As long this stock has Santander in its name and is majoritarily owned by STD and not included in ETFs portfolios, it will underperform its more expensive and not really more profitable competitors.
I am unable to guess when this unsustainable trend reverses and it may take decades. It is just incredible how fundamentals have no importance in investment performance except for the fact that an insolvent company is worthless. Beyond that, all is trend based and popularity crowd herd following. In short, the less you know, the less error prone you are since you have nothing to rationalize failing choices and/or are more likely to stay away from any stock at all and staying away from stocks is the heck of the best strategy for last decade.
