Gamma Squeeze – The Hidden Force Behind Sudden Price Spikes

1. What Is a Gamma Squeeze? A Gamma Squeeze occurs when market makers or institutions who sold call options are forced to buy the underlying stock to hedge their positions as the stock price rises. This creates a feedback loop, pushing the price even higher, often unnaturally and rapidly. It’s a chain reaction set off by options trading, not fundamentals or news. 2. Understanding the Mechanics • When someone buys call options, the seller (often a market maker) becomes short gamma. • To remain delta-neutral, the seller must buy shares as the stock price approaches the call’s strike. • If many call options exist at nearby strikes, this hedging activity drives up stock demand, hence price. • This rise triggers more buying, as the price crosses new strikes—this is the “squeeze.” 3. Famous Examples • GameStop (GME) in 2021 • Tesla during several rallies • Adani stocks post-2022 saw speculation of such behavior In each case, massive call buying at OTM strikes forced institutions to hedge aggressively, fueling the price rally. 4. Clues That a Gamma Squeeze May Happen • Unusual OI buildup in short-term OTM call options • Stock trading near large call open interest levels • High implied volatility and low float stocks • Social media or retail hype entering the narrative • Sudden jump in volume with no major news 5. How Traders Use This • Speculators try to front-run gamma squeezes by spotting heavy OI in weekly call options • Hedgers monitor gamma exposure to avoid being caught on the wrong side • Retail traders sometimes unknowingly trigger one during mass call buying in speculative names 6. Conclusion Gamma squeezes aren’t just meme stock phenomena—they represent a powerful force in options markets. Understanding them allows savvy traders to spot opportunities early or avoid dangerous traps during speculative rallies.
