If, in fact, no extensions are made, or they are for above 250,000 only, dividend-paying stocks will more than likely suffer the consequences at some point, not necessarily by year's end. An increase in rates from 15% to 43.4% (including the Medicare surtax), will make these stocks less attractive, and non-dividend payers, or high-quality growth names more attractive. Munis might be also be looked upon favorably, except for the fact that yields are so low. Mr. Market is not yet worried about any of this. Heck, there's still three months left in the year. What worries me most, beyond the deficit and fact that tax increases are but a drop in the bucket in solving it and will likely hurt economic "growth," is a scenario in which the tax rates and laws are again temporarily fixed. Uncertainty does not help matters. Uncertainty is why companies have so much cash on the books and are not hiring. This is only the tip of the iceberg in the "fiscal" cliff issue. More for another day. "Fiscal" Cliff, if you are reading this, you may want to trademark that name.
