Have you noticed? Stock markets (globally) keep rising. Surely, earnig reports look good for now, but at the same time the consensus arises that for the next year the outlook is far less optimistic. Numerous macro economic factors starting to "sink in".
Could it be, that investors are in a mode "to miss out on something", thus keep buying, regardless of other considerations?
If that should be the case, this is usually a good sighn that long lasting bull markets are near their peak.
On the other hand, I would be glad to hear of future concepts that would assure that the current bull market will never end.
