We began the fourth quarter with overweights to energy, services and telecommunications, and underweights to consumer products, building materials and restaurants. We ended the quarter with overweights to energy, cable television, gaming and services, and underweights to broadcasting, consumer products, steel and diversified media.Outlook Fundamentals in the high yield market remain generally solid, with sound corporate balance sheets and manageable financing requirements. We continue to look for warning signs, such as increasing leverage, weaker earnings and deterioration in the quality of underwriting standards. Primary market activity was particularly robust in 2012, as corporations sought to take advantage of the low-rate environment amid strong demand for high yield bonds to refinance outstanding debt. As most high yield companies currently have limited refinancing needs, the risk of a spike in defaults from their current low levels is limited. While we expect defaults to remain below historical averages, lower quality issuers could be susceptible to persistently slow economic growth or a macro shock. Throughout the year we saw spreads tighten leading yields toward historically low levels. While the potential for a degree of further spread tightening based on technical demand remains, periods of heightened volatility could be triggered by political, macro or economic challenges. In our view, despite relatively low yield levels, investors remain more than compensated for default risk, although trading liquidity remains poor by historical standards.
