BRK_B Trading Guide: Pip Value, Spread & Strategy (2026)

Forget the lore about Warren Buffett. The only thing that matters when you're trading is the contract specs. BRK-B has a pip size of 0.01 and a pip value of $1 per share. The contract size is 1 share. That means if you buy 100 contracts, you own 100 shares. Simple.

The typical spread is $1, which is 100 pips. On a $400 stock, that's a 0.25% cost to get in and out. It's not nothing, but it's tight for a stock this size. The regular session runs from 14:30 to 21:00 UTC, which is the NYSE core hours. Here are the key metrics you need to know before placing a single order:

One more critical number: its beta is around 0.9. It moves slightly less than the S&P 500. This makes it more stable in a crash but slower to rocket during a rally. It's a tortoise, not a hare.

You trade BRK-B for its unique stability. It's not a tech stock that can swing 10% on an Elon Musk tweet. It's a massive, diversified conglomerate (insurance, railroads, energy, candy). This structure is its superpower and its curse.

The Good:

• Lower Gap Risk: It rarely gaps catastrophically on single-company news. The last true panic gaps were 2008 and March 2020.
• Predictable Correlations: It moves with the broader market (S&P 500) but with slightly dampened volatility. If you have a view on the general market direction, BRK-B is a cleaner way to play it than a volatile single stock.
• Institutional Flow: The order book is deep and dominated by big money. This means cleaner technical breaks and less random retail noise compared to meme stocks.

The Bad:

• Slower Moves: Don't expect 500-pip rips in an hour. Its daily Average True Range (ATR) is $3–$5 (300-500 pips). A big day is a 2% move.
• Buffett's Shadow: The stock can get sleepy. It needs a catalyst—earnings, the annual letter, a major acquisition rumor—to really wake up. I've held swing trades for a week waiting for a $10 move that a Tesla or Nvidia can do before lunch.

Timing is everything, and with BRK-B, the open and close are king. The highest-volume, most volatile 30-minute windows are at the 14:30 UTC open and just before the 21:00 UTC close. Pre-market (10:00–14:30 UTC) is for sentiment reading, not execution—spreads widen and liquidity is thin.

My rule: Scalpers live in the first and last 30 minutes of the regular session. Swing traders find more stable entries in the mid-session lull (15:30–19:00 UTC). And if you're trading an earnings release, set your orders in advance—the after-hours move can be the whole story.

At $400 per share, a $1 move is $100 on a 100-share position. The math is brutal if you're sloppy. Your first decision isn't where to place your stop; it's how many shares to buy.

The 1-2% Rule, Applied: On a $50,000 account, you risk $500-$1,000 per trade. Let's work backward with a realistic stop. BRK-B's daily ATR is $3–$5. A tight intraday stop might be $1.50 (150 pips). A swing stop might be $4 (400 pips).

• Tight Stop ($1.50 risk per share): Max position size = $500 / $1.50 = 333 shares.
• Wide Stop ($4.00 risk per share): Max position size = $500 / $4.00 = 125 shares.

See the trade-off? Tighter stops let you trade bigger size, but you'll get stopped out by noise more often. I learned this the hard way using 50-pip stops—I was right on direction but wrong on patience, getting whipsawed constantly.

Stop-Loss Logic:

• Intraday: Minimum 100-150 pips ($1.00-$1.50). Anything less is gambling.
• Swing: 300-500 pips ($3.00-$5.00). Respect the instrument's normal breathing room.

Berkshire's resilience supports wider stops. In March 2020, it dropped hard but recovered its pre-crash level in under 5 months. A single-sector stock might still be down 50%. That structural safety is why you can hold a bit longer.

1. Using Forex-Sized Stops: This is the big one. A 50-pip stop on EURUSD is standard. A 50-pip ($0.50) stop on a $400 stock is a rounding error. It will get hit by normal market noise 9 times out of 10. You're not trading a currency pair; you're trading a chunk of a massive company. Adjust your perspective.
2. Ignoring the Open/Close Dynamics: Trading BRK-B like it's EURUSD with 24-hour action is a mistake. The real money moves between 14:30 and 21:00 UTC. Placing a meaningful trade at 02:00 UTC is like shouting into an empty room—you might get filled, but the spread will be terrible and the move will be meaningless.
3. Overlooking the "Buffett Premium/Discount": The stock sometimes trades on narrative, not just numbers. When markets are fearful, BRK-B can act as a safe haven (premium). When markets are greedy for tech growth, it can lag (discount). I missed a great long entry in late 2022 because I was too focused on the P/E ratio and not on the fact that people were flocking to stability.
