Go-Go Years: The 1960s Performance-Fund Mania

Key Takeaways

• Go-Go funds chased short-term performance in glamour stocks, trading at unheard-of turnover rates.
• Star managers like Gerald Tsai and Fred Carr drew huge inflows on hot streaks.
• Many concept and conglomerate stocks fell 77 to 86 percent in 1969-1970.
• When the cycle broke, top performers became the worst, some funds losing 90 percent.

Background

By the early 1960s the US mutual fund industry was growing fast and changing character. Older funds had sold themselves on diversification and steady income. A new style sold something more exciting: raw performance, measured by who posted the biggest gain this quarter and this year. Equity fund assets doubled in the five years from 1960 to 1965 and doubled again from 1965 to 1970, on the way to a peak near $56 billion in 1972 (Bianco Research).

The figure who defined the era was Gerald Tsai. He joined Fidelity as a junior analyst and took over the Fidelity Capital Fund, the firm's first speculative public growth fund. Under him the fund grew from $12.3 million in 1959 to $340 million in 1965 (Bianco Research; Morningstar India). Tsai practiced what would later be called momentum investing, buying stocks with rising earnings and accelerating prices rather than cheap stocks, and turning his portfolio over at more than 100 percent a year, a pace almost unheard of among institutions at the time (Morningstar India).

In 1965 Tsai left Fidelity to launch his own firm. His reputation was so large that when he opened the Manhattan Fund, a planned offering of 2.5 million shares ballooned to 27 million, raising about $247 million, then the biggest offering ever for an investment company (Morningstar India; Bianco Research). He had become the first fund manager to get genuine celebrity treatment in the press, a template the rest of the industry rushed to copy.

The press gave these managers a nickname: gunslingers. They were young, confident, and openly focused on beating the market in the short run. Their language was the language of the boom, full of words like "performance," "concept," and "innovative," and in a good year they could make 40 or 50 percent on the money they ran. The investing public, now tens of millions of stockholders strong, handed them the cash to do it.

What Happened

The mania built through the middle of the decade, peaked in 1968, and broke in 1969-1970. The timing of Tsai's own fund is almost too neat: the Manhattan Fund began trading in February 1966, the same month the Dow Jones Industrial Average made its high of the decade (Bianco Research).

• 1958-1965: Gerald Tsai builds a record at Fidelity Capital Fund, lifting it from $12.3 million to $340 million (Bianco Research; Morningstar India).
• February 1966: Tsai's Manhattan Fund opens, raising about $247 million, the largest investment-company offering to that point, as the Dow hits its decade high (Morningstar India; Bianco Research).
• October 1966: Fred Carr, 36, takes over the Los Angeles-based Enterprise Fund (TIME, "Carr's Enterprise").
• 1967: The Enterprise Fund posts a 116.9 percent gain in net assets; its assets climb from under $20 million toward $250 million and its share price jumps from $3.77 to more than $9 (TIME).
• August 1967: Frederick Mates launches the Mates Investment Fund, another high-flyer of the era.
• December 1968: The Dow peaks at about 985, the high before the bust (A Wealth of Common Sense).
• March 30 to April 8, 1969: The SEC halts trading in Omega Equities, a thinly traded "letter stock" that the Mates Fund had marked far above its purchase price; the fund suspends redemptions.
• July 1968: The Manhattan Fund, despite its launch hype, ranks as the sixth-worst-performing fund in the country (Morningstar India).
• December 1969 to November 1970: A recession runs 11 months as the Federal Reserve tightens; the Dow falls toward about 631 by May 1970 (NBER; A Wealth of Common Sense).
• 1969: Tsai sells the Manhattan Fund to an insurer for about $30 million; the fund then loses about 90 percent of its value (Morningstar India; Bianco Research).

The damage was concentrated in exactly the stocks the Go-Go funds loved. In a study published in Dun's Review in January 1971, Max Shapiro looked at 30 leading glamour names and found the ten conglomerates down 86 percent, the ten computer stocks down 80 percent, and the ten technology stocks down 77 percent, for an average decline of 81 percent (A Wealth of Common Sense).

Why It Happened

The Go-Go mania ran on a feedback loop between performance, publicity, and inflows. A manager posted a big number, the press wrote it up, money poured in, and the new money bid the same favored stocks higher, which produced the next big number. The loop felt like skill. A lot of it was just momentum eating its own tail.

The first driver was the redefinition of success as short-term performance. When a fund is judged on this quarter's return, the manager is pushed toward whatever is rising fastest right now, not whatever is cheapest or safest. That meant crowding into a narrow set of growth, concept, and conglomerate stocks, and trading them hard. Turnover above 100 percent a year, normal for a gunslinger, is the opposite of patient ownership; it is a bet that you can keep guessing the next move correctly.

The second driver was the celebrity-manager culture itself. Once a Gerald Tsai or a Fred Carr became a name, inflows arrived because of the name, not because of careful analysis of what the fund owned. That made the funds enormous and concentrated at the same time. Size forced managers into the same large, popular stocks, so when sentiment turned, the same crowd needed to sell the same names with no fresh buyer waiting.

The third driver was a stretch into genuinely illiquid and hard-to-value holdings. Some funds bought "letter stock," unregistered shares sold privately at a discount and not freely tradable. A fund could carry letter stock at a generous mark and report a flattering net asset value. The Mates Fund's experience with Omega Equities, where a barely traded stock bought near $3.25 a share was valued around $16, showed how a single illiquid position could distort a fund's books until trading was halted and redemptions had to stop. The SEC made clear in 1969 that there is no automatic formula for valuing such restricted securities, which left those marks open to abuse.

The fourth driver was the macro turn that punctured the whole framework. Inflation had been building through the late 1960s, and in 1969 the Federal Reserve tightened policy hard, slowing money growth and raising rates to fight it (Kareken, Brookings). The economy fell into recession from December 1969 to November 1970 (NBER). Tight money is poison for richly valued growth stocks, and the speculative names the Go-Go funds held had the furthest to fall.

Aftermath

The Go-Go era did not end with mass fraud convictions or a wave of bankruptcies in the funds themselves. What collapsed was performance and trust. Funds that had topped the charts plunged to the bottom, and the public that had chased the gunslingers in pulled money out as the losses mounted. Tsai's Manhattan Fund, the symbol of the boom, went on to one of the worst long-run records of any fund up to that time after its 90 percent fall (Morningstar India; Bianco Research). Fred Carr left the Enterprise Fund around 1969, and the fund collapsed in the bust.

The letter-stock episodes pushed regulators to act on valuation and on how funds were run. The SEC's 1969 guidance stressed that restricted securities could not be valued by any automatic formula, putting the burden on directors to set fair marks. Congress then passed the Investment Company Amendments Act of 1970, which restricted sales charges and front-end loads, gave new responsibilities to independent fund directors, and, through Section 36(b), held a fund adviser and its board to a fiduciary duty regarding the fees charged to investors (SEC Historical Society).

The reputational damage was lasting. The 1970 bear market soured the public on mutual funds for years, and equity-fund flows stayed weak well into the early 1970s before the deeper 1973-1974 bear market hit the related Nifty Fifty growth stocks (Bianco Research). The celebrity-manager model did not disappear, but the specific claim that a star could deliver market-beating performance every year had been tested in real time and had failed.

Lessons for Investors

1. Performance chasing buys the top. Money flooded into Go-Go funds after the big returns, not before, so most investors bought in near the peak and rode the decline down. A record built in a roaring bull market tells you about the market more than about the manager. Treat a recent hot streak as a reason for caution, not confidence.

2. High turnover is a cost and a tell. Turning a portfolio over more than 100 percent a year, as the gunslingers did, means betting repeatedly that you can outguess the next move. It raises trading costs and signals that the strategy depends on momentum continuing. When momentum stops, that style has no floor under it.

3. Beware marks you cannot sell into. The letter-stock problem was that a fund could report a flattering value for a position no one could actually trade. If a holding is illiquid, its quoted value is an opinion, not a price. Ask how a fund or strategy would be valued in a forced sale, because that is the number that matters when redemptions come.

4. Concentration plus size is fragile. The big Go-Go funds owned the same narrow set of popular stocks, which lifted them on the way up and trapped them on the way down. When everyone holding the same names needs to sell at once, there is no buyer underneath. Crowded conviction is a risk, not a comfort.

5. The macro tide can sink the best story. The Go-Go stocks were broken not by company-specific failures alone but by Fed tightening and recession in 1969-1970, which crushed richly valued growth. No stock-picking skill cancels out a regime where money is getting tighter and valuations are compressing. Size your risk for the cycle you cannot control.

Frequently Asked Questions

What were the Go-Go years in simple terms? The Go-Go years were the mid-to-late 1960s, when aggressive mutual funds chased short-term performance by trading fast-rising growth and concept stocks. Star managers drew huge inflows, then many funds lost most of their value in the 1969-1970 bust.

Why did the Go-Go mania happen? Funds were judged on short-term performance, which pushed managers to crowd into the same hot growth and conglomerate stocks and trade them heavily. Celebrity managers pulled in large inflows that inflated those same stocks, until Fed tightening and recession in 1969-1970 broke the cycle.

How much money was lost in the Go-Go collapse? The glamour stocks fell hard: conglomerates about 86 percent, computer stocks 80 percent, and technology stocks 77 percent in 1969-1970. Gerald Tsai's Manhattan Fund, sold for about $30 million in 1969, then lost roughly 90 percent of its value.

Could the Go-Go era happen again today? The pattern recurs whenever performance chasing, celebrity managers, and crowding into a few hot names take over. Rules on fund fees, directors, and disclosure are stronger now after the 1970 reforms, but the human behavior behind the mania has not changed.

What is the main lesson from the Go-Go years? A dazzling short-term record is usually a product of a rising market and momentum, not durable skill. Chasing last year's top performer into crowded, illiquid, richly valued bets is how investors arrive precisely in time for the bust.
