Prices are holding up on all classes as far as I can tell. I only have market reports to refer to on several classes, but I have sold heavy bills for close to $2/lb., and cull cows for north of $1.50. And I just sold a load of 5 weights that included several heifers that averaged $4.03/lb across the whole load. That's pretty spectacular. I'd say cancelling consignments has a bigger chance to end negatively than positively.
Heck $10-$15 cwt is nothing in today's market, and can happen simply according to which buyers are present that day. Obviously we want every dollar possible for what we sell, but I'm saying that I would have been doing fine with a $50cwt swing either way. $3.53 cwt is almost hard to believe and that's $50 less than what I got.
I think sometimes we forget where we started, $1.40-$1.50, and get desensitized and greedy when prices get to these levels.
Bottom line, if you got em, sell em. They gonna do good and you're gonna make money.
