BRK.B Options Signal: Heavy Call OI at $520 Suggests Upside Push, But RSI Overheat Demands Caution

• BRK.B trades at $515.61, breaking above the 200-day moving average with strong momentum.
• Call open interest dominates at the $520 strike, signaling a potential magnet for the price this week.
• RSI sits at 76.19, indicating the stock is overbought and due for a short-term pullback or consolidation.
• Total Put/Call ratio of 0.58 suggests a bullish sentiment, though lack of whale block trades implies retail-driven interest.

Berkshire Hathaway Class B shares are giving traders a fascinating mix of technical strength and options market optimism today. The stock opened slightly lower at $512.07 but quickly found buyers, pushing it to an intraday high of $516.25 before settling near $515.61. That’s a solid 0.48% gain on the day. But if you look closer at the options chain, the real story isn’t just the price action—it’s where the money is betting. The market is heavily positioned for a continued rise, at least in the short term, with significant open interest stacked at the $520 call strike. However, the technical indicators are flashing a caution light. We’re dealing with a stock that’s running hot, and while the trend is up, the risk of a sharp correction is real.

Calls Outnumber Puts at Key Resistance

When you look at the options distribution for this Friday’s expiration, the bias is unmistakably bullish. The top open interest for out-of-the-money (OTM) calls is concentrated at the $520 strike with 2,976 contracts, followed by $530 with 1,070 contracts. This clustering at $520 is critical. It’s just above the current price, acting as a psychological and technical barrier. For market makers, this level becomes a magnet. If the stock holds above $515, these calls could become in-the-money quickly, forcing hedging activity that might further propel the price upward.

On the flip side, the put side looks relatively quiet. The largest put open interest is at $470 with 1,737 contracts, which is far enough away from the current price to be more of a tail-risk hedge than an active bearish bet. The total Put/Call ratio for open interest stands at 0.587. Since this is below 1, it confirms that traders are buying more calls than puts. This imbalance suggests confidence. There were no significant whale block trades today, which means this move isn’t being driven by a single institutional player dumping or accumulating huge stakes. Instead, it looks like broad-based, perhaps even retail, optimism about Berkshire’s resilience.

No News, Just Numbers

Interestingly, there’s no breaking news from Berkshire Hathaway in the last few days to justify this specific surge. That’s actually a good sign. It means the move isn’t a reaction to a sudden earnings surprise or a CEO comment. It’s a pure technical and sentiment-driven rally. When there’s no negative news to counter the bullish options flow, the path of least resistance remains up. However, the absence of news also means there’s no fundamental catalyst to sustain a breakout above $520 indefinitely. Without new information, the rally relies entirely on momentum, which can evaporate quickly if support levels fail.

Trading Opportunities: Play the Bounce, Respect the Overbought Signal

So, what do we do with this? The data suggests a specific play. The $520 call is the key level. If you believe the momentum will carry through to this Friday, BRK.B20260807C520 offers a leveraged way to bet on that breakout. The open interest is highest there, meaning liquidity is good, and the gamma risk for market makers could squeeze the stock higher as it approaches that strike.

For the stock itself, chasing the high at $516.25 feels risky given the RSI of 76.19. A better approach is to wait for a pullback. The 200-day moving average sits around $490.48, but immediate support is tighter. Look for entry levels near $508–$510, which aligns with the intraday low and the lower boundary of today’s trading range. If the stock dips to $508 and holds, that’s a safer entry point for a swing trade targeting the $520 resistance.

If you’re looking at next Friday’s expiration, BRK.B20260814C525 is also interesting. With 1,327 contracts of open interest, it suggests traders are positioning for a move beyond this week’s $520 level. It’s a slightly more speculative bet, but it gives you extra time for the thesis to play out. Conversely, if you’re bearish on the overbought conditions, the $490 puts for this Friday (519 OI) offer a hedge, though the low put volume suggests this is a minority view.

Volatility on the Horizon

The trend is your friend, but it’s also your enemy when indicators are this stretched. BRK.B is in a short-term bullish trend, backed by strong call buying. But the RSI warns that the rubber band is stretched. The most likely scenario is a consolidation phase around $515–$520 as the market digests the recent gains. Traders should be cautious about new long entries at current prices. Wait for the pullback. If $510 holds, the bullish case remains intact. If it breaks, the next support lies much lower near the 200-day MA. Keep your stops tight, watch the $520 call wall, and let the options market tell you when the party might be over.
