Equity Curve:

Since 1986 May has not really deserved the reputation it has gotten. It has not been a great month, but for the last 20+ years, it has been a fairly consistent (if small) winning month.

If historical patterns prevail, this May will be a month to consolidate the gains of the past few months.
