Why the Costa Group share price (ASX:CGC) is crashing this morning

The market is holding on to recent gains but the big rally in the Costa Group Holdings Ltd (ASX: CGC) share price came to a jarring halt after it was downgraded by a leading broker.

The CGC share price tumbled 5.6% to $4.05 in early trade when the S&P/ASX 200 Index (Index:^AXJO) is trading a little under breakeven.

This makes the Costa share price the worst performing stock on the ASX 200 at the time of writing. The fruit and mushroom grower is the only non-gold stock on the worst losers list.

The Resolute Mining Limited (ASX: RSG) share price and Gold Road Resources Ltd (ASX: GOR) share price are in second and third positions.
