IMO- You have to consider market timing. 2017 the economy had been to hell in a hand basket, healthcare / med was a largely impacted sector. Amazingly, RNVA hung on and weathered all of it.
If you want to take this viewpoint waaaaay back to the market crash of the 80's - those investors who "held on" and did not panic eject- are now very wealthy. A majority of those companies survived via various methods - recovered with the economy - and went on to large growth.
