FORTUNE -- Want to know what the big hedge funds are up to with Apple (AAPL)?
The only public disclosure they are required to file are the SEC Forms 13F due at the end of each quarter.
The 13Fs for the Q4 2013 came in Friday, and according to Whale Wisdom's Daniel Collins, Apple topped the list once again -- both in terms of the number of firms holding the stock and in the value of their holdings.
Apple closed Dec. 31 at 557.68, up 18% for quarter, but the aggregate number of shares held by firms with over $100,000 in management actually fell 1.68% -- perhaps because Apple was in the market buying up its own stock.
Overall, according to Collins' summary:
238 funds created new AAPL positions
772 funds added to an existing AAPL position
72 funds closed their AAPL position
775 funds reduced their AAPL position
The devil, however, is in the details.
Morgan Stanley, for example, bought 1.36 million shares of Apple last quarter -- more than any other fund -- which makes sense given Katy Huberty's "overweight" recommendation and $630 price target.
But J.P. Morgan's Mark Moskowitz also rates Apple "overweight," yet his bank sold nearly 1.7 million shares last quarter.
The picture gets murkier when you throw in options -- the right to buy 100 shares (a "call") or sell 100 shares (a "put").
Citadel Advisors, for example, might pass for an Apple bull based on the 1.05 million shares of the stock it bought last quarter. But in the same quarter Citadel sold 2.1 million calls and bought 83,500 Apple puts -- one a bet that the stock isn't going up anytime soon, the other a bet that it's headed south.
Note also how much of the heavy bearish options trading in Apple last quarter was conducted by firms that seem to have come out of nowhere: Integral Derivatives, Spot Trading, Oz Management, Pine River Capital Management, KCG Holdings, DRW Securities, QCM Cayman, Peak6 Investments, Virtu Financial, Jane Street Holding.
It's a brave new world out there, and largely unregulated.
UPDATE: Below the option spreadsheets I've added, per reader request, the holdings and their value of the four funds with the largest stake in Apple: Vanguard, State Street Bank, Fidelity and Blackrock, in that order.
Until recently, takeover bids were rare in Japan, where private equity and hedge funds have been traditionally viewed as vultures.

FORTUNE -- Sony's best selling TV, the Bravia, translates as "ferocious, savage, wild, untamed" -- the very adjectives that are probably on the minds of Sony executives as they consider the latest bid from gaijin, or outsiders, to upset the highly ordered decorum of doing business in Japan.

What they care most about, a survey of 365 sell-side analysts found, are hedge funds.
FORTUNE -- As someone who has been tracking the forecasts of Apple (AAPL) analysts for nearly five years, I was not entirely surprised to learn that when 365 sell-side analysts (not just covering Apple) were asked what factors affected their compensation, the accuracy and timeliness of their earnings forecasts came in dead last.
This revelation comes from a survey MOREPhilip Elmer-DeWitt - Apr 30, 2013 12:46 PM ET
Funds that were buying one and shorting the other are reportedly unwinding their trades
FORTUNE -- This was news to me.
Starting in February, according to Thomas Kee, who runs an outfit called Stock Traders Daily and writes a column for MarketWatch, hedge fund traders were buying Google (GOOG) and shorting Apple (AAPL).
"The trade worked quite well until about one week ago," Kee writes in Thursday's column, which is when the media MOREPhilip Elmer-DeWitt - Mar 14, 2013 12:38 PM ET
Because 13 of the 50 largest U.S. hedge funds were dumping their Apple holdings
FORTUNE -- Citigroup's Tobias Levkovich buried the lead when he reported Wednesday that Google (GOOG) had replaced Apple (AAPL) as the hedge funds' favorite stock in Q4 2012.
If you zoom in on his spreadsheet above (apologies for the bad reproduction) you'll see that Google made it on to one more top 10 list of the 50 largest U.S. hedge funds MOREPhilip Elmer-DeWitt - Mar 10, 2013 8:45 AM ET
How an Internet-trained Apple analyst lost tens of millions of other peoples' money
FORTUNE -- In the late 1990s, an ad agency creative director I'll call Joe Smith bought several hundred shares of Apple (AAPL) at $60 apiece. Last fall, at age 42, he found himself out of work and increasingly dependent on the value of those shares to make ends meet.
Following the lead of a 33-year-old investment advisor named Andy MOREPhilip Elmer-DeWitt - Mar 4, 2013 1:07 PM ET
SEC filings show banks and hedge funds selling Apple shares by the millions
FORTUNE -- There was a lot of selling pressure on Apple (AAPL) last quarter, to put it mildly. The stock ended the year down 25% from its September high of $705.07 and has fallen another 12% since then.
Want know where that pressure came from?
The big financial institutions -- banks, insurance companies, hedge funds, pension funds etc. -- that MOREPhilip Elmer-DeWitt - Feb 15, 2013 7:33 AM ET
A gathering of hedge fund managers in Manhattan sends the share price on a wild ride.
FORTUNE -- See on the chart at right where Apple's (AAPL) share price dropped to just over $540 shortly after 3 p.m. Wednesday?
That corresponds roughly to when the fund manager pictured above left, DoubleLine Capital's Jeffrey Gundlach, told a room packed with investment managers that he was shorting Apple. "I just wonder how many people will MOREPhilip Elmer-DeWitt - May 17, 2012 8:03 AM ET
The insider trader who pled guilty Tuesday leaked details about the iPhone 4 and the iPad
The wiretap caught it all.
Walter Shimoon, then a director at Flextronics (FLEX), a Singapore-based company that supplies Apple (AAPL) with camera and battery components, was being paid up to $200 per hour to leak insider information to a shadowy group of hedge funds and so-called expert networks.
In an Oct. 1, 2009 phone call secretly taped MOREPhilip Elmer-DeWitt - Jul 6, 2011 5:57 AM ET
When the stock sets new record highs, the naysayers come out of the woodwork
As a rule of thumb, never take investment advice from a hedge fund manager who posts his predictions on Twitter.
On Thursday morning, BAM Investor's J.G. Savoldi used the microblogging service (and a follow-up press release) to warn investors that Apple (AAPL) was about to crash and could hit $45 a share -- perhaps as early as this MOREPhilip Elmer-DeWitt - Jun 19, 2010 6:52 AM ET
