What does a stock's price depend on?

I would venture to state:

P = f (HS)                                 (1)

Where P is the stock price,
and HS (Happy/Sad) represent the prevailing sentiment towards the stock like the faces on the right.

HS (sentiment) in turn depends on, at least, the following three variables:
  • Market Sentiment - When Mr. Market feels good, everything under the Sun flourishes. However, when he is in a foul mood, it is as if the world is experiencing a nuclear winter when everything perishes. For instance, all Dot Com stocks took off in the 90s and almost all stocks crashed in late 2008! Possible causes for the mood swings:
    • Collective mood swings of the market crowd. There are natural cycles in the collective mood changes of the crowd who can get extremely euphoric and depressive by itself, causing bubbles and crashes.
    • External forces
      • Industry Events: Emergence of new industries: Semiconductors, PCs, Wireless, Internet, Sub-prime lending, Social Media
      • Man-Made events: Authorities' Decisions: Interest rate policy changes, Money Printing/QE, Bailing out or Abandoning certain companies (Bear or Lehman, Greece or no Greece). 
      • Conflicts: Wars, Trade Barriers
      • Natural Disasters: Volcano, Earthquake, Tsunami, Nuclear Accident, Hurricanes, etc.
  • Sector Sentiment - Sentiment changes wildly from sector to sector and from time to time. When the Dot Coms were hot in the late 90s, everything goes up. On the other hand, the traditional industries such as insurance companies hardly took notice.
    • Trends: Emergence of new industries: Semiconductors, PCs, Wireless, Internet, Sub-prime lending, Social Media, Secular demand growth.
    • Sector Challenges: 
      • Hawkish policy: FDA, Regulation of the banks, Nuclear industry
      • Slowing growth: PC, Drug, Brick and Mortar retail industries
  • Company Specific Sentiment - Every company goes thru its love affair with Mr. Market who have many concubines, he does not stay with the same one all the time.
    • Earnings
    • New Products/Inventions
    • Product obsolescence
    • Fraud
    • Competition
    • Interactions with external forces
      • Authorities' handouts or panelties
      • Lawsuits
The next question is how much does P change when sentiment HS changes:

dP = f'(HS) dHS                                                                      (2)

f'(HS) is the first derivative, it is kindly of like beta, which depends on the market cap, industry, stock price, domicile, short interest, etc.

Equation (1) and (2) should not be treated as precise mathematical formulas as in physics, but it is rather an attempt to draw a stock's dependence tree, which hopefully can help to better understand the movements of stocks. In general, dominant variables change over time. Yet too often, market participants are trying to look for one smoking gun (one variable) for explanation. The end result is that it only leads confusion and poor decision making.

    My First Impressions of Apple's Keynote at WWDC

    Apple (AAPL) presented the latest Mac OS (Lion), iOS 5 and iCloud in the World Wide Developer Conference (WWDC). These products are significant and may mark the beginning of another tectonic shift in the tech industry: from PCs to the connected mobile devices and the cloud.

    The most important product is "iCloud". "iCloud stores your content, and wirelessly pushes it to all your devices", and "iCloud is integrated with your apps, so everything happens automatically" said Steve Jobs.  "A competitor that doesn't own apps or does not have great developers to integrate the apps, they can never do this, they can never make 'it just works'." added Steve. Like email, the content (messages) is tightly integrated with the email app, so users don't need to worry about where and how the messages are stored. iCloud is the new digital hub for connected mobile devices. As more sophisticated apps or possibly business apps are developed over time, iCloud will become a more important piece of Apple's ecosystem. iCloud at least doubles the whole Apple's platform's stickiness because developers not only have to deal with the iOS APIs but also the iCloud APIs when they transition their apps to another platform like Android. Not to mention data or content, which are harder to move. Even though Google does not even have anything like the iCloud yet, I do expect Google, a great copycat these days, to follow Apple's footsteps soon, but other competitors like Ressearch In Motion (RIMM), Microsoft (MSFT), Nokia (NOK) and Amazon (AMZN) would have a far harder time to catch up because they are so far behind in the operating system/app/cloud offerings. The new iCloud/iTunes' music match is another well-thought-out, clever and efficient offer, which sharply contrasts with Amazon and Google's comparable "brute force" counter-parts. Some people may be disappointed that iCloud does not stream to the mobile devices. Why should it? Why should Apple worsen users' experience on AT&T? Who said it is a good idea?

    My other important takeaway from the iOS 5 and iCloud is the "demotion" of a PC from a digital hub to just another device. This is done by adding more editing functions to iOS 5 and allowing software updates over-the-air (OTA). iCloud replaces PCs as the new digital hub where iTunes resides along with all the content. The most intelligent part is that everything is done automatically in the background and OTA. The end result is that the whole process is easier for users to create and access content seamlessly from multiple devices. They don't have worry about finding, syncing, saving and backing up the content. "It just works" said Steve Jobs. The demotion of PCs may have a huge impact to the entire PC food chain in the long term. A small decrease in growth rate may not matter much to the high margin players such as Microsoft (MSFT) and Intel (INTC), but it is an issue of life or death for the likes of Advanced Micro Devices (AMD) and Micron (MU), which have razor thin margins.

    One subtle new feature of iOS 5 is the Safari Reader, which allows a user to get rid of distractions or ads when reading an article on the web. It not only improves users' experience, but it also hurts Apple's competitor Google (GOOG), whose "display distractions" may be negatively affected. Obviously, Yahoo (YHOO), who makes a living on display ads and spam, will be much more affected.

    Another new feature of iOS 5 is "iMessages", which allows instant messaging for all iOS devices. This is a very smart move for Apple because it increases the stickiness of iOS devices. Clearly, it is going to take a bite out of the carrier controlled SMS, which has been a cash cow for them.

    There are two other trends about iOS devices worth noting. One is that iPhone 4's cameras may just be good enough to dissuade a typical consumer from buying another alone conventional camera - the losing streak of Japanese consumer electronics makers such as Sony (SNE) continues. Another trend is that Apple's Game Center has more games (over 100,000) and more users (50 million) than the comparable figures for Microsoft's XBox. At some point, I expect Apple to erode the user base of video games. The game developers, console makers and retailers, GameStop (GME) in particular, have good reasons to worry about their growth rate.

    "Lion", the latest Mac OS, contains more iPad-like features such as multi-touch gestures and is only downloadable at Mac App Store. Mac App Store has become the largest software channel for personal software, surpassing Best Buy (BBY) and Walmart (WMT) in just 5 months. If this becomes a major trend for software distribution, it is going to have major consequences to software retail segments for Best Buy, Walmart, GameStop and others. Another trend is that Macs are getting more mobile: the latest laptop sales made up almost three quarters of the total. With the introduction of iPad-like features of App store, multi-touch functionality and long battery life, a Mac laptop is becoming an iPad on steroid.

    In summary, Apple's innovation train shows now no signs of slowing. The people at Apple just "get it"! They just have a fundamentally deeper understanding of the "cloud" than their competitors who are bound by their PC experiences. iCloud and the demotion of PCs will have far greater consequences for years to come. The people, who are disappointed about the lack of a new gadget, are too near-sighted and are missing the forest. Apple's direct and indirect competitors from Microsoft, Google to Sony have good reasons to worry. How can they compete? Apple may not kill your business, but may kill your stock if your growth rate slows as the experience of RIMM and NOK showed.

    Another Chance to Buy Mosaic

    Mosaic (MOS) is the largest integrated phosphate fertilizer producer and third largest potash fertilizer producer in the world. Historically, the stock price closely tracked Potash's (POT) stock until January 18th when Cargill, majority owner of Mosaic, filed to sell 100 mm shares of MOS. Since then, Mosaic underperformed Potash Corp. by roughly 15% mostly due to the anticipated offering of these shares. After the offering finally took place on May 20th at $65/share, the stock quickly rebounded above $70. The recent sell-off brought the stock back down to $66.70 on June 7, giving investors another attractive entry point to own it. I believe the long term prospect of owning fertilizer stocks is very good, given the annual addition of 70 million people to the world population and the continued urbanization or industrialization in the developing countries.

    AMD - A Perpetual Short

    Overview

    The misery for Advanced Micro Devices (AMD) started in 1986 when Intel (INTC) decided to cancel its agreement with AMD as a second source microprocessor producer for personal computers (PCs). Ever since then, AMD has been under Intel's thumb, usually finding itself on the losing side against Intel. The company has been dogged by product delays, short of financial resources and lack of innovative ideas. On one hand, Intel has enough engineering talent and capital to put constant competitive pressure by consistently introducing more and more advanced microprocessors generation after generation. As a result, Intel has been successful in fending off AMD from competing in the high end chips such as the ones being used as the brains of computer servers at data centers.
    That only leaves AMD to compete for the low margin crumbs. As a result, Intel has been a very profitable enterprise with its gross margin being more than 20% ahead of AMD's. Even after Intel outgunned AMD in R&D and capex spending, it still has money left over to return to shareholders through dividend payments and share buybacks. In contrast, AMD has been treating their creditors and shareholders as its ATM whenever the company could not keep up with its bills or needed money to buy innovation.

    As we know, even the worst sports team can win a few games. AMD was no exception as it shined briefly for a few quarters with its successful AM386 microprocessors in the 90s and Athlon chips in the early 2000s when it was able to capitalize on Intel's missteps.

    Financial Drain

    AMD's financial performance mirrored its spotty product history. The company only had three profitable years out of the last 10, during which it lost over $6 billion in total, or $4 billion excluding charges and write-offs, which were once paid in cash or equity. In general, the charge-offs reflect the company's past mistakes that resulted in the destruction of equity value. Struggling companies tend to have more of a history of kitchen sinks than successful ones. Take Eastman Kodak (EK) for instance, extraordinary charges have become a quarterly occurrence ever since the world started to shift from analog cameras to digital ones.

    In a free market, how can a company like AMD be allowed to survive for so long? The problem is that the market is not completely free. There are interested parties who love to see AMD limping along than resting in peace. The first group are the PC makers who want to use AMD as a bargaining "chip" against Intel. The second group are the investment bankers who would do anything for a fee. They are more than happy to keep their fee stream alive by providing equity offerings and subprime loans to AMD.
    These are the same people who facilitated the subprime mortgage bubble, kept the money losing airlines and many poorly run insurance companies alive at the expense of some not-so-smart investors. The past decade was not particularly kind to AMD shareholders who saw their price declining more than 60% from the low $20s to less than $8 at the end of 2010 and their share count being diluted by 127% from 315 million to 717 million.

    Future Prospect

    It is unlikely that the suffering, which AMD endured in the past, will end any time soon. If anything, its future is even more bleak as the PC industry has become more mature and more competitive. In the past, Intel has been using innovation to mitigate the falling prices, but it is getting harder and harder to increase computer power by jamming more transistors into a processor. In other words, Moore's law is getting stretched. This means that innovation will be harder and more costly to achieve. It will have a negative implication for Intel and a grave one for AMD.

    In addition to the slowing growth of the PC industry, the paradigm shift from desktop computing to the cloud is another troubling sign for the PC industry. The main reason that Microsoft (MSFT) and Intel (Wintel) were so dominant in the operating system (Windows) and the microprocessor market was because many critical apps could only be run on their PC platform. When some of the apps started to shift away from desktops to the web or cloud, it gave non-Wintel device makers a more leveled playing field to compete. Therefore, it is not surprising to see Wintel losing market shares to Apple's (AAPL) Macs.

    The increasing popularity of smart phones and tablet computers poses another threat for the PC industry. In general, these mobile devices are more ubiquitous, easier to use and can accomplish a lot of the same tasks that are done on PCs. Microsoft and Intel, which are so dominant in the PC market, could not make a dent in the mobile phone and tablet market even after numerous tries. This was partly because Microsoft and Intel were so fat and happy, and could not focus on the new market with slim profit margins. However, it was a different story for their competitors who had their backs against the wall. Apple Inc., for instance, was almost bankrupt when Steve Jobs returned in 1996. Apple had no choice but to explore a new market. In the beginning, Microsoft treated the new mobile devices as miniature PCs and were not willing to start with a clean slate. As a result, the baggage they carried over from PCs turned out to be too great to overcome. This is because both Windows' operating system and the design of Intel's x86 based microprocessors are a hodge-podge of some old technology and the accumulated fixes over the years. They are not efficient and demand a lot of memory and power to run. This is usually not a big issue for PCs, but a huge one for the new generation of more light weight mobile devices.

    Strategy

    In summary, AMD has a sustainable competitive disadvantage and faces a tough industry headwind. The management has not been kind to shareholders. It is very hard to value the company in terms of earnings, which were mostly negative. Its tangible book value is only about 85 cents per share, which will not provide much support for the stock. In addition, its joint venture with GlobalFoundaries Inc., which makes chips for AMD, could be a financial drain in the future. The company is the exact opposite of a typical Warren Buffett stock.

    Given these factors, AMD makes a great short candidate. The size of the short position should depend on one's portfolio characteristics and risk tolerance. Historically, AMD under-performed the market during the downturns. However, there are some short term risks involved. As a single digit stock in the semiconductor industry, AMD is much more volatile than the general market.

    "Short squeeze" is another risk because the short interest is over 10% of its total float, which is fairly high. There is always a risk that the company will make an innovation that can change its future fortunes. This is a risk for shorting any stock. Given AMD's expertise and its current roster of management, this is highly unlikely.

    Disclosure: I am short AMD, INTC.

    Good AM - a value stock with a shareholder friendly management

    Introduction


    American Greetings Corp. makes traditional greeting cards, gift wraps and party goods. It sells its products mainly through super market stores, Wal-Mart and Target stores. The company derives majority of its revenue and earnings from physical products. However, in recent years, the company developed and acquired many internet properties such as: AmericanGreetings.com, BlueMountain.com, Egreetings.com, Kiwee.com, PhotoWorks.com and WebShots.com to offer their eproducts. 

    Because of its heavy reliance on the traditional products and distribution channels, the company is products are perceived to be obsolete over time. As a result, the stock attracted a lot of short sellers: 22.6% of the total float!

    Is the company fading away any time soon? 

    Given the rage of the internet, one would expect their business be fading fast. In reality, it was not so clear! In fact, their total greeting card business grew by 7.5% (7% due to volume and 0.4% due to price) during their fiscal 2010 year ending February of 2010. Their latest quarter ending November 26, 2010 showed a flat year over year growth, excluding diversified party goods business. In the past 5 years, their total revenue only declined about 3.3% a year. It is safe to say that their business is not going to fade away any time soon. Their business is not exciting, but it certainly beats PCs where price erosion is much greater.

    Valuation


    The company is expected to earn about $2.44 a share for their current fiscal year ending February of 2011. As of the end of November, 2010, it has a tangible book value of $673 million, which increased by $104 million from 2009. At $22.3 a share, it trading at a multiple of 9.1 and a price to tangible book ratio of 1.32. It also increased its quarterly dividend from 12c to 14c to an annual yield of 2.5%. Assuming the company's business is stable, an investor is getting paid to wait. I believe the downside is limited, and upside is substantial as well. 


    Shareholder Friendly Management


    American Greetings has been a family owned and operated business for over 100 years. The current Weiss family owned about 3% of the shares. There is no doubt their interest is aligned with share holders, a rarity these days. They retired over 26 million shares, or 40% of total shares, in the past 5 years. They smartly bought back over 7.9 million shares in 2009 under $10 a share, what a valuation creation for shareholders! They also patiently waited to acquire BlueMountain.com from At Home, a hot internet company, at a fraction of the price that At Home paid 2 years before! I don't know if the purchase is paying off or not, but it does show the discipline the management exhibited in making the acquisition because it was common for traditional companies to pay billions of dollars to buy a dot com start-up.

    Key Challenges and Risks
    • Accelerated deterioration in their businesses: There is always a chance that their traditional greeting card business experience a sharper (than historic) decline due to new technologies. However, I don't think this is likely. This is because their typical customer is a 47 year old female who has been their customer for years. In general, it takes time for people to change their habit. This is exactly the long term challenge the company is going to face: how can they target their business to a younger generation? I believe the more realistic threat is from the popularity of dollar stores where the cards are a lot cheaper.
    • Concentrated Distribution: Wal-Mart and Target represent 14% and 13% of their fiscal 2010 sales. If any one of them decides to jump ship, it would have a sizable impact on the company.
    • Bad Acquisitions: It is very common for companies to make bad acquisitions (just to buy revenue) in a mature or struggling industry because very few companies want to be liquidated even though it is very often the best option for shareholders. The company acquired quite a few web properties. It is not at all clear all the "new new" web properties will be good investments as a whole. This is one area investors should watch very carefully. A bad sizable acquisition would just defeat all the value arguments stated so far.

    Mark Andreessen's Investment Criteria for his venture fund

    1. Size of the market - Big market
    2. 10X change - The new products have to be 10 times better than the existing ones.
    3. Management Team

    Li Lu's Investment Criteria

    1. A stock is not a piece of paper, it is a piece of ownership in a company.

    2. You need a margin of safety so if you are wrong you don't lose much.

    3. In the market, most people are in it for the short term. It allows you a frame work for dealing with day to day volatility.
