What is the 130-30 strategy?
The 130-30 strategy is a type of long/short equity approach used mostly by institutional managers and some active mutual funds or ETFs. In plain terms, a portfolio using 130-30 aims to hold 130% long exposure and 30% short exposure simultaneously. The net exposure is 100% (130% − 30%), while the gross exposure is 160% (|130%| + |30%|). The extra long exposure is funded by proceeds from short sales.
Key definitions
– Long position: owning shares; you profit if the price rises.
– Short position (shorting): borrowing and selling shares now to buy them back later; you profit if the price falls. Shorting requires a borrow and typically incurs fees and margin requirements.
– Net exposure: long exposure minus short exposure (shows directional market bet).
– Gross exposure: sum of absolute long and short exposures (shows total market risk taken).
How the strategy works — step by step
1. Stock ranking: The manager screens and ranks a universe (often an index like the S&P 500) by expected return using quantitative signals or fundamentals (e.g., momentum, valuation, analyst forecasts).
2. Allocate longs: Put 100% of starting capital into the top-ranked names.
3. Create shorts: Short the bottom-ranked names up to 30% of starting capital.
4. Reinvest proceeds: Use the cash generated from the 30% shorts to add an extra 30% of long exposure in the top names, bringing total long exposure to 130%.
5. Maintain exposures: Rebalance periodically to keep the 130/30 split and meet risk limits.
Why use it?
– Greater active tilt: By shorting perceived weak stocks and reallocating proceeds to strong ones, managers can increase active exposure to their best ideas without raising net market exposure.
– Flexibility: It allows expressing both positive and negative stock views.
– Potentially better information use: Shorting can be used not only to hedge but also to exploit expected underperformance.
Typical implementation details
– Universe: Often an index (e.g., S&P 500) or large-cap liquid stocks.
– Ranking method: Could be momentum, risk-adjusted returns, valuation, or multi-factor models.
– Rebalancing cadence: Monthly, quarterly, or when signals change materially.
– Constraints: Limits on single-stock concentrations, borrow availability, and margin.
Risk characteristics
– Shorting risk: Short positions have theoretically unlimited downside (stock price can rise without bound), whereas upside is limited to the initial sale price.
– Borrow and financing costs: Short sales involve borrow fees and margin interest; these reduce returns.
– Leverage and volatility: Gross exposure >100% increases volatility and drawdown potential compared with a plain long-only portfolio.
– Tracking/benchmark risk: The strategy is active; it can underperform benchmarks and long-only peers.
Checklist — setting up or evaluating a 130-30 product
– Universe liquidity: Are the chosen stocks easy to borrow and trade in size?
– Ranking methodology: Is the selection process transparent, testable, and consistent?
– Risk limits: Are position caps and stop rules defined for shorts and longs?
– Borrowing and margin costs: Are expected borrow rates disclosed and reasonable?
– Rebalancing rules: How often will the portfolio be adjusted?
– Fees and structure: Is the vehicle a mutual fund, ETF, or hedge fund, and how do fees compare to expected active edge?
– Governance and experience: Does the manager have a track record running long/short or extended equity strategies?
Small numeric example
Assume a manager starts with $1,000,000.
1. Initial longs (100%): invest $1,000,000 into top-ranked stocks.
2. Shorts (30%): short bottom-ranked stocks worth $300,000. Short sale proceeds add $300,000 in cash.
3. Additional longs (30%): reinvest the $300,000 from shorts into more of the top-ranked stocks.
Resulting exposures:
– Longs = $1,000,000 + $300,000 = $1,300,000 (130% of starting capital)
– Shorts = $300,000 (30%)
– Net exposure = $1,300,000 − $300,000 = $1,000,000 (100%)
– Gross exposure = $1,300,000 + $300,000 = $1,600,000 (160%)
Worked return example (simplified, ignoring fees and costs)
– Suppose longs (the $1,300,000 exposure) gain 5% over a period: gain = $1,300,000 × 0.05 = $65,000.
– Shorts (the $300,000 exposure) lose 2% (i.e., shorted securities rose 2%): loss = $300,000 × 0.02 = $6,000.
– Net portfolio gain = $65,000 − $6,000 = $59,000.
– Percentage return on starting capital = $59,000 / $1,000,000 = 5.9%.
This illustrates how magnified bets on long ideas can increase returns but also how short losses and borrow costs can offset gains.
Costs and implementation frictions to remember
– Borrow fees for shorts and margin interest reduce net returns.
– Short squeezes or constrained borrow availability can force early cover and losses.
– Transaction costs and turnover are often higher than long-only funds.
Who uses 130-30 strategies?
– Institutional asset managers and hedge funds seeking active extension of bets.
– Some mutual funds and ETFs offer 130-30 or “active-extension” versions for retail investors, albeit with varying fees and transparency.
Common variations
– 120-20, 150-50, 200-100: different long/short ratios with different gross exposures.
– Market-neutral (long = short) funds: aim for zero net exposure, unlike 130-30’s net long stance.
