If all goes well for nine more months, the post-financial crisis economic expansion will become the longest economic expansion in recent U.S. history. The U.S. stock markets are also on a tear, having just become the longest bull market since World War II. Regardless of your views about these trends continuing, the fact of the matter is that they are both much closer to ending than a beginning. Ray Dalio recently quantified this continuum, declaring that the economy is in the 7th inning, implying another one to three years of continuation.

While the markets can certainly keep motoring ahead, as Dalio and many others expect, there are some factors supporting the bullish case that investors should contemplate.

While this list is not by any means exhaustive, it does offer many of the most important assumptions supporting the market and some details to provide context and clarity.
