There are many s question around tool-tip positioning on StackOverflow ,The way I used in my chart was to show tooltip left or right on hover of column using positioner.

 tooltip: {
   positioner: function(labelWidth, labelHeight, point) {         
                         var tooltipX, tooltipY;
                            if (point.plotX + labelWidth > this.chart.plotWidth) {
                                tooltipX = point.plotX + this.chart.plotLeft - labelWidth - 40;
                            } else {
                                tooltipX = point.plotX + this.chart.plotLeft + 40;
                            }
                            tooltipY = point.plotY + this.chart.plotTop - 20;
                            return {
                                x: tooltipX,
                                y: tooltipY
                            };       
                    } }
