"Sell in May and go away." Cliche but this time several other concerns as listed in this recent blog post bore out today, with all 5 main USA indexes trading below their MayPs. Indexes are still close enough to recover, so any follow through on the downside would look quite bearish.
NYA is again testing its YP so that is a very key area to watch.
There is more damage in the global indexes with ACWI moving below its YP, EEM 4/19 high on YP exact and today moving below 1HP, FXI and Shanghai weak, and oil related vehicles moving lower as well.
