Ugly day as the market turns over - Sell in May and Go Away they say - certainly true today. Headlines about Trump imposing Tariffs on China may be the catalyst, that old chestnut. God forbid we start following Trump's Trade Tariff Tweets around on a daily basis again. Or it may be a beginning of month thing, having locked in a great May (ASX 200 up 26% in 26 days) some institutions take today as the day to take a view on the more medium term outlook and beat the rest of the pack to the selling. Or it may be a Friday thing. Everything a bit headless. Lets take it up again on Monday. See the Strategy section for our current settings, which are wrong for a market falling 3.6% in a day. Collins Class Rule? Slap in the face noted but not reacted to. Lets see if this is a blip or a top first.
