evaluate a trading system, compare it to the buy-hold Strategy (SPY). In addition to some trust funds and a few investment managers who do not use it, the strategy is invincible for most of the time. The efficient market hypothesis emphasizes that no one can beat the stock market, so everyone should buy index funds because it can reflect the composition of the market as a whole. The Spy is a trading Open Index fund (a trust fund that can be traded like a stock), and its price effectively reflec
