Nyse Price Quotes

As they worked through the order types, they created a taxonomy of predatory behavior in the stock market. Broadly speaking, it appeared as if there were three activities that led to a vast amount of grotesquely unfair trading. The first they called “electronic front-running”—seeing an investor trying to do something in one place and racing him to the next. (What had happened to Brad, when he traded at RBC.) The second they called “rebate arbitrage”—using the new complexity to game the seizing of whatever kickbacks the exchange offered without actually providing the liquidity that the kickback was presumably meant to entice. The third, and probably by far the most widespread, they called “slow market arbitrage.” This occurred when a high-frequency trader was able to see the price of a stock change on one exchange, and pick off orders sitting on other exchanges, before the exchanges were able to react. Say, for instance, the market for P&G shares is 80–80.01, and buyers and sellers sit on both sides on all of the exchanges. A big seller comes in on the NYSE and knocks the price down to 79.98–79.99. High-frequency traders buy on NYSE at $79.99 and sell on all the other exchanges at $80, before the market officially changes. This happened all day, every day, and generated more billions of dollars a year than the other strategies combined.

2. Don’t trade penny stocks. A penny stock is any stock that trades under $5. Unless you are an advanced trader, you should avoid all penny stocks. I would extend this by encouraging you to also avoid all stocks priced under $10. Even if you have a small trading account ($5,000) or less, you are better off buying fewer shares of a higher-priced stock than a lot of shares of a penny stock. That is because low-priced stocks are most often associated with lower quality companies. As a result, they are not usually allowed to trade on the NYSE or the Nasdaq. Instead, they trade on the OTCBB ("over the counter bulletin board") or Pink Sheets, both of which have much less stringent financial reporting requirements than the major exchanges do. Many of these companies have never made a profit. They may be frauds or shell companies that are designed solely to enrich management and other insiders. They may also include former “blue chips” that have fallen on hard times like Eastman Kodak or Lehman Brothers. In addition, penny stocks are inherently more volatile than higher-priced stocks. Think of it this way: if a $100 stock moves $1, that is a 1% move. If a $5 stock moves $1, that is a 20% move. Many new traders underestimate the kind of emotional and financial damage that this kind of volatility can cause. In my experience, penny stocks do not trend nearly as well as higher-priced stocks. They tend to be more mean-reverting (Mean reversion occurs when a stock moves up sharply from its average trading price, only to fall right back down again to its average trading price). Many of them are eventually headed to zero, but they are still not good short candidates. Most brokers will not let you short them. And even if you do find a broker who will let you short a penny stock, how would you like to wake up to see your penny stock trading at $10 when you just shorted it at $2 a few days before? I learned that lesson the hard way. It turned out that I was risking $8 to make $2, which is not a good way to make money over the long term. To add injury to insult, a penny stock might appear to be liquid one day, and the next day, the liquidity dries up and you are confronted by a $2 bid/ask spread. Or the bid might completely disappear. Imagine owning

detect a market top, keep a close eye on the daily S&P 500, NYSE Composite, Dow 30, and Nasdaq Composite as they work their way higher. On one of the days in the uptrend, volume for the market as a whole will increase from the day before, but the index itself will show stalling action (a significantly smaller price increase for the day compared with the prior day’s much larger price increase). I call this “heavy volume without further price progress up.” The average doesn’t have to close down for the day, but in most instances it will, making the distribution (selling) much easier to see, as professional investors liquidate stock. The spread from the average’s daily high to its daily low may in some cases be a little wider than on previous days.
