But before de-camping for the summer months, investors is 5.7%), the S&P 500 has traded on a trailing price should consider the following: earnings ratio of 20.1x. • A "sell in May" strategy would have historically proven • Record highs tend to be supportive of, rather than costly. returns are indeed lower in the detrimental to, near-term returns.

We expect the expansion and bull market to continue for some time, and recommend a risk- on positioning. But it's also important to manage downside risks. We recommend a tactical overweight to long-duration Treasuries as a part of this protection and, looking beyond our 6-12 month tactical horizon, our Bear market Guidebook also provides insight on structural and strategic ways to protect against the next downturn, when it appears. • Grow.
