Warren Buffet's firm Berkshire Hathaway Inc. took a new 10-million share stake in General Motors Co. in the first quarter. That's worth approximately $214 million as of Tuesday am ($21.42/sh). We all know Buffet's opinion on PM. So let's see what he could have bought with that money instead of paper: 7756433 oz of silver or 138817 oz of gold at the common man's spot price. Now I know he's not buying GM for short term gain. And it will be almost impossible to track when he sells off his holdings so a direct comparison of profits vs. PM is impossible. But it will be interesting to see how GM stock does vs. PM for the next 6 months, 1 year... and so on. I've never understood why he has such a negative opinion of PM.
