Nice price close for POS

At the risk of sounding like a scratched record here (giving away my age a bit) I am still scratching (!!) my head over JS's sell recommendations last week on WSA and POS. WSA are already 20% higher and POS 15% on today's close, than the timing of those recommendations. This ISN'T a hindsight thing....
Strikes me - at times like this, even the experts can be SO BLEAK in their expectations, a satisfactory low price "can never be reached". Probably the loudest alarm bell to everyone, to BUY, when that last sell cry is heard.
