It was a pretty good week for the stock market with the Russell 2000 iShares (IWM) and the Finance SPDR (XLF) showing upside leadership for a change. IWM gained 3.21% for the week and led the major index ETFs higher. XLF gained 4.60% and was the second strongest sector (behind XLE). Even though IWM and XLF do not share any components, there is a link because financials account for around 25% of the Russell 2000. Those looking for a more direct connection should note that the SmallCap Financials ETF (PSCF) gained 4.33% last week.
