Look for the company Cyntegra in Idexx's News announcements, and what is in progress legally since the 2Oth of September.
Then look up on the net about the owner of Cyntegra, Simon Brodie, and what kind of a person his is. Then you'll see why the stock is see-sawing everyday - the big dogs are waiting for a judge to make a call.
For chartists, the trend clearly shows a break in a quite impressive 3-4 month run. These patterns are quite predictable; once the trend has been broken, the price tends to fall sharply as longs exit, and shorts pile in. Chart patterns are definitely not a bullet-proof investment method, but then again, none are.
Perhaps the end of day failures we are seeing is a reflection that investors are now seeing more downside than upside potential in the days and weeks ahead? Certainly many folks are now deciding to lock in profit after a very good run.
It seems right to be suspicious of a stock that cannot hold on to its gains, especially on a day like yesterday when the broader market gave up very little at the end of the day.
