A lot of definitions are useless. Defining a piece of crap as a piece of crap doesn’t make it smell any better. Defining a correction as a 10% reduction off the previous high is useless and doesn’t make it feel less painful. Maybe some people were impressed that the July-August-September market corrected 10% and then bounced. Okay - excuse me but what do you do with that? Do you hold all the way down and then start buying the index the moment it hits 10% believing that the worst is over? Not me. In fact, I have no idea how to use this information. If the decline is 8%, I have no expectation that is almost sufficient. 10% is not a magic number. And while we are at it, let’s discuss the definition of a bear market - commonly recognized by a price decline of 20% from a recent high in an index over a 12-month period. So what? Does it help you to avoid losing money when they define that your loss is now roughly worth two consecutive 10% corrections?
I look at each stock on its own merits. When the chart looks toppy and the technicals crumble, I change my signal to down. When the fundamentals are saying the stock is fully, highly or over valued, I change my signal to down. I have no bias as to what percentage a stock had to go up before I was impressed it went up. Up is Up. Down is Down. I would never say …”that stock just declined 10% off its record high, let me buy bunches of it” - just as I would never say..”that stock just appreciated 10% from its bottom so I need to sell it.” I hope you would never say or do something that stupid either. Movements in stocks are much too complicated to rely on basic percentages.
For some reason however, people are willing to buy into that idiotic concept about the market as a whole, as defined by an index. And what is so amazing about all this is that market indices are much more complex than individual stocks. In this world of too much program trading, of too much quant modeling and synchronicity, of too much media coverage, of too much hedge fund capital, of too much indexing and index ETF trading, of too much manufactured market technical analysis and of too much other bullshit, we are subject to defining our investing and trading with definitions.
It seems to make it easier for people or at least comforting to be able to give something a name. Psychologically - most people are FINITe and as a result, they love (you guessed it) deFINITions. It’s much tougher to keep our minds open to the undefinable - the vague concepts like space and time - without knowing where we are and how long until we get to wherever. Defining a 10% loss as a correction is not helpful. Defining a 20% loss as a bear market is not helpful. For the very same reason, I didn’t define the point of my most recent bearish bias on 10/22/07 as the beginning of a correction. At best, it was a guess about a direction towards a place I cannot define and over an indefinite concept of time. I have a good sense of direction, the rest I leave up to the market to determine.
