BRK.B Options Signal Bullish Momentum: Key Strikes and Block Trades Point to $520+ Move by Year-End

• Price action: BRK.B trades at $512.1, down 0.33% with volume surging to 1.39M shares.
• Options heat: Calls dominate open interest (324K vs. 191K puts), with heavy call OI at $520–$535 strikes.
• Block trade alert: Large put trades at $520–$530 strikes (expiring Sept 19) hint at institutional hedging.

Here’s the takeaway: BRK.B’s options market is pricing in a strong upside bias, with technicals and positioning aligning for a potential push above $520 this week. Let’s break down why—and where to focus your attention.

Bullish Sentiment Locked in OTM Calls, Hedging Pressure Below $500

BRK.B’s options chain tells a clear story. For Friday’s expiration (Dec 5), calls at $520 (OI: 3,418) and $530 (OI: 1,932) dominate, while next Friday’s chain sees even heavier interest at $535 (OI: 1,169). This isn’t just noise—it’s a vote of confidence from institutional players. The put/call ratio of 0.59 (calls > puts) reinforces the bullish tilt.

But don’t ignore the puts. The $495–$500 strikes (OI: 842–413) act as a floor for now. If BRK.B dips below $510, those puts could spark a rebound—or signal deeper caution.

Block trades add intrigue. Over 1,000 contracts of puts at $520–$530 (expiring Sept 19) were traded in bulk, likely by large investors hedging against a late-year pullback. It’s a reminder: even in bullish setups, volatility lurks.

No Major News, But Options Are the Story

There’s no recent headlines to anchor this move. BRK.B’s lack of news means the options-driven narrative is front and center. Without earnings or spinoffs to sway sentiment, traders are relying on technical levels and positioning. This creates a self-fulfilling dynamic: heavy call OI at $520 could push the stock there simply because institutions are betting on it.

Actionable Trades: Calls for Aggressive Bulls, Stock for Balanced Bets

For options traders, the BRKB20251205C520 (Dec 5 $520 call) is a high-conviction play. With the stock near $512, a break above $514.49 (intraday high) could trigger a rally toward this strike. If you want more time, the BRKB20251212C535 (Dec 12 $535 call) offers leverage on a stronger move.

Stock traders: Consider entries near $492 (30D support) if the stock holds above $510.72 (intraday low). A close above $514.49 would validate the bullish case, with price targets at $520 (Bollinger Band) and $525 (key call OI cluster).

Volatility on the Horizon: Positioning for BRK.B’s Year-End Move

BRK.B is at a crossroads. The short-term RSI (66.3) suggests momentum is intact, but the long-term 200D MA ($497.59) remains a critical anchor. If the stock holds above $492, the path to $530 becomes clearer. But watch the $510.72 level—it’s not just a support zone; it’s a psychological line. A breakdown here could reignite interest in the $495–$500 puts.

Bottom line: This week’s options activity and technical setup favor bulls. But in a stock like BRK.B—where Warren Buffett’s legacy meets macro-driven flows—caution is still warranted. Play the probabilities, not the certainties.
