Is the company in bad shape?

The company's share price has lagged far behind that of APT. APT has a huge advantage in the market.
We know that the growth rate will decline as the company gets bigger, but the SZL is so much smaller than APT, but the growth rate of the SZL is not so much faster than APT, so how can the SZL compete with APT?
The SZL also seems to charge merchants more than APT, so I can't see how the SZL can survive in the market.
