// Product model
public function stockValueSum()
{
    return $this->hasMany('Stock')->sum('value');
}

then

Product::find($id)->stockValueSum();

will return sum of related 'value' columns on 'Stock' model's table

Mind though that you can't eager load this value with the above method. For doing this you would have to do some join
