The market bulls are still in control of things, but we all know that there is this one gigantic red flag out there that will come into play at some point. The thing is, we don’t know when that will happen, because there is no formula to tell us when it’s coming, since every bull market is different. We can look back at history as a guide, but when folks do, it doesn’t usually work out very well. The reason is simple. Nothing repeats perfectly, even though we’d like to believe it does. For instance, over the past year-plus we saw 35% on the bull/bear spread start a correction, but we also saw 46% start one.
