Why IJR Beats the Russell 2000
Evaluation and Summary
Trail-Boss Radio examines why the iShares Core S&P Small-Cap ETF (IJR) has historically outperformed the Russell 2000 index over the past 30 years. The episode's central thesis is that the difference lies not in the companies themselves, but in how each index selects them. The S&P SmallCap 600 (which IJR tracks) applies a profitability screen, requiring companies to demonstrate positive earnings over four consecutive quarters plus the most recent quarter before inclusion. The Russell 2000, by contrast, casts a wider net and includes unprofitable companies. The episode presents historical data showing the S&P SmallCap 600 delivered approximately 10.85% annualized returns since 1994 versus 9.09% for the Russell 2000—a 1.75 percentage-point annual advantage—while also exhibiting slightly lower volatility. The S&P 600 beat the Russell 2000 in 93.9% of rolling five-year periods. The episode then profiles IJR specifically, highlighting its 0.06% expense ratio, $102 billion in assets, 600+ holdings, and straightforward structure without leverage or covered-call overlays. A key trade-off is acknowledged: the profitability filter means IJR misses speculative rallies in unprofitable companies during market manias (the 'dash for trash'). The episode frames this as a design choice rather than a flaw, positioning IJR as a 'dependable pack mule' for long-term ownership rather than short-term speculation. The broader lesson emphasized is that how you define the small-cap universe matters more than assuming small caps always outperform. The episode concludes by reframing the question from 'which ETF wins next?' to 'what kind of businesses do I want following me down a 20-year trail?'—emphasizing understanding index construction, rules, costs, and historical implications over prediction.
Verdict: A well-structured, clearly explained educational episode that delivers exactly what the title promises with solid data and practical insights into index construction, though it lacks guest interviews or deeper exploration of specific market scenarios.
