BRK.B Calls Dominate as Price Breaches $520: Targeting the $525 Breakout

• BRK.B surges past $520, breaking short-term resistance with strong volume.
• Call open interest heavily clusters at $520 and $525, signaling bullish conviction.
• Put/Call ratio of 0.58 suggests traders are positioning for upside, not downside protection.
• Technical indicators confirm momentum, with MACD crossing above signal line.

Berkshire Hathaway Class B shares aren't just moving; they are marching. If you’ve been watching BRK.B from the sidelines, the noise of recent weeks has finally cleared into a clear directional path. The stock opened higher at $514.93 and pushed through the $520 mark, hitting an intraday high of $520.665. This isn't a fluke. The options market is screaming for upside, and the technicals are finally agreeing with the traders who’ve been buying the dip.

Here is why this setup matters right now.

The Options Market Is Betting on Higher

Let’s look at what the big money is doing. When you see a Put/Call ratio of 0.58 based on open interest, it means there are significantly more calls than puts out there. Specifically, we have 319,802 call contracts against 186,140 puts. That’s a clear bullish skew. Traders aren’t hedging; they are speculating on growth.

The most telling data point is the open interest concentration. For this Friday’s expiration, the $520 call has the highest open interest at 2,846 contracts, followed closely by the $512.5 call with 2,493 contracts. This is a massive wall of bullish sentiment right at current price levels. It suggests that market makers and institutional traders are comfortable with BRK.B staying above $512 and likely testing $520.

But look at next Friday. The $525 call jumps to the top of the list with 1,242 open interest contracts. This is a crucial detail. Traders are looking beyond this week, positioning for a move toward $525. The $520 call also retains significant interest (539 OI) for next week, indicating that $520 is becoming a new floor, not a ceiling.

On the downside, the put protection is sparse. The largest put open interest for this Friday is at $470, which is far below current prices. There is no immediate panic. The lack of heavy put buying at near-term strikes like $510 or $515 tells us that a sharp correction is not the base case scenario. However, we must acknowledge the risk. If the stock fails to hold $511.30 (today’s low), the lack of nearby put support could lead to a quick, unbuffered drop toward the $490-$491 support zone.

Notably, there were no significant whale block trades today. This absence is actually bullish in its own way. It means the move up isn’t driven by a single insider transaction or a large institutional dump. Instead, it’s a broad-based, organic accumulation. The trend is healthy because it’s not dependent on one player.

No News? That’s the News

You might notice there are no specific headlines or news events driving this move today. In the world of Berkshire Hathaway, this is normal. BRK.B is a proxy for the broader market’s health and Warren Buffett’s capital allocation genius. When there is no bad news, and the technicals are strong, the stock tends to drift higher on sheer momentum. The market narrative here is one of stability. Investors are rotating into quality, and BRK.B is the definition of quality. This lack of news amplifies the technical signal because there is no fundamental reason to doubt the uptrend.

Where to Trade It

So, what do you do with this information? Here are specific, actionable ideas for today.

For the stock itself, the trend is your friend. The 30-day moving average is at $496.9, and the 100-day is at $484.99. The price is well above both, confirming a strong short-term bullish trend. However, buying at $520 might feel like chasing. A better entry would be on a minor pullback. Consider entering near $514.50 if the stock retraces to test yesterday’s close or early intraday support. Your initial target should be the recent high of $520.67. If it breaks that with volume, the next psychological resistance is $525.

For options traders, the risk/reward is intriguing. Since the $520 call is the most liquid for this Friday, it offers tight spreads but limited upside if the stock runs. Instead, look at the BRK.B20260807C525. This contract is slightly out-of-the-money but aligns with the next Friday’s open interest data, suggesting a higher target. If you have a longer time horizon, the BRK.B20260814C525 is the standout choice. With 1,242 open interest contracts, it has liquidity and reflects the market’s expectation of a move to $525 within two weeks. It gives you a bit more time for the thesis to play out without the rapid theta decay of this week’s options.

Avoid the puts. The $470 put for this Friday has high open interest, but it’s too far out of the money to be useful for hedging a short-term move. You’re paying for insurance you likely won’t need.

Volatility on the Horizon

The setup for BRK.B is clean. We have a stock breaking out of a short-term consolidation, backed by heavy call buying and a low put/call ratio. The technicals, with an RSI of 65.88, show strength without being dangerously overbought. The MACD histogram is positive, confirming momentum.

The key is patience. Don’t chase the spike. Wait for a retest of the $514-$515 zone. If it holds, the path to $525 is open. The options market has already priced in this optimism, so your job is to execute with discipline. The bulls are in control, but always respect the $511.30 level. If that breaks, the thesis changes. Until then, the trend is up, and the calls are calling the shots.
