Trading with the Broader Market in Mind

by Ryan Mallory

The index is price weighted and instead of being weighted using the market cap of each individual stock. That means that a company like International Business Machines (IBM) that’s share price trades over four times the amount of General Motors (GE) has four times the impact on the DJI average, even through GE trades with a much larger market cap than IBM (Market cap is defined by the total dollar value of all the shares that are publicly traded for a particular security). Therefore GE has to go up over 4% to have as much affect as IBM has on the general market.

Another Index that we do pay attention to is the Russell 1000, which is comprised of companies with much small market caps. This index tends to be much more volatile in nature, and while it is not one of the two primary indices that we trade in, we do monitor it regularly for any leading divergences that may be occurring in the general markets.

While general market direction has the heaviest weightings, when we consider to buy or sell a stock, we will not always trade 100% long or 100% short depending on the direction of the markets. In fact we will often times trade contrary to general market direction if the markets become overheated in one direction or another (best described as over-sold or over-bought). When we get these types of readings on a technical basis, they can often lead to very lucrative returns. But in essence, the balance of our portfolio will skew in favor of the market’s general direction.
