are contrarian indicators, says Lorenzo Di Mattia, manager of hedge fund Sibilla Global Fund.

Actions that make us feel good are usually a lot less profitable than the ones that make us feel bad or stupid,” says Mr. Di Mattia, who manages about $400 million and trades stock index futures, currencies, Treasurys and commodities in addition to going long and short stocks. “The best trades are usually painful.”

Mr. Di Mattia prefers to concentrate his capital, doing a series of big short-term trades, and building up positions to as much as $300 million in each one. With positions that big, the needle moves fast. He’s only willing to lose the equivalent of 1% of assets under management on a single trade before he exits.

After doing his homework on currency and economic trends, Mr. Di Mattia shorted the New Zealand dollar against the yen and the greenback early last week. The fund manager had a twofold investment in the idea that the NZ dollar would drop in value: financial and emotional. So it stung on Thursday when the New Zealand government delivered unexpectedly generous income-tax cuts, and the local currency rallied. Yet the most painful part was closing the position, he says.

Taking losses before they get too big and out of control implies the admission of a mistake, and hurts twice (the loss, and the fact we feel stupid) … You have to admit that, at best your timing was wrong, or maybe your whole idea was wrong,” Mr. Di Mattia said.

The feelgood option is to ignore the market in the belief that the idea will eventually come good. Kind of like not going to the doctor because those burns will probably heal on their own.

Taking small losses is the only way to avoid big losses,” Mr. Di Mattia says.

Another painful strategy that he’s found profitable: going right back into the same trade with the burns still fresh on the fingers. As Anthony Burgess’s novel, A Clockwork Orange, memorably demonstrated, learned aversion is a tough instinct to overcome.

“Just because the trade was wrong at that time doesn’t mean you drop it altogether,” says Mr. Di Mattia. “Sometimes you even have to do it at a higher price, and that really hurts. When the trade works, you have to do it.”

Mr. Di Mattia dived back into the short New Zealand dollar trade late last week.

Even if the trade goes his way this time, the decisions may be painful. One of the toughest feelings to fight is the urge to take a profit, he says. The further into the green the trade goes, the stronger the inclination to close it. In today’s momentum markets, that can mean leaving the party before it even gets started. For a hedge-fund manager, that’s a real pain.

Even though a hedge fund may have different objectives (more aggressive) and a shorter time frame for its trades as opposed to a long-term investor, the principles mentioned remain the same.

No Load Fund/ETF Tracker updated through 5/29/2008

My latest No Load Fund/ETF Tracker has been posted at:

http://www.successful-investment.com/newsletter-archive.php

Decent economic news and lower oil prices helped the markets stage a nice rebound.

Our Trend Tracking Index (TTI) for domestic funds/ETFs has now moved to +1.42% above its long-term trend line (red).



The international index improved as well and now remains -2.06% below its own trend line, keeping us on the sidelines.

Zigzagging Higher

Wednesday’s good news in form of a better than expected durable goods report was overshadowed by a rebound in oil prices causing continued worries about the impact on consumers.

Nevertheless, the major indexes managed a decent afternoon rebound, despite the financials being a big drag. This was caused by an analyst’s opinion that AIG’s recent $20 billion raise in capital may not be sufficient and that the insurer’s financial position could worsen.

That’s not surprising to me, since I believe that the fallout from the real estate/credit bubble, and the fact that many investment banks are still stuck with worthless, leveraged holdings, has not fully played out yet.

Be that as it may, yesterday’s activity affected our Trend Tracking Indexes (TTIs) positively, and they improved slightly:

Domestic TTI: +1.20%
International TTI: -3.01%

A fact is that prices tend to decline faster than they rise. If the markets decide to resume the previous upward trend, chances are that it will take a lot longer than the 5-day drubbing the major indexes took last week.

However, since we don’t control those factors, we will focus only on what we can control, which are our sell stop points. Yesterday’s activity had no effect, and we will hold all positions.

Uncertainty Reigns

Uncertainty was the word of the day on Tuesday as the markets see-sawed (see chart from Marketwatch.com). However, after the drubbing of last week, momentum picked up late in the session supported by a drop in oil prices and an unexpected gain in new home sales.

On the other hand, continued lower consumer confidence figures kept a lid on advances. I suspect that some further sideways action will dictate trading in the near future until some catalyst can propel the major indexes higher again. In the absence of such a catalyst, we may be treading water for a while longer. Here’s how our Trend Tracking Indexes (TTIs) fared yesterday:

Domestic TTI: +1.09%
International TTI: -3.20%

Domestically, we’ve slipped back into the neutral zone and will hold our positions subject to our trailing sell stop points.

With energy prices being on the front burner, despite today’s pullback, I have added a position in that area last week, along with gold, which broke out to the upside but retreated today.

Money Making Schemes

Ulli Uncategorized Contact

Recently, I had a discussion with a client who marveled at the ability of Wall Street firms to make money. He assumed, like many other investors do, that many high powered firms have superior stock picking abilities or staff with the foresight to properly assess the next hot investment trend so that the firm can get in on the bottom.

Generally speaking, that’s not how the money is being made. Sure, being in on worthwhile IPOs will always generate large sums of money, but even more is being made (and lost) in the derivatives business.

While I will elaborate on that further with a special post within the next couple of weeks, I was reminded of it when I read the latest fraud investigation on Mish’s Global Economic blog titled “Fraud, Antitrust Investigation Involving JPMorgan, Jefferson County.”

It’s a stark reminder that all is well and good on Wall Street, and the events of the Orange County bankruptcy in the 90s (due to derivative investments) have been long forgotten.

Here’s an excerpt of the latest derivatives debacle:

The Largest U.S. Municipal Bankruptcy Looms in Alabama. What caused this mess is an interest rate swap Jefferson County officials entered into when they financed a $3.2 billion sewer cleanup. The strategy backfired, demonstrating the speculative, risky nature of swaps.

Like homeowners who took out mortgages they couldn’t afford and didn’t understand, Jefferson County officials rejected fixed- rate debt and borrowed instead at rates that varied with the market.

The county paid banks $120 million in fees — six times the prevailing rate — for $5.8 billion in interest-rate swaps. That was supposed to protect the county from rising rates for their bonds. Lending rates went the wrong way, putting the county $277 million deeper into debt.

That means local officials now have to pay to banks money that otherwise might have been used to build schools, hospitals or public housing.

Meanwhile, the U.S. Securities and Exchange Commission and the Justice Department are now investigating bankers and officials involved in Jefferson County’s swap agreements.

[emphasis added]

It pays for you to read the entire story, but suffice it to say, that’s the way big money is being made—not by trying to pick the next hot stock. The eventual outcome of this debacle will be the same as always: A few heads will roll, some fines will be paid but, afterwards, it’s business as usual.

As for the rest of us, we have to take the hard road by investing responsibly and conservatively especially when other people’s money is involved. The markets don’t make this always easy, especially when we’re trending sideways; we have to tough it out and stick to our plan in order to succeed long-term.

While this route may not make my clients hundreds of millions of dollars, it let’s me sleep at night knowing that we work with integrity by never having to worry that we were part of a scheme that brought down an entire county.
