Even more on EMT, and how it applies to different strategies

Hello,

I've getting a handle on how EMT effects investing strategies now. At first I thought of it as a largely irrelevant model that really didn't make any difference to anything at all.

I noticed over time, and talking to people that they corrected me when I said something along the lines of "Investor emotions undervaluing stock prices", and said that really it's that the market has already factored in the issue or event that has taken place. I thought that that was only a bit like the cup is half full, or the cup is half empty. An identical viewpoint with a different explanation. So why would you care, if the intent is the same? It seems that you should, depending upon how you invest.

So, let me try to explain. Let's imagine that you're going to sell or buy options, all shorter term fluctuations in price cannot be gleaned from a company's financial records. Yes, some of the information will be in there, it's a good company with a great future, but there simply is not enough information to be sure where the market would be when the option expires, for example. So here we have an investment strategy that relies more on investor emotion, or EMT to try to predict where a stock will be. It's good to know the fundamentals of the company, because you may see that it's a really bad company to invest in traditional stocks with, for example. However, even that doesn't mean that you won't make money from it, it just means that you might be able to predict the direction in which the price will trend.

So, in that case, what's the alternative? Instead, it's probably better to work thinking in terms on EMT, and looking for price patterns and trends in the prices. Given the cyclic nature of stocks, it seems that you're statistically more likely to pick the correct price than looking at the fundamentals, and hoping.

Then, on the other side of the fence, there's a value investor, someone who looks for undervalued stock. That statement by itself indicates that this breed of investor is at odds with the whole EMT idea. You can't have an undervalued stock, since the price reflects the true value of the stock. Yes, I could rephrase the first statement to make it compatible with EMT, but it indicates where the investor is coming from. He's probably going to be aware of the current stock price, to see if it represents good, value, but probably isn't really interested in recent patterns and trends, since that concept is at odds with his approach.

This information may well be obvious to some readers, but I thought that I'd point it out, since the penny finally dropped, and I can now see how the land lies. I hope this helps readers understand a little more as I now feel that I do.
