The weak dollar is now the talk of the world. Not much different from how nobody saw the strong dollar coming. The great thing about this is if you looked at the reports from the third quarter, you were horrified to see the incredible hammering companies took and how much they guided down because of the strong dollar. Companies as diverse as Heinz (HNZ) and Hewlett-Packard (HPQ) talked about a massive swing and built in an elevated dollar amount to the 2009 numbers. This is great news if you own Colgate (CL) or Procter (PG) or Johnson & Johnson (JNJ), which are the companies that were whacked this year by three countervailing forces: 1. Strong dollar, 2. Strong oil, and 3. Consumer trade-down. The price increases put forward for these haven't kept up with the raw costs, and the dollar translation has been a nightmare. In another quarter, we will see what happens when oil annualizes strength --that is, if oil doesn't go right back up, which is something I don't take lightly given that Wrong Way Goldman is saying it goes to the $30s. (Remember when they were right all the way up?) Just the other day at P&G's analyst meeting, we heard that the numbers will be fine but that growth is slowing. I think lots of companies' growth was accelerating or at least not slowing because of the weak dollar, and we didn't care as much. When you get the dollar and oil going the right way, you can afford the inevitable trade-down in world demand and can bet that it is cyclical, not secular, because of the innovation of a company like P&G. Of course, all of this is a case of annualizing. First quarter will be a mosaic of negatives involving pretty much every input, which is why these stocks have been pummeled endlessly, not just because of hedge fund liquidation. I am cheering the weak dollar. It could be the reason there is a bid for everything from Schering-Plough (SGP), Lilly (LLY) and Merck (MRK) to Heinz and Kellogg (K). Just all good news -- provided, again, that the trend stays the same.

From a recent Mad Money show: "Yes! When you buy Wachovia, you also get Wells Fargo (WFC). You've got a winner there and I want to buy more."

From a recent Mad Money show: "I don't like these graphic chip plays. I suggest you look at Advanced Micro Devices . Nvidia's chart looks great, but their fundamentals are awful."

From a recent Mad Money show: "I like it. You've got a good one and I'd be a buyer in a slow economy."

From a recent Mad Money show: "No. I want you to avoid that. I want you to sell that one and Las Vegas Sands (LVS). You want nothing to do with those names."

From a recent Mad Money show: "No, no, no. You do not have my blessing for that business. I'm worried about Wal-Mart coming in there and taking over."

From a recent Mad Money show: "This one's under pressure, but it's the kind of company that should come roaring back. I think it'll do well."

From a recent Mad Money show: "No, no, no. If we're going to buy oils, we want oils with dividends. Consider any oil company with a dividend, like BP (BP)."
