- Bill Miller's firm sold its GameStop holdings during the initial Reddit-fueled frenzy.
- "I think our cost on it was around $4 or something," he told CNBC.
- He said firm has since shied away from GameStop and other so-called meme stocks that are popular on Reddit.
"We had GameStop in our deep-value product, and I think our cost on it was around $4 or something," Miller said in an interview on "The Exchange." "When it got into the $70s is when we sold it, then it of course went to $400."
However, the stock has remained both volatile and in focus as the video game retailer announces steps in its digital transformation. GameStop shares closed down 3.55% on Tuesday to $158.53 apiece, putting the company's market cap at roughly $11.1 billion.
The stock remains up roughly 740% year to date and more than 2,700% in the past 12 months. At this time last year, GameStop shares traded below $5.
Miller, founder and chief investment officer of Miller Value Partners, said his firm has shied away from GameStop and other so-called meme stocks that are popular with investors who are active on online message forums.
"They're not of interest right now because they're in the grip of the Reddit crowd and you're not able to actually analyze them in the same way you're able to other things because the price is dominating the fundamentals," said Miller, who managed a fund that beat the S&P 500 for 15 consecutive years while he worked at Legg Mason.
Miller also told CNBC he remains bullish on bitcoin, saying that demand continues to outpace supply of the world's largest cryptocurrency by market value. "That's all you really need to know, and that means it's going higher," he said.
