The stock market casino


One institution that has significant amounts of mythology and lore surrounding it operation is the US stock market. Wall Street has made many a man wealthy. These wealth generating stories are legends. What no one really talks about is about those who lose money and are often bankrupted by the same institution. In a prior post, Baseball cards as equities, I give a brief analogy describing stock trading as an ongoing auction. What is important is stocks have no value except what an individual is willing to pay and in the end, it is a zero-sum game.

As the market has been plunging over the last week and a half, it caught me by surprise on Tuesday with a sudden drop. That is the nature of the casino. I am guessing most stock owners are in a bloodbath at the moment. This gives me a chance to outline three kinds of investors on Wall Street.

Investor #1, The Insider
The insiders are professionals who either play stocks/bonds as a profession or are extremely wealthy individuals who have the inside track to corporate America. This group is the smallest consisting (guessing here) of at 0.1 % or 1 in 1000 investors. I guess they own 15-20 % of all stocks and bonds though. This group will always make money in the end because they have the knowledge and power to manipulate individual stocks. Insiders know when a big time news event is going to happen even before a public announcement. One fictional character who fits this category is Gordon Gecko in the 1987 movie Wall Street. The majority of all profits reside in this elite group. We define this group as
those who know what is occurring.

Investor #2, Experienced, Successful Traders
This group of traders do not have the inside track as The Insiders do, but they have an idea of how Wall Street works. This group consists of smart hedge funds, individual traders and those at big bank trading groups. They consist of about 10 % of all investors. They probably have 15-20 % share in total assets. This group makes money most of the time. Since they lack advanced insider knowledge, they also lose on many trades. One subcategory of this group are high frequency traders (HFT). This subgroup uses high speed supercomputers to beat the market. What is even more interesting, HFT represent ~80 % of all trades made on the New York Stock Exchange. HFT are what control the majority of stock movement in modern stock exchanges. We define this group as
those who know that they do know what is occurring.

The initial two groups outlined above are known as the smart money. They make money off of stocks and bonds. Who do they make money from? The following group, the dumb money.

Investor #3 Retail Investors and Inexperienced Traders
This group of traders represents the majority of investors. It includes all of those who put money into mutual funds, 401ks, IRAs, day traders (yes, day traders) and the majority of part time traders. This largest group of investors is fed the normal "fundamentals" and "over the long run stocks are the best investment" advice. Unfortunately, this is not the case because the stock market does crash. Crashes wipe out a significant amount invested in this group. As I previously stated, stocks are worth only what someone is willing to pay and they do not have an intrinsic value. The "fundamentals" advice is just smoke and mirrors to convince the average Joe to invest. Smart money knows these stock truths and avoid crashes. The lost dumb money proceeds ends up going to the smart money. We define this clueless group as those who don't know that they don't know.

Driving with the rearview mirror




One source of continuous fascination is the stock market. Why not? Put in a little money, it grows, and in the end profit without labor. How can you not like that! Billions of dollars is exchanged on the world's stock exchanges daily. Stock markets exist as an easy way for companies to raise money through a collective public ownership. Of course, the market operation is much more complex.

The psychology behind this money for nothing concept supports the main market drivers, fear and greed. Everyone who has struggled to make a dollar and put it into an online brokerage account understands this. They love when the market goes up and make money. Optimism pushes buying, the market rises. They absolutely hate when the market goes down with money evaporation. Pessimism leads to selling, the market craters. In the end, the market is a sentiment machine driven by the various kinds of investors summarized by this site.

Excluding day traders, two main kinds of investors exist: fundamentals and technical. Fundamental trading is based upon the idea that a stock is worth a certain value according to corporate size and revenues. Profitable companies are worth more than unprofitable entities. The other investors are technical traders and their trading is dependent upon derived indicators. Some of the best known indicators are:
Moving Average Convergence-Divergence (MACD)
Fast and Slow Stochastics
Relative Strength Index
Bollinger Bands.
The basic concept behind all of these indicators is to identify the point at which a stock changes momentum, i.e. stops going down in price and begins to appreciate.

The movement of the markets has thousands of traders everyday bidding prices up and down. Buying and selling stock. One school of thought has stock market movement being random. Looking over years of stock market data, patterns appear. Typically in upward movements followed with an occasional sell off forming a wave pattern. Personally, I believe the day-to-day patterns are random, but over time patterns do exist. Technical trading is supposed to clue an investor into these patterns identifying momentum changes. Honest traders admit they are lagging indicators or tools that tell investors when to buy (or sell) after the momentum has already changed. I agree, but another serious issue that is a fly in my ointment is these indicators all use
past data. What happened yesterday, may not necessarily happen tomorrow. Yes, the indicators show stock price going up. If another disaster like 9/11 hits New York, will the indicators show this. NO!!!!!! As we discussed earlier, the market tends to be a sentiment indicator. One frustrated mutual fund manager has heart burn from his favorite Indian restaurant may drive down a stock. The indicators will not pick this up until it is too late. I think the best analogy is driving down the road using the rearview mirror instead of looking through the windshield. That crash ahead is pretty rough.
