What Judaism Teaches About Investing in Index Funds
Judaism may have the oldest asset-allocation advice on record. Ecclesiastes — traditionally read as Solomon's late-life reflection — advises dividing one's portion 'to seven or even to eight' precisely because 'you do not know what misfortune may occur on the earth' (11:2): an argument for diversification that modern finance would not improve for 2,500 years. The Torah's ideal woman 'considers a field and buys it' (Proverbs 31:16) — investment as virtue. Halakhically, public equities are standard; ribbit (interest) restrictions govern loans between Jews, not share ownership, and observant investors use compliant structures where relevant. The tradition's checks on accumulation are spiritual and practical: ma'aser and tzedakah obligations keep generosity structurally embedded, and the Talmud's question — 'when your wealth increases, set not your heart on it' (Psalm 62:10) — is recited in prayer. Jewish financial ethics prizes parnassah (honest livelihood) and warns, in Hillel's words, that the one who pursues a name loses it — but a diversified index held for decades is about as far from vanity as finance gets.
