Are Interest Rates Being Driven Into Negative Territory By Computer Programs Gone Mad?
Here is a very interesting report by Laurence Fletcher at the Financial Times:
The growing pool of negative-yielding debt makes this a hostile environment for most bond investors. Yet some hedge funds have still managed to find ways to turn a profit from the advent of sub-zero rates.
Concerns over weak global growth and drooping inflation have pushed around $15tn of bonds to trade with negative yields — meaning a buyer is sure to lose money if they hold the bonds to maturity.
Some money managers trading these bonds have nevertheless chalked up big gains for the year. One of the most obvious strategies has involved simply riding the big rally. Yields fall as prices rise; managers who clung on to their holdings as yields tumbled below zero have reaped juicy profits.
Among the biggest winners are computer-driven hedge funds that try to latch on to market trends. While many human traders may question the wisdom of buying or keeping a bond that apparently offers a guaranteed loss, robot traders that monitor price moves have no such qualms.
GAM Systematic’s Cantab Quantitative fund has gained 36.1 per cent, according to numbers sent to investors, with the biggest gains coming from bets on falling bond yields.
Stockholm-based Lynx Asset Management’s main fund is up 20.7 per cent while a smaller, more leveraged fund it manages has gained 30.6 per cent, according to numbers sent to investors. Lynx has been running close to the maximum bet it is permitted on falling bond yields, said a person familiar with its positioning.
To the degree it is such program-driven trading, it implies heavy trend following that once the trend reverses (and it eventually will), the reversal could happen very rapidly and the losses will be severe.
