For sure! Stocks have "behaviors". That one looks like a clear trait.View attachment 237839 After seeing mskl's post, I looked at a chart for KELYB. Seems the same sort of think happened August 11, price went from 18-78. so, unless you do absolutely no digging before you buy into a position, you would have had adequate warning that it COULD happen, because it HAD happened, less than 2 weeks ago.
Stops, man, stops. Don't leave home without them.
