I've heard the double bottom argument.
I'm not a technical analyst. I can tell you that the levels we see today are entirely disconnected from reality for two reasons. First, the "E" in "P/E Ratio" is wildly overestimated for 2009 and beyond. Second, we have only just begun to see the tip of the iceberg on "securities" exposure across the markets, as we saw with GE today. Looking out 12 months, these market levels are going to look more like the Nasdaq bubble in 1999 - 2000. The basic valuations of almost all sectors, with the possible exceptions of energy, agricultural producers, and mining firms, is extremely optimistic.
Finally, price the stock market in something besides the US dollar. Look at it priced in Euros, Canadian Dollars, or gold. Price it in wheat. Price it in oil. While we may be seeing some "channel" for the nominal value of where the Dow Jones averages are, the real purchasing power at 12,500 or 13,500 isn't the same as it was just two years ago, never mind five or seven years.
Holders of US equities are losing value every day with the plummeting US dollar. It's time to get out of the US market, and US dollars.
