Factors behind the market's undoing were clear to many, says analyst

NEW YORK (MarketWatch) -- The stock market's recent collapse calls into question the soundness of one cornerstone of modern financial theory -- the idea of "efficient markets" -- since all the components that conspired to produce the mess were in plain sight, contends one analyst.
"Anything that purports to describe the last 18 months as 'efficient' seems like a cruel joke," said Nicolas Colas, chief market strategist at BNY ConvergEx Group.
The premise behind the term holds that available information about a given security is quickly baked into its price, yet Colas says in the latest market decline, stock prices ignored the news until the situation threatened the likes of a Lehman Brothers.
"All the factors that created the market's collapse were hiding in plain sight in brokerage firm 10-K filings and news reports about the housing and mortgage markets. Hundreds, if not thousands, of individuals knew the risks in the collateralized debt obligations and credit default swaps marketplaces. Many of them even work in one place -- New York City," said Colas.

"We suspect the academic community will have a hard time explaining away the destruction of half of the value of the U.S. stock market in a little over a year after it took 70 years to create much of that same wealth," the analyst said.
The recent market collapse also discredits the common wisdom of near-certain returns if one holds stocks for five to 10 years.
"That's another one we can throw out the window, but you can flip the coin, if you've made your 10% for 10 years, then get out," said Colas.
Colas also rejects the notion of using math as an investment edge, saying those who believe they can call on market bottom based on S&P 500 earnings estimates and "some notion of a 'normal' P/E" should reconsider. "The reason the market bottomed is not because we hit some magical P/E ratio," the analyst said.
Instead, Colas advises trying to devise a more complete picture of where corporate valuations may end their fall, looking at current economic and business fundaments to help determine what fundamental scenario might develop as the recession wanes.
"What I've tried to say is don't baseline your expectations on the notion that markets are as efficient as the academic world wants to believe, think for yourself," said Colas.
On Wednesday, stock restarted the prior session's rally after the Federal Reserve surprised the market by saying it would buy $300 billion in longer-term Treasurys to help the ailing economy. Read The Fed.
