In light of the market’s move yesterday we thought we would publish a sample of some of our favorite writers from the blogosphere. Any single day drop cannot usually be attributed to any individual factor. When the market moves it is usually the result of a combination of factors. Trying to weave a coherent narrative is a fool’s errand.

Barry Ritholtz at the Big Picture takes a closer look at how the day in the markets played out.

FT Alphaville on the cacophony of pundits trying to explain the market’s move.

Felix Salmon on why honest journalist should just say, “the market down and we don’t know why.”

Brett Steenbarger at TraderFeed on what usually happens after a large one-day price decline.

Highly skewed volume days led to widely divergent performances according to Jason Goepfert. (quoted at MarketBeat)

Eddy Elfenbein at Crossing Wall Street with a little perspective on the “broad based sell-off.”

Eric Savitz at notes that yesterday was “nothing” in comparison to historical drops.

David Leonhardt in the New York Times on the stealth recession in manufacturing.

macroblog and Econbrowser sum up the state of the economy as we know it.

Greg Newton and FT Alphaville on a short-selling hedge fund closing down for lack of attractive opportunities.

Mebane Faber at World Beta on how some hybrid fund managers did on a big down day.

Adam Warner at the Daily Options Report has a plan on how to proceed in a time of “disequilibrium.”

Jeff Miller at A Dash of Insight has some perspective on the drop and is finding attractive opportunities.

Howard Lindzon on the importance of discipline and money management.

Jeffrey Ptak at is finding some large cap buying opportunities “aplenty.”

Going Private on what the market drop means for one big Wall Street firm.

James Picerno at the Capital Spectator and Random Roger on the value of diversification.

As usual, no forecasts here. However big down days highlight the need for every investor to have a well-defined (and reasoned) plan in place BEFORE things like yesterday happen. That, and having a well-diversified portfolio to begin with. Good luck out there. We will check in later in the day with another linkfest.
