A Look At Trend Following Hedge Funds And the Algos That Love Them

Wait, algorithms can't love, not unless they're sentient, right? and they're not, Right?
From the Financial Times:

Hedge fund nightmare turns into a dream
Do computers that trade financial markets ever have nightmares about losing money? It is a question investors have asked in recent years of the hedge funds that use automated algorithms and models to buy and sell billions of dollars of assets.
Having almost consistently made money in the decade leading up to the financial crisis, these so-called trend following hedge funds appeared to have been scrambled by the high correlation across markets caused by ultra-low interest rates and central bank intervention.

While the money being lost was just another data entry for the computers buying and selling assets ranging from pork belly futures to Japanese government bonds, their creators faced the very human stress of investors losing faith in their investment strategy.

As the funds came under huge pressure to remodel their apparently malfunctioning computer programs, some investors even began to argue that trend following systems were permanently broken – that the mathematicians and scientists should close down their spread sheets for good.

“No matter how much we have a statistical, disciplined and scientific approach to investing, that doesn’t mean that as a human you don’t watch your returns going down in periods of poorer performance and experience all the negative emotions that losses entail,” says Ewan Kirk, chief investment officer of UK-based hedge fund manager Cantab.

But the managers, who go as far as sending researchers to the British National Archives to extract grain prices from the Domesday Book to construct trend following models, remained convinced the strategy would recover.

“When people doubted trend following, it reminded me of people giving up on value investing before the technology bubble burst, at exactly the wrong time,” says Sandy Rattray, chief executive of Man Group’s AHL, one of the largest and oldest of this type of hedge fund. “Studies have shown that momentum has worked well over long periods. It was a brave person who said that momentum was permanently broken, but many did at the beginning of 2014.”

Having begun the year as the most hated hedge fund strategy, many of these trend following funds have emerged as the best performing funds of 2014, outpacing their stock picking rivals who rely on mere human intuition to make money.

Helped by large moves in commodities, energy prices and interest rates, as well as the ongoing devaluation of the Japanese yen, funds like AHL, as well as rivals such as Cantab, and Isam, have all reported double digit returns for their investors this year. In contrast, many well known funds following other strategies, most notably global macro traders, have lost money this year....MUCH MORE

So why do commodity funds use trend-following?
Because trying to catch the turns is so dangerous to bonuses that the practice is best left to bloggers and other lunatics.
(sorry, still gloating over trading the recent S&P V-bottom almost perfectly out in public, on the blog, in real time, backwards, in heels: from warning in advance to calling the day of the bottom to cheerleading the upmove to new highs-waddya mean "Memento Mori", where's my laurel wreath, I'm going on parade)
