I purchased shares in CAT at close to ATH prices, equating to approximately 10% of my RL portfolio.

Over the last 12 months, when the share price has dropped below $1.7 I have had a falling buy conditional order set to buy a parcel of shares equal to a third of my original parcel and then setting a rising sell conditional order to sell those shares once they rise above $2.

The reason for the sell is because I would prefer to have the dry powder to invest in other areas, rather than hold the additional shares I purchased. Further, ~10% is where I'm comfortable for CAT as a portion of my portfolio.

Is this something that anyone else does, with this company or others?
