Meme Stock
A stock that becomes a hot topic on social media and online communities, drawing crowds of individual investors and surging regardless of its earnings.
Meme stock = a stock that swings sharply on social media buzz and crowd psychology rather than fundamentals (earnings/financials)
They show extreme volatility — surging when the buzz explodes on social media, then dropping sharply when interest cools or the mood turns.
In plain terms
A meme stock is a stock that surges because it becomes a hot topic on online communities (Reddit and the like in the US) and social media, drawing individual investors in droves — regardless of the company's earnings.
GameStop and AMC in 2021 are the classic examples. A mood along the lines of "let's all buy together and stand up to the short sellers" spread through social media, and the share prices shot up. It was word of mouth and crowd psychology, not fundamentals, that set the price.
What it tells you
Meme stocks show, in an extreme way, that a share price can move on attention and sentiment rather than value. It's a new phenomenon: in the social media era, individuals gathering together can shake the market in the short term.
But a price driven up by word of mouth deflates quickly once the attention fades. Meme stocks rise on mood, not on earnings.
Formula
Meme stock = a stock that swings sharply on social media buzz and crowd psychology rather than fundamentals (earnings/financials) (GameStop and AMC in 2021 are the classic examples)
What high or low means
They show extreme volatility — surging when the buzz explodes on social media, then dropping sharply when interest cools or the mood turns.
Because the surge comes from sentiment and supply-demand rather than fundamentals, the price often moves far apart from the company's value, both on the way up and on the way down.
A meme stock's surge often isn't the result of improved company earnings. A price lifted by word of mouth rests on weak grounds and can deflate in an instant, and those who came in at the very end are hit hardest. (This is an explanation of the concept, not a trading suggestion.)
Meme stocks are where FOMO — the "everyone else is making money except me" feeling — works most powerfully.
