MRK Options Show Heavy Call OI at $120–$130 as Short-Term Bearish Setup Hints at Potential Breakout Play

• Merck (MRK) opens today at $114.66, currently trading at $114.38, slightly below the previous close.

• The stock is sitting within a short-term bearish K-line pattern, but long-term MA trends suggest an upward bias.

• Options market shows a strong call skew, with top OTM call OI concentrated between $120 and $130 for Friday expiration.

• Put/call open interest ratio stands at 0.82 — a bearish skew in favor of calls, suggesting a bullish market expectation.

Here’s the thing: Merck is in a tricky spot. On paper, the stock is drifting lower — today’s intraday low of $114.145 shows that. But the underlying trend isn’t giving up. The 200D MA is still way below the current price, and the 30D MA at $119.22 is like a ghostly ceiling it keeps bumping into.

Where Calls Are Concentrated and What That Means for Traders

If you look at the options chain, it’s clear the market is hedging a big move. Right now, the top OTM call options with the most open interest (OI) for this Friday (2026-03-20) are stacked between $120 and $130. The $120 strike has 9,275 open contracts — that’s a lot. Then comes the $123 strike at 8,043 contracts. Think of it like this: if you see heavy OI at those levels, it means a lot of money is expecting Merck to climb there — or at least not fall below it.

On the put side, there's some heavy volume too — the $105 strike has 7,072 puts with open interest. That’s not nothing. It shows some folks are still worried about a longer-term drawdown. But the call skew remains dominant.

There’s no notable whale activity today — no big block trades moving the needle. So what’s left is the balance between short-term bearish momentum and long-term bullish structure. The stock is testing its lower Bollinger Band at $112.32, and if it breaks below, that could be the trigger.

No Major News, But That Doesn’t Mean Much

One of the weird things about today’s Merck update is that there’s no company news to speak of — at least none that stands out in the last 48 hours. That can be both a blessing and a curse. On one hand, no earnings surprise or drug approval announcement means the market is moving based on pure technicals and options sentiment. On the other, it means we can’t tie the options activity to any real-world event.

But honestly, this is the best-case scenario for a tactical trader. With no news clouding the waters, the options market is speaking clearly: the crowd is leaning long-term bullish with a short-term bearish caution.

Specific Trading Ideas for This Friday and Next Friday

Okay, here’s what I’d consider for this week and next.

• Short-Term Call Buy for Friday: Buy MRK20260320C120. Why? Because the $120 strike has the most open interest and is right at the edge of the 30D MA. If Merck manages a small rebound or breaks above the $115 level, this call has the potential to get in line for a move up to $120. Entry cost is likely low due to the OTM nature of the strike.

• Next-Week Setup for a Longer Play: Buy MRK20260327C125. The $125 strike has 273 OI on Friday and is the second-highest call for next week. If Merck holds above the $114.145 intraday low and starts to test the 200D MA at $94.26 as a support, the stock could be primed for a bounce. A move up to $125 would put this call in the green.

• Stock Trade Setup: If you’re a directional trader, look for Merck to test the $112.32 lower Bollinger Band. If it holds, consider a buy near $113 with a target at $116 and a stop at $111.50. That’s a classic breakout play if the short-term bearish trend breaks.

Volatility on the Horizon and What to Watch

Here’s the bottom line: Merck is at a crossroads. The short-term indicators are bearish — RSI at 36.86 suggests oversold territory, and the MACD is negative. But the 30D MA at $119.22 is still in play, and the long-term trend is still up. So if you’re a trader, you need to be prepared for either side of the bet.

If Merck breaks above $115.76, that could be the green light for a bullish run toward $119.22. If it breaks below $114.14, then we may see a test of the lower Bollinger Band and the 200D MA. Either way, the options market is already pricing in a move — and that’s where the opportunity lies.
