Subject: Re: Value, when to buy
I used a four year simple moving average (SMA) of BRK price (four years because Jim used 16 quarters
...
where 'SMA' is a simple moving average of BRK price over the past four years.

Yahoo historical only gives daily, weekly, and monthly. Not yearly.

If/when I attempt to redo your interesting table, I'd be inclined to do monthly, maybe the last 48 months closing prices.
