  • Tesla - Driven By Noise, But High-Quality Noise [View article]
    "I had to go back through your article and see if you outlined the idea of noise and that I had missed it. But I didn't see it. "

    It was in the first article:

    "If you expand this concept into a seminar, I hope you are, please message me and tell me where I can get that seminar."

    Don't know where you live, but it will be part of a presentation I'll be giving to the AAII Chapter in Cleveland on May 14

    "how do you determine noise?"

    See my prior article, which addressed that in considerable detail:

    Buyandhold 2012,

    I'm quite familiar with Warren Buffett given that back in the late '90s, I was the first analyst anywhere to bring BRK under regular coverage. He's definitely a bright guy and a living legend. But he is not the only bright guy around. As noted in my prior article and in response to some other comments above, this framework originated with Robert Shiller, who is also pretty powerful in the IQ department and as aware as anybody of the dangers of irrational asset pricing.

    And FWIW, the blase statement that TSLA should trade for 20 times 2014 earnings is not even a competent apprach to valuation, whether for TSLA or anything. PEs are not drawn from thin air.

    "This is a perfect example of irrational exuberance."

    Interesting reaction. The whole approach comes from a paper by Robert Shiller (, the same Robert Shiller that published the book entitled "Irrational Exuberance."

    "It is pretty subjective thing and will definitely involves human factors. "

    That's a fair statement. The Robert Shiller paper on which this is based was titled "Stock Prices and Social Dynamics."

  • Staples: Why Lousy Companies With Great Managements Are Still Lousy [View article]
    "In my view, this is because customers are realizing that Staples retail stores offer very little advantage over Wal-Mart (WMT) and other big-box stores. Virtually everything that can be bought at Staples can be bought at a similar price somewhere else."

    I have problems with SPLS stock but this is not one of them. I and many other would rather have a root canal without anesthesia than walk into a Wal Mart store, but even for those who can stomach that horror, let's not underestimate in-stock availability. SPLS has stuff and price competition aside, when you need stuff, the store that has it on the shelves is preferable to the one that doesn't.

    Obviously, though, they are going to have to adjust to the modern office environment and that will probably mean a smaller company than suggested by the current market cap. But while they wrestle with that, let's not over-rate management which, may, actually, be their weakest link. When I went to a store to buy a graphic calculator for my kid, they were so desperate to get me to buy a useless and overpriced $7 warranty they actually took $10 off the price of the calculator if I'd do it (which I, of course, did). I asked them why they'd do such a crazy thing and they said it was because the "higher ups" wanted to show a lot of warranty sales. So market conditions aside, anybody who invests their money in a company managed by people like that deserves what they are likely to get.

  • Amazon's Streaming Box Has Potential, But It's No Roku, Apple Or Gaming Killer [View article]
    "These people never figured out how to set the clocks on their VCRs after 20 years, I wouldn't count on them figuring out how to voice activate their IPTV streaming devices."

    Wow, what a horrifyingly narrow-minded comment. You may want to read up on macular degeneration, glaucoma and other age-related eye issues. Fortunately for the world, Bezos apparently works on the basis of knowledge, not bigotry, and that's why Amazon is where it is and the haters are where they are.

    "You have to realize you are dealing with people with an agenda. Amazon haters that have lost money on the stock."

    Yes, look at Pokernut's comment. What the heck is he talking about? I don't own any AMZN stock. But I am a huge fan of their product.

    "There is really no benefit to Amazon's copy cat product."

    That is false. There is a MASSIVE benefit to the Amazon product. It's remote control can be voice activated. For many people, this can be a make or break issue. I'm going to order one for my mother, who can watch television but finds it extremely difficult to search for things on the visual interface.

    Actually, amazon is the only company that seems to have figured out that older people tend to have vision problems, often very significant vision problems, and that the percentage of the population in this situation is rising rapidly. Even now, the Kindle Fire product are the only ones that have special interface features for the sight impaired; magnifiers and more importantly, audio menus where you tap something and hear what it is and tap a second time if you want to make that selection.

    Contrary to what many in the seeking alpha community believe, Amazon isn't what it is because of deception or predatory practices. Amazon is what it is because they really and deeply care about their all their customers, not just the 20-something kids.

  • What Seeking Alpha Is Doing To Prevent Paid Stock Promotion [View article]

    I don't think a couple of paragraphs and a link to a boilerplate are going to suffice. Have you been reading the comments complaining of moderation, comments placed in articles by Eli that aren't even about moderation? And what's all this about appealing? The nasty-tone e-mails I've seen that have been sent regarding comment deletion expressly stated that the decisions are not appeal-able.

    Your profile shows you came aboard in 2013. I have to admit my understanding may be dated since I sharply diminished my community participation before you came aboard, having decided I didn't want to waste time dealing with what I perceived as an arrogant kindergarten. Have you changed SA's approach since you assumed your position? Perhaps the appeal situation has changed since you've come aboard. With all due respect, I think you should introduce yourself more fully -- in a separate article and not in a reply comment -- and interact with the SA community in a more meaningful way.

    I can't help but notice that many comments in response to your editorial-policy seem to be airing grievances that really address moderation. Might you persuade the head of the moderation team to post an article on SA describing their policies, and most important, participate in genuine give-and-take with readers as you've done? It's admirable the way you step up and openly discuss editorial policy, but the moderation team takes an extreme-opposite approach, preferring, it seems, to stay aloof hiding behind heavy-handed boilerplate e-mails, which obviously are diminishing the SA experience for many readers and contributors. Moderation needs to come out of hiding and follow your example.

    This is one of the most bizarre article-comment threads (an incredible example of groupthink) I’ve seen considering how quickly it comes on the heels of the recent discussion, also inspired by Eli, about pseudonymity. The sentiment there, not just on the part of Eli but, it seems, the overwhelming majority of those who commented was/is that pseudonumity is a good thing in order to foster the widest range of opinions including those who for whatever reasons are unwilling to publicly stand up and identify themselves as the authors of those opinions. I dissented strongly and maintained that in the area in which SA deals, investment ideas which necessarily address the future and, hence, necessarily deal with opinions, the author himself/herself is extremely important and that one cannot and should not separate the article from the author. As many may recall, my view was, on the whole, very poorly received in that other discussion.

    Well, folks, guess what: You can’t have it both ways. Either the author is important as an element that is separate and apart from the contents of the article or not. If you want to maintain it’s the article that counts, then why are you complaining about promoters, touts, etc. paid or otherwise? What happened to all the so-called emphasis on allowing the article to speak for itself? Goodness gracious, you couldn’t even stick to your guns for a week. If you’re all so comfortable with your ability to digest the article as a self-contained entity and use it as a starting point for your own due diligence, then why all the angst about paid promoters or even short-selling company bashers? (I shudder to imagine what SA and the SA community will look like if/when things really get hot; i.e. the market enters into a sustained downturn – SA was a lot smaller in 2008 and non-existent back around 2000-02.)

    Personally, I believe paid-promoters should not be published on SA. But that is inextricably intertwined with my belief that who the author is, what his/her experience is, what his/her motives are, what his/her level of competence is, what motive he/she may have for advocating a particular point of view, etc. are all critical. If you want to disagree with me – as many do – that’s your prerogative. But it you do want to separate the author from the contents of the article itself, then stop complaining about who is published and their motives for submitting. By your own choice, you have elected to make that none of your business.

    If you want crowdsourcing, fine, then have crowdsourcing. But you have to remember that there are a lot of bad apples in the crowd. And if SA chooses to continue to proudly advocate its support for authors who prefer to work in the shadows (i.e., pseudonymity), then you will always have a de facto welcome mat out for creeps, who, as others have pointed out, are perfectly capable of dodging IP tracking, etc. If you care about integrity, step one is to turn on the flood lights. Step two is to develop a culture wherein we DO care about WHO the author is. Those alone may not be the ultimate answer. But if you haven’t taken these important first steps, then when it comes to integrity, you’re just tilting at windmills.

  • Why Seeking Alpha Embraces Pseudonymity [View article]
    "You wrote a lot trying to legitimatize the logical fallacy known as "appeal to authority". With all due respect, you failed. Even worse, I think you're opening yourself to a lot of obfuscating noise by putting a premium on somebody's "authority"."

    That's a rather amusing comment. One of the (few nowadays) weak spots of the Seeking Alpha offering, in my opinion, is the incredible editorial tolerance for tossing Warren Buffett's name around by contributors who really have nothing interesting to say about him (and may or may not actually understand him on more than a very superficial level) or his ideas but seem to seek to confer legitimacy on otherwise pedestrian content by invoking Buffett's name.

    I'm fully aware of the so-called "appeal to authority" fallacy and what you'd have to say about it if you are taking an exam in a philosophy class. And actually, you have it wrong. The appeal to authority fallacy means the truth or falsity of a claim is not related to the authority of the claimant. But that's not what's happening here. We're not dealing with truth or falsity. This is about the future: NOBODY KNOWS - IT'S ALL OPINION. This is also about money, not philosophical discussion. Hence here, there will, ultimately, be a right and a wrong and a lot real pain for those who are wrong. Bear in mind, too, that you are taking guidance, OPINION, from a contributor you don't know and don't kid yourself about what you think you can discern from the merits of the article alone. Remember, every trade has a buy and a sell, two diametrically opposed views. (Another thing well known to philosophers.) If you don't understand where the speaker is coming from, what perspective he or she brings to bear, you're really restricting your ability to evaluate the opinions to which you're exposed.

    Suppose, for example, Contributor A writes an article suggesting stock XYZ, which plummeted badly after management cut guidance, should be sold. There are many instances in which such advice ultimately proves wise. There are many instances in which such advice ultimately proves reckless. Wouldn't you want to know the author has experience evaluating businesses such as XYZ and is likely to be able to recognize the difference between a short-term glitch and a structural problem that is likely to be longer lasting, or an eloquent amateur who is shooting from the hip rehashing ideas he picked up from message boards, CNBC, etc.?

    As to your experience with GTAT, so you got lucky on a message board. If you think you somehow "learned" something from this and now see the light, all I can say is good luck to you and those who depend on you financially. You'll need it!

    "You are imprisoned by the current MPT paradigm, maintained by PhDs, and you can't see outside it."

    Where did you come up with that drivel? This is a perfect example of the naive and self-destructive fear of professionalism. What makes you think I believe in MPT and can't see outside it? Rather than ask me what I think, you prefer to invent your own narrative to support your bigotry. And I wonder if you'd dare do something so pathetic if you were posting under your real name. For the record, I hate MPT. Back in the late '70s, my MBA thesis was dedicated to dissing it, and I'm not alone. MPT is now more widely described as an "error maximization" protocol. (I believe that term was coined by Fischer Black in the paper introducing the Black-Litteman model, an effort to try to moderate the worst of the MPT problems.)

    Look, if you prefer children or amateurs to knowledgeable professionals, don't let me stop you. It's your money. Just don't point fingers if, at some point, you find your money gone, as did so many who looked at the content and not the authors a little more than a decade ago.

    As they say, history repeats.
