As a further follow-up to our discussion on the performance of index
funds vs. general equity funds, so far I have obtained the following
data from the Vanguard site:

S&P 500 % Funds
Annual Outperformed by
Year Gain Index
1972 85
1973 84
1974 47
1975 71
1976 56
1977 15
1978 6.5% 31
1979 18.4% 20
1980 32.4% 53
1981 -4.9% 37
1982 21.5% 38
1983 22.5% 60
1984 6.3% 78
1985 31.8% 74
1986 18.7% 76
1987 5.3% 76
1988 16.6% 59
1989 31.7% 82
1990 -3.1% 64
1991 30.5% 45
1992 7.6% 46
1993 10.1% 40
1994 1.3% 78
1995 37.6% 85
1996 23.0% 75
1997 33.4% 95

Average 17.4% 60
Std. Dev.13.1% 22

The first column is the year. The second column is the total annual
gain of the S&P 500 for each year. (Note that I am missing S&P 500
performance data for 1972 through 1977.) The third column is the
percentage of general equity funds that the Vanguard S&P 500 Index
Fund outperformed.

A review of the above data shows:
-the index fund outperformed an average of 51% of managed funds
during the two years that the market went down.
-the index fund outperformed 78% of managed funds the year the market
rose between 0 to 5%.
-the index fund outperformed an average of 58% of all funds during
years when the market was up 5 to 10%.
-the index fund outperformed 40% of general equity funds the year the
market went up between 10 and 15%.
-the index fund outperformed an average of 52% of equity funds during
years when the market went up between 15 and 20%.
-the index fund outperformed an average of 67% of equity funds during
years when the market went up more than 20%.
-the index fund outperformed an average of 60% of equity funds during
years when the market either went down or went up less than 5%.

Based on the data I have collected so far, it does not appear that
it is statistically correct to say that the outperformance of index
funds is limited to years when the market is up.

Does anyone else see a trend in the numbers or have additional data?

Best wishes,
