Bill Miller (born 1950) is the investor who, as sole manager of the Legg Mason Value Trust from late 1990, beat the S&P 500 for fifteen consecutive calendar years — a mutual-fund record frequently likened to Joe DiMaggio's hitting streak or Cal Ripken's consecutive-games run. He later ran Miller Value Partners and its "Miller Blog" market letters.

The streak and its endCopy Anchor Link

Miller states the record's end plainly:

"Calendar year 2006 was the first year since I took over sole management of the Legg Mason Value Trust in the late fall of 1990 that the Fund trailed the return of the S&P 500."

He insists much of it was luck, borrowing Stephen Jay Gould's analysis of DiMaggio via colleague Michael Mauboussin, and concludes "There was, of course, a lot of luck involved in the streak."

Philosophy: value with a wide apertureCopy Anchor Link

Miller's definition of value is orthodox — buy below intrinsic-value — but he refused to equate "value" with low multiples, defending holdings like Dell and AOL at high P/E ratios during the late-1990s. His exit rule is explicit:

"we sell when a company's share price has reached fair value; we sell to replace an existing holding with a better bargain, and we sell when our original investment case is no longer applicable."

That placed him on the "quality/compounders" side of the quality-vs-statistical-cheap divide, against the value-must-be-statistically-cheap camp — a stance that became a live controversy through the 2008 drawdown, when his financial-heavy book collapsed with the housing and credit crisis (see value-traps for the counter-argument he rejected).

The crypto eraCopy Anchor Link

From 2014 onward Miller was among the first prominent value managers to own bitcoin. His 2020 framing:

"Its market capitalization is greater than JP Morgan and greater than Berkshire Hathaway and yet it is still very early in its adoption cycle."

Corpus coverageCopy Anchor Link

Miller's record here spans two archives: raw/investor-letters/MillerValue/Letters-Markdown/ (47 quarterly market letters, 1991Q1–2013Q4) and raw/investor-letters/MillerBlog/Letters-Markdown/ (16 letters, 2017Q3–2021Q3). The 2014–2017Q2 era lives on his blog and was not retrieved, and 2021Q4+ moved to "Market Observations" — both gaps flagged in the archive manifest. His precise 2008 annual-return figure is not cleanly restated in the retrieved text, so treat crisis-era returns as confidence: medium.
