Anyone interested in taking a page from Buffett's playbook should learn how to buy Berkshire Hathaway stock, whether it's a good fit, and the differences between Class A and B shares.

How to buy Berkshire Hathaway stock

As one of the largest US companies and a member of the S&P 500 index, Berkshire Hathaway is readily available on many brokerage platforms. Chances are, if your broker offers US-based stocks, you'll have no issue finding Class A and B shares for Berkshire Hathaway. 

1. 1 Choose a reputable brokerage. First, sign up for one of the best brokerages in Canada. One that offers shares for American companies like Berkshire Hathaway. As you review different options, compare their reputation, fee schedules, and bonus features like retirement accounts to decide which is the best fit for your goals.
2. 2 Fund your trading account. Many brokerages let you link a bank account with a third-party service like Plaid and send ACH transfers for free. However, you may also be able to transfer money using other methods, including a debit card or fintech app like PayPal.
3. 3 Search for Berkshire Hathaway. Depending on the type of share you want, you can use one of two tickers associated with Berkshire Hathaway: "BRK-A" for Class A shares and " BRK-B" for Class B shares (more below).
4. 4 Choose between Class A versus B shares. Unless you're an institutional client or high-net-worth individual, chances are you'll be more interested in Class B shares. While both of these shares give price exposure to Berkshire Hathaway, BRK-B is far less expensive and easier to add to a portfolio.
5. 5 Enter the number of shares you want/can afford. Brokers may require investors to buy whole shares of Berkshire Hathaway, but some platforms offer fractional shares. Decide how much exposure you want to this company by selecting an amount of stock above the minimum threshold.
6. 6 Use a market or limit order. To get Berkshire Hathaway in your account as fast as possible, use a "market order" to fill immediately. However, if you'd like more precision over your trade, you could specify a desired share price with a limit order.

Berkshire Hathaway Class A vs B shares

Initially, Warren Buffett only offered one share for those interested in investing in Berkshire Hathaway.

Today, however, investors can choose between the original Class A shares or the more recent — and more affordable — Class B shares. So, what gives? 

There are a few reasons behind this separation. First, due to his long-term investment mindset, Warren Buffett wasn't a fan of splitting the original shares, as this might lead to an influx of speculative short-term traders.

Also, Buffett wanted to prevent unit trusts that would package Berkshire Hathaway shares and charge high fees. By introducing lower-priced Class B shares in the 1990s, he provided a more direct and affordable way for smaller investors to buy Berkshire Hathaway while avoiding a stock split and retaining original Class A investors.

About Berkshire Hathaway, Inc.

The origins of Berkshire Hathaway go back to the 1830s with the Valley Falls Company in Rhode Island. This textile mill eventually merged with Berkshire Manufacturing in 1955 to take on the name "Berkshire Hathaway" we know today.

However, it wasn't until 1965 that this company became an investment powerhouse when Warren Buffett took control and used it as a holding company for various investments. Today, Berkshire Hathaway holds a wide range of businesses, including GEICO, Dairy Queen, and Duracell, as well as significant stakes in companies like Coca-Cola, Apple, and Kraft-Heinz.
