The Social loop: What role does Speculative Media have?

 
Social media and influencers play a pivotal role in reinforcing the belief that a market bubble is invincible. By curating content and amplifying narratives of success, they shape investor psychology, often making it difficult to identify any of the risks until it's too late.

Barberis et al. (2018) show how investors often extrapolate past trends into future expectations, assuming that a market's growth will continue indefinitely. Social media, by selectively highlighting success stories and rapid gains, reinforces this skewed mindset. Influencers, through platforms like X, Instagram and Facebook, spread positive narratives, creating an echo chamber where investors are primarily exposed to information that supports their false optimistic view, deepening the illusion that the market can only rise and never drop.

In the works of Shleifer and Vishny (1998) they discuss how investor sentiment can be magnified through social networks. In the context of social media, influencers and media outlets can rapidly amplify emotions, especially optimism, which leads to overconfidence. By focusing on positive trends and ignoring risks, they foster a psychological loop that makes investors more confident in the market's growth and less cautious about potential downturns which in turn leads to more risk taking with consideration for any negative impacts.

In sum, social media and influencers contribute significantly to the psychological loops that inflate market bubbles. By shaping narratives of invincibility, they reinforce overconfidence, making it harder for investors to recognize the risks until the bubble bursts.
