He reports that LTCM established an arbitrage position in the dual-listed company (or “DLC”) Royal Dutch Shell in the summer of 1997, when Royal Dutch traded at an 8%–10% premium relative to Shell.

The essential thing is to manage your risk in a consistent fashion and allow for large deviations from observed conditions. Both LTCM and RenTech used a tremendous amount of leverage, and developed sophisticated risk-managing models. But you don’t have to get terribly sophisticated to understand that frequent small, uncorrelated bets with quick profit-taking is far less risky than enormous, correlated bets that may take many months to be realized. How do we invest in unprecedented times and conditions like these? LTCM made the mistake of thinking that the unprecedented conditions they faced were temporary, that things were bound to go back to the way they were, and that this would happen quickly enough to save their hides.

I display hubris from time to time, but try to keep it in check. I trade relatively illiquid stocks, but manage my trades and my portfolio carefully. I’ve done extremely well by taking unusual positions, doing a lot of research, and thinking mathematically. I’m an ignorant amateur compared to the folks in these books. I want to continue When Genius Failed winning, and thinking myself a genius won’t help me with that. After all, I’ve made plenty of mistakes, and I’m certain I’ll continue to make plenty of mistakes. And the missteps that the partners in Long-Term Capital Management made were made not because the formula that they used was wrong, but because they stopped using the formula.

The partners were arbitrageurs who used enormous leverage, and when their positions became too big to efficiently arbitrage, they started to place one-sided bets, or failed to sufficiently hedge, or took liquidity for granted. Managing a small risk is very different from managing a large one, and much easier too. Did genius actually fail, or did the partners stop acting like geniuses?

VaR also couldn’t interpret extreme event such as financial crisis in terms of timing. The model failed to recognize that a financial crisis was a rare event and thus produced biased calculation results. Economist Eugene Fama found in his research that stocks were bound to have extreme outliers. Furthermore, he believed that, because they are subject to discontinuous price changes, real-life markets are inherently more risky than models.

He became even more concerned when LTCM began adding stocks to their bond portfolio. Opaqueness may have made even more of a difference and investors may have had even a harder time judging the risk involved when LTCM moved from bond arbitrage into arbitrage involving common stocks and corporate mergers. LTCM was open about its overall strategy, but very secretive about its specific operations, including scattering trades among banks.

But he knew how much antipathy there was in the room toward Long-Term. He thought the odds of getting the bankers to agree were a long shot at best.

There may not be any parallel in this technique to what either LTCM or RenTech did, since they weren’t stock-picking at all. But successful stock-picking isn’t just finding stinky stocks that nobody else likes, or brilliant gems that are temporarily undervalued. You can do that all you want, but if you’re not a successful When Genius Failed portfolio manager, you’ll find yourself overstretched and on thin ice. Model your portfolio strategy, backtest it, figure out how you can maximize your long-term returns safely, subject your models to the most extreme stress tests you can think of. The way to make money in stocks is to avoid risk, not to court it.

No public money was injected or directly at risk, and the companies involved in providing support to LTCM were also those that stood to lose from its failure. The creditors themselves did not lose money from being involved in the transaction. Historian Niall Ferguson proposed that LTCM’s collapse stemmed in part from their use of only five years of financial data to prepare their mathematical models, thus drastically under-estimating the risks of a profound economic crisis.

This recession is already unlike any other; so were the last two, and the next one surely will be too.
