Company's with increasing profit margin over time

Been playing around with trends. I wanted to see companies on an exchange that had increasing profit margins over time. I want to try and 'catch' one of the rising stars before the become famous, so to speak.

code	exchange	r2	latest_pe_ratio
MHO	US	0.8684408011742693	6.1047
TMHC	US	0.805919804849865	7.3865
PHM	US	0.8328457609967387	7.7232
GRBK	US	0.9033258205909432	7.8133
PLBC	US	0.8550728429971046	9.596
LEGH	US	0.9574886382293258	10.4672
OTTR	US	0.9595809424062113	11.3519

• MHO has been around a while but revenue and net income are on the way up
• Same with THMC.

Investigating other stonks is an exercise for the reader.

I've also played around with finding companies with increasing dividend yield, profits over 'n' % per year for the last 'x' years.

More detail

The closer r2 is to 1 the better the trend line.

I calculated the profit margin for every company on an exchange for their entire history. Then I filtered only those companies that had a trend line that was increasing.

I then excluded those companies where the latest PE ratio was above 12.
