**Smart investor say that average up in investment**. But my calculation shows bad results.

Let us say I am following simple method of regular investment in rising stock at 20% interval with stop loss of 16.67% i.e.

time-1: Buy 1 unit at price 100

time-2: Buy 1 unit at price 120: Now 2 units at average price 110 with profit of ~ 10%

time-3: Buy 1 unit at price 144: Now 3 units at average price 121 with profit of ~ 20%

time-4: Buy 1 unit at price 175: Now 4 units at average price 135 with profit of ~ 30%

time-5: Buy 1 unit at price 210: Now 5 units at average price 150 with profit of ~ 40%

time-6: Buy 1 unit at price 250: Now 6 units at average price 166 with profit of ~ 50%

time-7: Buy 1 unit at price 300: Now 7 units at average price 185 with profit of ~ 62%

Now if we hit Stop loss at 250 then 7-units * [Buy@185 and Sell@250] => Profit of 35%

Now if we hit Stop loss at 210 then 6-units * [Buy@166 and Sell@210] => Profit of 20%

Now if we hit Stop loss at 175 then 5-units * [Buy@150 and Sell@175] => Profit of 16%

Now if we hit Stop loss at 144 then 4-units * [Buy@135 and Sell@144] => Profit of 6%

Now if we hit Stop loss at 120 then 3-units * [Buy@121 and Sell@120] => Profit of 0%

Now if we hit Stop loss at 100 then 2-units * [Buy@110 and Sell@100] => Loss of 9%

Now if we hit Stop loss at 83 then 1-unit * [Buy@100 and Sell@83] => Loss of 17%

So “**average up in investment**” also not that fruitful OR am I missing something here ?
