How BRK-B price alerts work

Pick a target price or a % move for BRK-B. Computo watches the market — including pre-market and after-hours sessions — and notifies you the moment it triggers, then waits out a cooldown so you are never spammed. So you do not have to refresh the BRK-B live price all day to catch a move; set it once and we email you.

BRK-B price alerts — FAQ

Is a BRK-B price alert free?
Yes, for your first 14 days. Creating a BRK-B price alert on Computo starts with a free trial — no credit card required. After the trial, keep unlimited alerts, personal notes, and portfolios for $5/month or $50/year.
How do the price alerts work?
Computo watches BRK-B during market hours and notifies you the moment your target price or % move is hit, then waits out a cooldown so you are never spammed.
Do I need to install an app?
No. Computo runs in your browser. Create a free account, set your alert, and we handle the monitoring — there is nothing to install.
Can I set a target price or a percentage move for BRK-B?
Yes. Set an absolute price (for example, alert me when BRK-B crosses $200) or a daily percentage move (for example, alert me if BRK-B drops 5% in a day).
What is the BRK-B after-hours price?
When BRK-B is trading in the after-hours session, the live price at the top of this page is the after-hours price, with the regular-session close shown for reference. After-hours runs roughly 4:00–8:00 PM ET. Set a free alert and Computo emails you when BRK-B hits your target — even outside regular hours.
Does BRK-B trade pre-market?
Yes. BRK-B trades in the pre-market session before the regular open. When pre-market is active, the live price above is the pre-market price for BRK-B. Set a free price alert and we notify you the moment your target is hit, pre-market included.
