Resilience and Returns

Timing the market is not a strategy for long-term growth. According to experts, there is never a "good" or "bad" time to get invested based on a "feeling." Financial professionals use rebalancing to help reduce market risk. Rebalancing isn't just portfolio best practice, it’s a powerful return enhancer. By selling what’s high and buying what’s low, you buy “the dips” and trim gains at peaks — a counterintuitive habit that yields long‑term benefits. As Research Affiliates concluded, “a disciplined rebalancing approach … raises the likelihood of improving long‑term risk‑adjusted investment returns.”*

What’s more, Vanguard researchers found that annual rebalancing offers the optimal blend of returns and cost control, harvesting much of the upside from the equity risk premium with minimal trading overhead.**

Annual Returns Comparison

Why Rebalance?

The PÜR 50-50 Strategy takes advantage of the powerful principle of annual rebalancing. Studies have shown that rebalancing can improve long-term risk-adjusted returns, reduce volatility, and help investors stick to their strategy. Instead of drifting with market cycles, you systematically capture gains and manage risk.

Our strategy was tested using IVV (iShares S&P 500 ETF by BlackRock) and QQQ (Invesco Nasdaq-100 ETF), two of the most traded and trusted ETFs. Scroll down to see how rebalancing compares to buy & hold and a simple benchmark.

Cumulative Growth Comparison

Case Study: Strategy Backtest (IVV + QQQ)

Backtesting over the past decade (with annual rebalancing enabled):

• PÜR Rebalanced grew more steadily than the Buy & Hold equivalent.
• It provided smoother returns, dividend accumulation of almost 4% annual yield, and capitalized on mean reversion in both growth and value segments.
