Goldman Sachs' chief investment strategist Abby Joseph Cohen on Monday raised her recommended equity weighting to 75 percent from 70 percent and cut her bond weighting to 22 percent from 27 percent. 

Stocks are more attractive than before because they are undervalued and because of government initiatives intended to reduce the duration of economic dislocations, Cohen wrote in a note to clients. 

Stocks are also attractive because of corporate share repurchases, cash on the sidelines, and confidence stemming from the resilience of the banking system and smooth reopening of the public markets following the attacks of September 11, Cohen wrote. 

Cohen maintained a 3 percent weighting in commodities while keeping cash at zero.
