Take this for example from VectorVest (which appears to be a good free method of gaining valuations on stocks)
CAR.AX is overvalued compared to its Price of $11.35 per share, has about average safety, and is currently rated a Buy. (26/12/15)
Update: came across this post (also on ASF) "Unlike Stock Doctor's ratings which are almost entirely on fundamentals, VV also uses technical analysis so that you sometimes see buy recommenations on stocks VV rates as overvalued and sells on undervalued stocks."
Still not sure why the inclusion of technical analysis can result in this paradox?
