You Could've Seen David Einhorn's Chipotle Short Coming: Street Whispers

Tickers in this article: GMCR CMG GM AAPL CI

NEW YORK ( TheStreet) -- Chipotle Mexican Grill (CMG) shares shed as much as $1 billion in market cap in Tuesday trading and over 4% after famed short seller David Einhorn of Greenlight Capital unveiled the high-flying restaurant stock as a new short position, citing the company's high price to earnings multiple and a competitive landscape marked by a resurgent Taco Bell, owned by Yum! Brands (YUM) .

At the Value Investing Congress in Midtown Manhattan on Tuesday, Einhorn reiterated the short case for Green Mountain Coffee Roasters (GMCR) and laid out why he is bullish on the earnings prospects of General Motors (GM) and Cigna(CI) , in spite of political and regulatory uncertainty that hangs over both stocks. However, Einhorn's most notable presentation was on Chipotle Mexican Grill -- a battleground stock -- where he's unequivocally now in the bear camp.

Einhorn's short trade took the market by surprise, and has added to a re-pricing of the stock from all-time highs above $440 hit earlier in 2012 -- the stock is down 27% in the past three months since its last earnings report disappointed some investors.

But investors could have seen Einhorn's short coming, even if rumors about Einhorn's stock positions can oftentimes be misleading, as the hedge funder noted in his Tuesday presentation.

In Greenlight Capital's most recent quarterly disclosure of its investments with the Securities and Exchange Commission , the hedge fund's only put position -- an options trade predicting a stock fall -- was in Chipotle. The filing shows that as of the quarter ended on June 30, Einhorn was short Chipotle, even as conversation centered on speculation and rumor.

According to the SEC filing, Greenlight disclosed three separate put positions worth a total face value of nearly $19 million, as of June 30. While it's still unclear how big Einhorn's bearish bet is now that he's publicly made the Denver-based Mexican food chain his next short play, investors could have seen a hint of Tuesday's sell-off coming with the appearance of the Chipotle put.

The only other options position disclosed by Greenlight was a call option position on Microsoft's(MSFT) shares worth a face value of $153 million. According to SEC data compiled by Bloomberg, Apple(AAPL) remains Greenlight's biggest stock position. At the Value Investor Congress, Einhorn said his long-thesis on Apple was "largely unchanged," when asked by an investor in the audience.

For those who are still bullish on Chipotle Mexican Grill in spite of Einhorn's comments, but are concerned by his ability to identify value traps like Green Mountain Coffee Roasters, there's some reason for hope.

Einhorn's condemnation of Chipotle Mexican Grill centers on a thesis that the company's price to earnings multiple appears rich, as players like Yum Brands try to enter the company's territory. That contrasts sharply with Einhorn's short position in Green Mountain Coffee Roasters, which he said was about competition and poor cash flow dynamics, in addition to a highly critical view of the company's accounting and management.
