Lehman is uncertain. Merrill is uncertain. Morgan is uncertain. Goldman is uncertain. And of course how could I miss out Bear Stearns!
Where is Wall St. headed?
The financial markets, they say, move in circles. The rally and frenzied selling are intrinsic parts of it. Have we seen this type of a movement in the market?
The answer is – Yes, at least 2 of them.
The most recent one being in 1997 when LTCM lost their foothold even with the behemoths of Quantitative finance backing the structural construct of complex fixed-income arbitrage trades. Convergence trades as they are known were the most common.
Let’s start with the basic concept of Convergence. The word by itself means – The act, condition, quality, or fact of converging. In Mathematics it means – The property or manner of approaching a limit, such as a point, line, function, or value.
A convergence trade with respect to the fixed-income market was based on the idea that long-term bonds issued around the same time would eventually ‘converge’ to the same price/value. The rate at which they converged would be different depending on their liquidity. An on-the-run bond is always more liquid than a off-the-run bond. The convergence would take place as new bonds would come on the run. (That’s funny ‘come on the run’ – but let’s not digress).
Thats a unique bond-arbitrage position. Buy off-the-run bonds at a cheaper price and short-sell on-the-run bonds. So where is the catch? The trick (or should we call it the downfall of LTCM) was highly leveraged positions. Since the differences in the values of these bonds were really small, the positions had to be highly leveraged in order to make a decent buck.
Did the leveraged positions define the downturn? -no, but they were a major factor in defining the effect it had on LTCM. Causality is but a post-action study. What did define the downturn was the loss of liquidity and a spike in the volatility in the market. After the Asian Market crisis (1997)and the Russian financial crisis (1998) the Global markets lost a ton of liquidity, prompting the investors and banks alike to run for cover under the umbrella of US Treasuries. The so called zero-default-risk bonds. As the demand went up so did the prices and instead of converging they ‘diverged’. To unwind these positions meant huge losses for LTCM and eventually their assets were wiped out.
LTCM’s impact was felt all across the US as almost all of the big banks and investment firms pooled in to contribute money to LTCM to cover their asses!(sic) Without significant contributions, LTCM would have had to liquidate a lot of it’s securities to cover it’s debt which would lower prices and in turn other companies would offload their debt creating a complete downward slide in the debt/credit market. That of course did not happen since LTCM was bailed out.
So how is this related to the markets now and where is Wall St. headed?
We see the same trend – Low liquidity – High volatility and more risk-averse investors. Let’s talk about that in the next post. I also want to talk about:
1. Black-Scholes (since Martin Scholes was part and parcel of the quantitative trading strategy development team at LTCM)
2. Martingale (probability and betting theory)
3. Game theory.
The last one being my favorite (cos it teaches you how to get to the blonde without being rejected!)
LTCM stands for Long Term Capital Management.
