If we think UPST will be a much larger company over next few years, I would prefer to stay put in UPST, and even add on further weakness, the reason is: 1)Under current market condition, not a raging bull market, it is highly likely we may move to a stock which could drop even more; 2)we may be so scared at the bottom and not to add UPST back, and we could miss another Shopify or Amazon over long run.
Just my thought.
