Stochastics

Mechanics of Stochastics

Stochastics in futures applications works on the principle that prices close near the top of the trading-range during uptrends and close near the bottom of the range during downtrends. Mutual funds, however, do not have a daily trading-range and they trade in much less volatile patterns. FastTrack offers a multi-day formulation of Slow Stochastics that is appropriate for fund characteristics.

Interpretation

Stochastics measures current prices compared to recent prices. Major rallies usually occur from the oversold level (below 20). Major declines usually occur from the overbought level (above 80). Use trend lines or moving averages to confirm trading points. When an uptrend breaks and Stochastics is overbought, then it is time to sell. When a downtrend breaks and Stochastics is oversold, then it is time to buy.

In the bull markets of the 1990’s, it has been virtually impossible for timing indicators to beat buy and hold returns. When a sell occurs with a particular issue, then the cash from the sale should be reinvested issues that have better technical patterns. Thus, knowing when to sell is only part of what an investor needs to know. He must also determine what to buy.

Traditional Stochastics Terms

FastTrack Stochastics has three parameters. The first is the range of days over which %K is computed. The second parameter is set to 1 unless using Slow Stochastics. The third parameter is used to smooth %K to reduce the data’s point-to-point differences.The Stochastics Chart lines are named:

  • %K – The solid yellow line
  • %D – The solid purple line

The abbreviations are sometimes preceded by a number. The abbreviation 14%K stands for %K computed over a 14-day period. The % sign notation is somewhat obnoxious since it denotes a percentage computation. Suffice to say that 14%K has NOTHING to do with multiplication by 0.14.

The yellow %K line oscillates between 0 and 100 as the price of the fund moves from the bottom to the top of its range. A purple %D trails %K.

The white dotted lines divide the chart at 20, 50, and 80%. When the yellow %K line is below 20%, the indicator is in the “oversold” condition. When the yellow line is above 80%, the indicator is in the “overbought” condition.
