Retail traders just made history.
Friday's market selloff triggered over 108 million options contracts traded. That's the biggest options volume day ever recorded. Only the second time trading topped 100 million contracts.
Here's the surprising part: retail investors weren't panicking. They were buying.
Scott Rubner from Citadel Securities noted that retail traders showed an 11% bias toward buying calls (bullish bets). That's way above the 4% average from the past three months.
It was the single largest day of call buying the platform has ever seen.
Even more striking? This marks the 24th consecutive week that retail traders showed a "better-to-buy" sentiment. That ties the longest bullish streak ever recorded.
Charles Schwab reported similar trends. Daily trades on their platform jumped 30% in the third quarter compared to last year. The surge helped them beat earnings expectations.
Something unusual is happening in the stock market.
Traditionally, hedge funds and big institutional investors were the "smart money." They led market movements. Retail traders were the chasers who bought late and sold at bottoms.
That's flipped this year.
Hedge funds declined to buy Friday's dip. But retail traders jumped in aggressively.
Bank of America and JPMorgan both noted that institutional investors are de-risking. They're getting more cautious and selling. Meanwhile, everyday investors keep buying.
And here's the kicker: the retail traders have been right.
The S&P 500 is up nearly 2% this week after Friday's selloff. It's powered through negative headlines about tariffs, geopolitical conflicts, and economic weakness to hit all-time highs.
The "buy-the-dip" mentality from retail investors has essentially held the stock market up all year.
Small investors are now driving equity prices in a way they haven't before. Their conviction remains "extraordinary," according to Rubner.
But there's a flip side.
When everyone is bullish and buying dips, markets can become vulnerable. If retail sentiment suddenly shifts, there might not be enough big institutional buyers to support prices.
Retail investors are showing incredible confidence right now.
Record options volumes. 24 straight weeks of bullish buying. A willingness to buy dips that professional investors are avoiding.
So far, this strategy has worked. The market keeps climbing despite plenty of reasons to worry.
But it's worth noting what's different here.
Usually when hedge funds back away while retail piles in, that's a warning sign. It often meant the little guy was getting caught holding the bag.
This time feels different - at least so far. Retail traders have correctly called the market's resilience through multiple scares this year.
Citadel's Rubner says he's still optimistic. He thinks seasonal strength in November could push stocks higher. But he also cautioned that investors should be careful over the next few weeks.
For everyday investors, the key question is whether this retail-led rally can continue.
Options trading volumes at record highs show extreme conviction. But extreme conviction can cut both ways.
If you're participating in this rally, recognize that you're part of a historic shift. Retail traders are leading, not following.
That's empowering. But it also means there's less of a safety net if sentiment changes quickly.
The "buy-the-dip" mentality has been rewarded consistently this year. Just remember that every winning strategy eventually stops working. Often right when everyone believes it never will.
