This ETF offers targeted exposure toward the U.S. consumer staples sector, making it a potentially useful tool for those employing a sector rotation strategy or for investors looking to tilt their portfolio towards a low beta sector that can perform relatively well in down markets. PSL is one of the "Dynamic" ETFs offered by PowerShares, meaning that the underlying index utilizes a quant based analytical framework to select holdings. In exchange for this attempt to generate alpha, investors can expect to pay a bit more; PSL is more expensive than FCD and XLP. For those who believe the Intellidex methodology has the ability to add value, PSL might be an interesting play (First Trust's FXG also utilizes a quant-based methodology within this sector). But considering the less-than-impressive track record and expense differential, there are probably better ETF options for exposure to this sector.
