"Market greed is rising" or "Increase in market greed".

In financial markets, "greed" is a key concept. It represents the desire of investors to achieve greater and faster profits. An "increase in greed" could refer to a situation where:

* Asset prices (such as stocks or cryptocurrencies) are rising rapidly, driven by optimism and euphoria among investors.

* Investors are taking more risks than usual, often buying overvalued assets out of fear of "missing out on profits" (FOMO - Fear Of Missing Out).

* The market is becoming very speculative, with buying decisions based more on emotion than on solid fundamental analysis#MarketGreedRising
