Costco (COST) Options Signal: Heavy Put Wall at $750 Clashes with Bullish Sales Data

• COST opens higher at $959.55, up 1.17%, testing resistance near the $966 intraday high.
• Options market shows extreme caution: Put/Call Open Interest ratio stands at 1.29, signaling significant downside hedging.
• A massive $750 Put wall dominates short-term sentiment, creating a strong psychological floor for bears.
• Despite strong July sales growth (+10.7%), technicals show a short-term bearish engulfing pattern, suggesting a potential pullback before any sustained rally.

It’s a classic case of two narratives colliding. On one side, you have Costco’s relentless operational momentum. On the other, an options market that seems to be bracing for a fall. If you’re looking at COST today, Aug 6, 2026, the price action might look strong, but the derivatives market is whispering something else entirely. Let’s break down what’s really happening under the hood.

The Heavy Put Wall and Sentiment Disconnect

Let’s talk about the options chain, because this is where the real tension lies. The total Put/Call Open Interest ratio is sitting at 1.2878. For those who don’t track this daily, that means for every call bought, more than a put is being held. It’s a bearish signal, or at the very least, a deeply cautious one. Traders are paying up for insurance.

Look at the expiration data for this Friday, August 7. The most significant open interest for puts is clustered at the $750 strike with 2,077 contracts. That’s a huge wall. It’s far below the current price of $953, which suggests these aren’t just day-traders speculating on a crash tomorrow. These are institutional players hedging against a mid-term correction. The next most significant put walls are at $610 (1,565 OI) and $630 (1,239 OI).

Conversely, the call side is much thinner. The highest call open interest this Friday is at $1,210 (1,291 OI), followed by $1,000 (1,022 OI). These strikes are well out of the money. This distribution tells a clear story: The market expects a potential upside breakout to $1,000+, but the immediate fear is anchored around the $750 level. It’s as if traders are saying, "I believe in the long-term story, but I’m terrified of a short-term drop."

There were no significant whale block trades today, which is interesting. It means this positioning isn’t driven by a single frantic institutional move, but rather a broad-based consensus of caution. The lack of aggressive buying in the near-term calls (like the $960 strike with 947 OI) suggests that upside momentum is being met with skepticism.

Sales Growth vs. Technical Reality

Then there’s the news. Just yesterday, Costco reported July net sales of $23.12 billion, up 10.7% year-over-year. That is stellar. Comparable sales in the U.S. grew 10.3%, and digitally-enabled sales surged 17.7%. This is the kind of fundamental strength that usually drives stocks higher.

So why the bearish options positioning? It’s likely a "buy the rumor, sell the news" dynamic, or perhaps a technical correction after a long run. The K-line pattern summary notes a short-term bearish trend with a bearish engulfing pattern. The stock opened at $959.55 but has pulled back from an intraday high of $966.135 to trade around $953. The Relative Strength Index (RSI) is at 48.28, which is neutral but leaning slightly weak. It’s not oversold, but it’s not showing any explosive strength either.

The moving averages tell a mixed tale. The 30-day average is at $941.37, which acts as immediate support. However, the stock is still below the 100-day ($980.82) and 200-day ($957.96) averages. Being below the 200-day moving average is a key technical bearish signal for long-term trend followers. The market is essentially asking: "Is this a bounce in a downtrend, or the start of a new bull run?"

Actionable Trading Opportunities

Given this setup, here is how I’d approach the market today. We are in a range-bound environment with a bearish bias in the short term but strong fundamentals.

For the stock, I wouldn’t chase the open. The stock is currently at $953. A better entry would be near the 30-day support zone of $934.95–$936.17. If the price dips into that zone and holds, it’s a high-probability long entry. Your target would be the 200-day moving average around $958, with a secondary target at the 100-day average of $980. If it breaks below $934, the bearish trend accelerates, and you’d want to stay on the sidelines or look for shorts.

For options, the risk/reward favors defined-risk strategies. The heavy put wall at $750 is too far away to be a useful hedge for a quick trade. Instead, look at the upside potential if the bulls defend the $950 level.

Consider buying the COST20260807C960. This is an out-of-the-money call expiring this Friday. The open interest is 947, suggesting some interest, but it’s not crowded like the puts. If COST holds above $955 today and pushes back toward $966, this option has good gamma exposure. It’s a speculative bet on a bounce.

Alternatively, if you believe the bearish sentiment will prevail, look at the COST20260814P770. This is an out-of-the-money put expiring next Friday. The open interest is 1,518, which is significant. This gives you more time for a thesis to play out. If the stock breaks below the 30-day support of $935, this put will gain value. It’s a cheaper way to bet on a correction than buying the stock short.

Volatility on the Horizon

The disconnect between Costco’s stellar sales and the cautious options market is your opportunity. The fundamentals are screaming "buy," but the technicals and options flow are whispering "wait."

The $750 put wall is a distant safety net, not an immediate threat. The real action is in the $935–$960 range. If you’re a trader, respect the 200-day moving average at $957.96. A break above that confirms the trend reversal. A break below $935 confirms the bearish short-term trend.

Don’t let the strong sales numbers blind you to the technical resistance. The market is telling you that the easy money has been made, and now it’s time for a consolidation. Trade the range, not the headline.
