“Markets don’t peak on pessimism. They peak on optimism”

There's this saying.

Does the market seem overly optimistic to you?

AAPL surely seems super optimistic. Analysts project it to have a linear path straight to $240.

More and more people are expecting new market all time highs this year. Bears have capitulated and are chasing the long direction.

Any lingering pessimism is bullish, according to this saying.

Is there anything else to be pessimistic about anymore?
