GUEST COMMENT: I am channelling Ayn Rand to help determine my career path

The Russian-American novelist and philosopher Ayn Rand argues that all of us have a philosophy of life. Likewise, when it comes to investing, I think it's really good to know what you believe and how you know it to be true. Successful investing requires a unique blend of attributes and ideas. A humble spirit, for example, allows investors to learn from their own mistakes and also from others.

"I'm not proud," veteran investor Jim Rogers once shared with me candidly. "I try to buy anything I can find which is low, where positive changes are ahead." Of late I've been doing some soul searching about my own investment approach.

Having invested for years, I would stress the importance of having a philosophy. It's like the rudder on a ship that has to stand up to the test in both calm seas and choppy conditions. Without a guiding compass, you will be switching aimlessly from one investment strategy to another.

As I contemplate a move into the investment management field after my Masters in Finance from London Business School, it's important for me to be able to articulate coherently my core set of beliefs, and the way I think about markets and how they work.

If you read the writings of the investment greats, you detect deep philosophical and methodological differences in the likes of Buffett, Templeton and Lynch. For example, Peter Lynch and T. Rowe Price both invested in growth companies, but they also approached the market in subtly different ways.

Price focused on well-managed companies in fertile fields, whose earnings were expected to grow faster than inflation and the overall economy. Discipline and process consistency drove his investment philosophy. Fidelity legend Peter Lynch sought out "multi baggers", but he also pioneered a hybrid of growth and value investing, or what is referred to as a "growth at a reasonable price" strategy.

I've heard some job seekers say that one should be flexible when choosing which investment management firm to apply to. They favour carpet-bombing CVs to as many firms as possible and argue that one can simply blend one's investment beliefs with those of the new employer.

I see their reasoning given this moribund employment market, but this is where I channel Ayn Rand: your philosophy is either conscious, explicit, rational and practical, or it is unconscious, random, unidentified and, therefore, impractical. Suppose your investment philosophy is radically different from that of your target firm, won't you be miserable? After all, how much can you compromise, given your objectives, tolerance to risk and personal characteristics?

    There isn't an algorithm!! It's not a pure SCIENTIFC calculation. Said company has this debt to earnings ratio, and this historic growth rate bla bla

    He's loking at management strategy too, what edge the business has over its rivals, bla bla..An artistic element.

    You wouldnt be able to produce an algorithm that would replicate his buys, and when he sold etc etc..

    And for that reason your point is dismissed.

    @Whiz - sadly connecting the dots you have provided does not give me the definition of "skew distribution" but rather a "skew normal". My original point from which we have digressed substantially is that the returns of all of the so-clled investment greats that guest has provided are negatively skewed and amount to no more than picking pennies up in front of combine harvester. One day, you will get put in a haystack. The fact that it hasn't happened to Mr Buffet yet is not a refutation of the assertion but simply a matter of probability. Mr Buffet might sadly pass away before it happens to him but if we created the Buffet alorithm which encapsulates the Benjamin Graham school of investing then sooner or later that algorithm is going to blow up.

    Come on Desai thought you'd be able to connect the dots by now? High flier like you..

    skew distribution, I.e. a distribution with skew. Where we would think of a normal distribution as being symmetric, a distribution with skew will be one where the mean does not equal the median.

    Charlie says so? PLease read up on the matter and provide a full, I want assets, debt, potential growth, earnings, management strategy, competitors..And I want you to tell me what value you come to, and then tell me if its greater than or less than Spot, and then I wil explain to you if it's a buy or a sell..Surely you can at least provide that, given I have provided you the details of your skew distributions.

    @Whiz - thanks for providing a definition of "the skew normal" distribution. I await the definition of "skew distribution" that is really useful in finance.

    Tesco is a sell btw... Charlie says so.

    In probability theory and statistics, the skew normal distribution is a continuous probability distribution that generalises the normal distribution to allow for non-zero skewness.

    Now you tell me, whether Tesco is a buy or not. I want you to use Ben Graham's principles.
