The blog Long or Short Capital is often hilarious, and sometimes it can be quite informative. At its best, it's both. Its recent post outlining 11 signs of a market top is a pretty awesome read (reason #4: Dog Yoga). What really caught my eye was this chart of Sotheby's. The perfect alignment between its peaks and the economy's peaks is quite something (and worrisome) to behold. Nobody's suggesting that you can make a real conclusion just by looking at one stock, but it is something to store away in the thought bank. It also gives a bit more color to the recent record-breaking art auctions.
