The following commentary comes from an independent investor or market observer as part of TheStreet's guest contributor program, which is separate from the company's news coverage.NEW YORK ( Options Trading Signals) -- Members of my service are used to seeing analysis about the Russell 2000 Index on a daily basis. Every day I monitor the price action in the iShares Russell 2000 Index ( IWM), the iShares Dow Transport Index ( IYT) and the Financial Select Sector SPDR ( XLF). Quite often one, if not all, of these ETFs start throwing off clues about Mr. Market's favored direction. During strong moves in the market, all three ETFs generally will move in the same direction regardless of whether prices are going up or down. If the move is strong and has momentum, all three will move the same way, but one generally will display relative strength against the others, and against the S&P 500. Recently the Russell 2000 Index started showing signs of life, and then the transports and financials followed the small-caps higher. Although both the iShares Dow Transport Index (IYT) and the Financial Select Sector SPDR (XLF) traded higher in recent days, neither had the relative strength that the Russell 2000 ETF (IWM) had. When the small-caps speak, I listen, and they have been screaming that higher prices may be likely next week and into the first week of June. However, as the daily chart of IWM below illustrates, they had some major work to do the rest of Friday and next week.
