Analyzing Stock and Sector Price Momentum
by Joe Lan, CFA
In Michael Kahn’s article in this issue, “Picking the Right Stocks Using Charts,” he recommends adopting a top-down approach to investing by adding relative strength to your investment analysis. Specifically, Kahn advocates the use of charts to visually see relative strength changes rather than simply using numerical relative strength calculations.
Charts and industry strength data can be found online. The following sites are great places to start.

FreeStockCharts.com, developed by Worden Brothers, offers free “real-time” data by using the BATS exchange for data less than 15 minutes old. In addition to the usual chart plots and indicators, users can create and save their own watchlists.
Investor/RT 10.0 is one of the few investing software programs compatible with both Windows and Mac. A choice of real-time data, intraday data or end-of-day data is offered, along with standard and professional versions of each. The standard versions offer predefined technical indicators and charting tools, while the professional version allows users to perform custom scans and create custom indicators. Cost ranges from $20 to $75 per month.

Data on Sector Exchange-Traded Funds (ETFs)
Select Sector SPDRs
Select Sector SPDRs offers performance information on sector ETFs, including consumer discretionary, consumer staples, energy, financial, health care, industrial, materials, technology and utilities. These ETFs are market-weighted, which means that the companies with the largest market capitalizations will have the highest weights in the ETF; therefore, the largest companies will have the greatest influence on whether the sector and the ETF rises or falls.
Rydex SGI provides sector ETFs for consumer discretionary, consumer staples, energy, financials, health care, industrials, materials, technology and utilities. However, these ETFs are equal-weighted—that is, the largest and smallest companies are given an approximately equal weighting in the ETF. The influence of a single large company is less than it would be in a market-weighted ETF, providing a better picture of overall sector performance. On the other hand, the performance of these ETFs may differ from the performance of a similar market cap–weighted sector index or fund.
